Book Review: Josh Volk, Build Your Own Farm Tools

Josh Volk, Build Your Own Farm Tools: Equipment and Systems for the Small-Scale Farm and Market Garden

Storey Publishing, August 2021

I knew from the start that I would like this book! Who among us hasn’t wrestled with tools that aren’t quite right, that we spent good money on? Handle too short? Wrong angle? Made for very large hands? Who hasn’t wished for a tool that isn’t commercially available yet?

The book is clearly illustrated with accurate line drawings – better than photos because there’s no extraneous stuff. The first chapter, Setting Up a Basic Shop, covers safety, tools, benches, tool use and maintenance. Having safety notes at the beginning is wise. Yes, don’t wear gloves when working near rotating machinery. Clear space around your work area and have good lighting. When needed, use ear protection, goggles, mask, helmet. No farmer wants an injury. We rely on our bodies to get our work done. Josh writes good advice.

The lists of basic tools are helpful, as is the beginner’s guide to driving screws, a task which many of us were not taught at home or school. I encourage everyone to read the introductory chapter. Even if you know it all, you may pick up a good way to explain things to your helpers. Given the other safety precautions, I was surprised we are not warned against spreading linseed oil rags out to air-dry after oiling tool handles. They self-ignite – we burned a building down that way!

The common materials used include wood (SPF, or spruce, pine, fir) and CDX plywood (grades C and D); hot-rolled low-carbon steel, black steel pipe, and polyethylene, PVC and ABS plastic piping (with environmental concerns elucidated).

There are 19 projects, all made and used by the author and farmer friends. All can be built with commonly available tools and materials. There are clear instructions, a description of how the tool is used, and options for design modifications, including how you can apply the design features to other tools you might make. I instantly saw the wisdom of having a three-legged sawhorse for uneven ground – the milking stool principle applies!

The greenhouse projects start with a simple potting bench made from standard size lumber. Make the height to fit the users. The slatted top is 42” x 8’, and you can customize by installing irrigation sprinklers, or hot water spaghetti tubing between the slats for a bottom-heating system, and/or insulation under the slats to prevent drafts from below.

Three homemade hoes are next., followed by a germination chamber made from wire shelving (as used in restaurant kitchens), surrounded by ½” exterior grade insulation board. Josh’s example holds 27 10×20 flats, and fits under their seeding bench. The heating is provided by a metal pan of water with a submersible 500 watt thermostatically-controlled aquarium heater.

A legless cantilevered potting bench with compost mixing tub follows. The key is to first find a tub the right size for your operation and build around it. Make a sliding plywood lid to cover the tub.

The field tool projects start with benders for making hoops from metal EMT conduit or chain-link fencing top-rail. You’ll need a different bender for each pipe size, and for each hoop size, but as they are made from scrap wood fastened onto vertical posts, you can line up a whole set in your barn. Instructions are included for drawing circles on wood, and calculating the pipe length for a given hoop diameter.

Next is a rolling bed marker. I once made one from plastic piping, following poor instructions online. It never worked. I don’t think it had been field-tested by the designer. No danger of that here! This design uses wood throughout, and marks lines across the bed every 12”, for rectangular plantings of three rows. You could modify it for more rows, or closer spacings, although not to mark a hexagonal (offset) grid, where plants are equally spaced in all directions. Josh recommends making just one roller and using a 1-2-3 row choice with a 3-row roller or 1-2-4 row options with a 4-row roller. The 4-row roller can be used to plant 1-2-3-4-5-7 rows if you eyeball rows between the marked rows. Likewise, by planting between the lines across the bed, you can create plant spacings of 4-6-8-9-12-15-18”. Rolling bed markers work best when pulled over fairly flat bare soil, soon after raking or tilling. This project is more exacting than many in the book, although it’s just labeled “moderate”. The easy-looking drip tape winder is also “moderate”. Even the hand cart, which involves some welding, is graded “moderate”!

The hand cart has bicycle wheels (smooth rolling), and a higher bed than the commercially-available carts (less bending and lifting), can roll over planted beds (higher clearance), and has good balance so the load doesn’t shift in use. The frame is made from plain steel square tube. The handle is round tubing, and the fork legs for the wheels are flat steel. You can make a flat plywood bed to sit on top of the steel framework. It has no side walls, just a short rail at the back, making it easy to load, unload, or use as a workbench in the field.

The irrigation tools chapter includes a stand with mounted drum to reroll drip tape, and an easy-to-move sprinkler system. The drip system section includes the calculations for applying the amount of water needed. There are also explanations of hose threads and pipe threads and why they don’t fit together, and how to use various driptape fittings. It’s possible to unroll two lengths of driptape at once off a new roll by fastening the free end to the mainline pipe and walking out a loop of tape. You can actually leave the two lengths connected, saving yourself end caps. The drip tape tutorial is very user-friendly, leading you through their real-life example.

The sprinkler system mimics the K-line system used in pastures. It has sprinklers on sled bases connected by ¾” flexible poly irrigation tubing. The sprinklers are either pop-up lawn sprinklers, Wobblers or Nelson Windfighter ag sprinklers. PVC pipe nipples attach the sprinklers to the sled bases.

Josh includes a heart-warming page on the importance of finding good mentors “with a crafter’s mind” as Washington State farmer Rohn Amegatcher calls it. Learning this approach from a person who puzzles through challenges and fixes things themselves is worth even more than learning a particular fix.

The wash and pack tools start with a hand truck mini-pallet. Stack your crates up on one of these pallets, then move them with your hand truck. You can make these from scrap wood as it becomes available and you have time, or you can have an off-season project to make a set of 20.

Next is an onion bag filling stand, that works equally well for potatoes or other root crops. Oh! This project is graded moderate to difficult! I don’t see why. A simple spray table is up next, a slatted table with a slanted metal diverter below it (to keep your feet dry!) and side racks. There’s a page of design notes including making the table height, width and depth fit the humans.  Important because the workers will be there for some time.

The barrel washer page by Josh Volk

The barrel washer is next. We’ve long wanted one of these, but prices of ready-made ones are high. These instructions could help us make our own. This project has a high level of complexity, so I should make something easier first! The compact design (4’ long) uses less water than the big ones, and suits small-scale farms. You can add a gate to keep the water in the barrel for longer, saving water. The frame uses aluminum bicycle wheels. The water supply runs from a garden hose into a length of PVC piping with three clip-on nozzles that can easily be removed for cleaning or replacement. There’s a flow-rate calculation page, and instructions on how to use the barrel washer manually or add a ¼ hp motor. There are tips for diverting and collecting the water that runs out, letting it settle and recirculating it as the first wash water. Design notes help you understand and optimize the washer.

A rolling packing table with a shelf for labels, tape, markers, order sheets is next. The table height adjusts for different workers, and the table surface is a store-bought plastic folding table, which can be removed and used as a regular table if your needs change. Most of the rest is plywood and standard lumber (plus casters). It’s straightforward to make but does require accuracy for smooth-operation.

If you want to move away from plastic crates, and have an upmarket look, the lightweight, lidded easy-to-carry CSA boxes are for you. Make them to fit efficiently in your vehicle and to hold a whole number of whatever size bags you pack into.

Next we move into the office. The main tools are computer, phone, pencil and paper. Josh explains, in 13 pages, how he uses spreadsheets, working back from his harvest goals to his planting schedule and field maps. If you are new to crop planning, this is a good primer.

You can quickly make your spreadsheet serve your needs. You can make a plan for a single CSA share, then multiply by the number of shares to get your harvest quantity. You can add in expected market sales, then proceed to make your Planting Plan.

Copy your Harvest Plan onto a new spreadsheet and parse it out into every single planting and the date to plant to meet your harvest date. You’ll need the days to maturity number, with a little wiggle room added. Include columns for the row length and the total space needed, in beds or in length x width areas. Make a greenhouse seedlings schedule for all the crops you transplant.

Sort your spreadsheets by date for your schedules, and in an alphabetical list of crops for seed ordering. You can even use spreadsheets to make your maps. If you record what actually happens, next year’s schedules and maps will be more fine-tuned to reality.

Will a tool pay for itself? It’s easy to get beguiled by shiny new tools. Sometimes this leads to buyer’s remorse. Josh lists out parts of the overall cost, including environmental costs. Benefits include saved time, increased yield, improved ergonomics and morale. The lifespan of the tool and its maintenance costs affect the cost per year of use, and the time it takes for the tool to pay for itself. As an example, Josh looks at the rolling bed marker. Cost of materials plus labor to build it, versus time saved each use, times number of times used per year x labor cost of that time. It pays for itself in just under two years. Additionally, the time used to build it is in the off-season and the time saved is in the busy season.

List the questions you need to answer and find an easy way to record the answers while you are using the tool. It’s easy to record packing data on record sheets in the packing shed.  But in the field? Clipboards and paper, or pocket notebooks are useful too. Investigate whether it is actually more efficient for your crew to write information on paper, and later have someone transfer it onto a spreadsheet or database, or if it’s easier to have each person input directly on their phone, or a barn tablet. Google Forms may be useful for time studies of tasks. Different answers suit different people.

It can be particularly helpful to have your weekly “to do” list on your phone. Phones are useful to set reminders to turn off irrigation, and photos can record water meter readings before and after. A video will tell you how long something takes. Or take a photo at the start and end of a task, and use the embedded times for your calculation. Having a step to complete in the shade is no bad thing!

My review copy was a digital advance reader copy and I had to be patient and accept not being able to easily flip through the whole thing. I also had to deal with bits that still needed editing, that I assume will be. Why are there no metric equivalents throughout? Just conversion ratios for length, weight and temperature at the end of the book. Yes, we can convert, but it would have been easier if the book had included them.

The appendices include basic math for tool design, length, area and volume, practical triangles and trigonometry, circles, and calculating and converting rates such as water flow and slope rise. I’m fortunate to be math literate, but I’ve found not everyone can do seat-of-the-pants mental arithmetic to figure how many stakes are needed for a certain bed length. Sad but true.

The section explaining mechanical principles is useful for those of us lacking an engineering or physics background. Force, strength, stress and strain are all explained in terms of a bag of potting mix on a table, and bending forces are explained setting it on the edge of a cantilevered table. The explanation of torque examines the casters on a barrel washer, and a wrench on a nut. Flow rate and pressure are practical aspects of fluid dynamics. If your irrigation flow rate exceeds the maximum available, the pressure will drop. Pressure is generated by pumps, or by setting the water source higher up than the area to be watered. Pressure drops over the length of the piping, particularly at fittings. Use pipe runs that are as straight and short as possible, with the fewest fittings to restrict the flow. Small losses can add up.

The section on basic materials properties explains what you can expect from wood, steel, aluminum, PVC, and concrete. This book scores well on diversity of people-types in the drawings. – Who did those wonderful drawings? My copy didn’t include that info.

This very handy practical book deserves a place in your shop, barn or shed. You’ll refer to it often.

Book Review: Sally Morgan, The Healthy Vegetable Garden: A natural, chemical-free approach to soil, biodiversity and managing pests and diseases.

Chelsea Green Publishing, September 2021

Sally Morgan is an expert organic gardener in the UK. She is the editor of Organic Farming Magazine for the Soil Association, the nation’s foremost non-profit organic gardening and farming membership organization. Her book The Healthy Vegetable Garden is clearly and concisely written. Sally promotes building healthy soil, boosting biodiversity, creating habitats to attract pollinators and predators, making good use of water, promoting the stability and resilience of natural ecosystems, and integrating the landscape with people.

A healthy garden maintains a balance where pest organisms are at a non-damaging level, (rather than eliminated entirely). Here you will find lots of solid information to identify pests and diseases and deal with them using regenerative principles, and when necessary, making traps and lures.

The book has some info particularly for US gardeners – you’ll be able to read about Mexican bean beetle and Colorado potato beetle! You might be mystified by some of the European details we don’t have to deal with, such as raspberry beetle or flatworms. As long as you have some prior gardening experience where you live now, you can only benefit from the information offered here. Brand new US gardeners might get confused.

The Healthy Vegetable Garden has good descriptions of soil and its components, structure, assessment, and testing. It is important to nurture healthy soils producing healthy plants, with the essential minerals and vitamins we need for health. Nutrient density has declined seriously over the last 70 years, particularly levels of calcium, iron and vitamins B and C. In 2014, the UN warned that we had only 60 years of harvests left, if we continued degrading our soils. In 2020 a new study estimated that 90% of soils had only 100 years of harvests left. Soils managed with conservation techniques have much longer projected lifespans.

The second chapter is about ways to regenerate soils, by minimizing tilling or digging, adding compost, mulches and cover crops. The living mulch section is where I am hesitant. My experience and that of Jesse Frost whose Living Soil Handbook I reviewed recently, is that living mulches can out-compete the crop if we are not skilled and careful. The author does point out the need to cut back the mulch to prevent this problem. Growers in the south might find planting zucchini (courgettes) into white clover impractical as zucchini is a fast-turnaround crop for us, whereas clover is a slow-growing cover crop. The author leaves the clover growing through the following winter, to make the combo work. In the chillier parts of the UK, only one crop of zucchini can be grown in a summer, so the system makes sense. In Virginia, we plant zucchini and summer squash 5 times outdoors. Likewise, the speed with which chickweed flowers and sets seed in Virginia would make it unwise to regard it as a cover crop! I did like the idea of undersowing tomatoes with coriander, if I wanted large volumes of coriander (cilantro).

The chapter on understanding pests and diseases is well-written, although we in the US have so many more than in the UK! Plant pests are listed in categories by their method of causing harm, rather than by individual names, which helps understanding. Plant pathogens likewise are described by type, as bacteria, viruses, fungi, water-molds. Fungal pathogens include biotrophs (parasitic pathogens such as downy mildews, rusts and smuts), semi-biotrophs that spend part of their lifecycle on the host, then part feeding saprophytically on the host’s dead remains (such as apple scab, Phytophthora blights, Botrytis-type molds and powdery mildews) and necrotrophs that kill their host and then feed as saprophytes. I appreciated the bigger understanding this classification of pathogenic fungi gave me.

Heed the warning that climate change is bringing new pests and diseases, and the chilling news that for every 1 Celsius degree rise in average temperature (about 2 F degrees), aphids become active two weeks earlier. Some warm climate diseases will move further towards the poles. The author recommends paying attention, encouraging good airflow around plants, sanitizing pruning tools, and planting rows of tall plants to break up the progress of air-borne fungal spores.  Growing potatoes downwind of a row of Jerusalem artichokes is a good example.

Sally is very practical on the subject of sterilizing pots and flats – your tools, boots, gloves and hands are as likely to spread spores, don’t worry about sterilizing pots! Some of the disinfectants suggested in other books can do more damage! Likewise, most spores don’t survive long on the ground, removed from their host plants, and so such diseased crops can be safely composted in a hot compost process. Practice crop rotation to deplete those that do survive in the soil, such as carrot rust flies.

Under normal conditions, predators can prevent pest outbreaks, but problems arise when conditions change quickly and disrupt the balance of prey and predator. If you see lots of pests, find a way to deal with them that won’t also kill their predators and parasites. Beware broad spectrum pesticides and fungicides, even if Organic. Encourage ladybugs and beetles by creating “ladybug hotels” and “beetle banks”. (There are some photos to inspire you.)

Plant for a continuous supply of insect-attracting blooms. Yarrow, ajuga, alyssum, dill, and fennel flower early in the year and attract predators like hoverflies, ladybugs, lacewings, tachinid flies, and parasitic wasps. Also grow early blooming flowers with pollen and nectar predators can use as alternative foods – borage is fast at producing nectar, as are dandelions. Phacelia is a very attractive to predators, especially aphid predators like hoverflies and parasitic wasps. Sow in the fall for early spring blooms. Angelica is a biennial that can flower in the spring of its second year. If you decide to trust to weeds to feed your beneficial insects, take care about how much seed they sow! This is a risk I do not recommend taking, especially in warm climates with rapid rates of growth.

In the section on crop rotations, polyculture and continuous cropping, Sally reports that she has moved away from a rigid crop rotation for many crops, following Elaine Ingham’s observation that nature does not rotate. This may be a place where home gardeners and production gardeners diverge. Mixed beds with several crops work well for manual work, but less so for those with rototillers, or even those hoping to make fast progress with a scuffle hoe. Mixed plantings are attractive and fun for the solo gardener, but having others pull up your delightful medley suggests it doesn’t work so well for bigger operations.

This book is not dogmatic. Rotations help disrupt pest and disease cycles, and here you can read brief descriptions of three-crop, four-crop and eight-crop rotations. You can also devise ad-hoc rotations and grow beds of different crops next to each other, in order to benefit from diversity without slowing down your hoeing or putting a bed out of commission while you wait for the last item in that bed to finish its lifecycle.

Shumei Natural Agriculture Farm, Yatesbury, Calne, in SW England has been increasing yields year by year, with no rotation, no pesticides, and no fertilizers other than material from immediately around the beds that is incorporated into the soil. You can’t successfully switch instantly to this method of growing, because it takes time and lots of the right microbes for the soil to adapt. Charles Dowding is experimenting with this at Homeacres, his garden in Somerset. Continuous cropping is a challenging idea to those of us who came up when organics was the opposite of industrial monocropping. We championed rotations.

The author provides a list of perennial vegetables she is growing: Chinese artichokes, Jerusalem artichokes, globe artichokes, Good king henry, lovage, perennial kales, scorzonera, sea beet, sea kale, skirret, Babington leeks, potato onions, walking onions, and Welsh onions. No rotation is used for these no-dig crops, which grow with a layer of leaf litter on the soil.

Agroforestry is the practice of growing vegetables in wide alleys between trees. Sally has tried this by planting a row of cordon apples (trees trained to a single stem) along the edge of a vegetable bed. US readers should not follow her exact hedge design plan, as autumn olive, blackthorn and dog rose, for example, are invasive here.

Part 4 of the book is on boosting defenses, and how biocontrol works. This is the use of one organism to control a pest or disease. It is important to learn about the pests you have and their particular biocontrols. It’s not a case of opening the bag and throwing the stuff on!  Biocontrols have specific requirements, such as temperature or moisture. Timing is important.

Parasitic wasps, minute pirate bugs and predatory mites like Phystoseilus persimilis (which eats spider mites) can be introduced for their appropriate prey. Try to save biocontrols for when you really have a problem, and make sure you correctly identify the pest you want to control.

Predatory nematodes each have their own mutualistic bacteria living in their gut. When the predatory nematode works its way into its prey, it releases its bacteria, which kill and digest the prey. Reminds me of the Trojan Horse! The process happens below ground – nothing to see here! I found this fascinating! Nematodes need a film of water to live and move in, and temperatures above 41˚F (5˚C). Buy the right nematodes (and bacteria) for each job. This book has a two-page spread on which parasitic nematode to use for which pest. I have not seen this quality of information in any other book! Nematodes can be used to manage slugs, weevils, carrot rust fly, cutworms, onion fly, gooseberry sawfly, thrips, codling moth and more.

Plants have their own protective species. The introduction to the rhizosphere (microbiome around the roots) includes fascinating details on a type of morel mushroom that farms bacteria! Soil fungi are important for most crops, except brassicas and chenopods (beets, spinach and chard). We hear about the rhizosphere, but not the phyllosphere, the equivalent collection of micro-organisms on the leaves. This is mainly, but not only, composed of bacteria. About 10 billion on one leaf, and all different from the bacteria in the soil, and varying from one crop to another! Young leaves have mostly bacteria, mature leaves have more yeasts and senescent leaves mostly filamentous fungi. These microbes protect the plant’s health, supply biofertilizers, biostimulants and biopesticides. Some leaf bacteria suppress growth in caterpillars feeding on the leaf. Understanding this helps us appreciate the reasons for not spraying plants haphazardly with things that “might help”.

Plants have an arsenal of defenses. Thorns and hairs are just the most obvious. Some plants stockpile toxins to provide fast response to insect attack, others manufacture them as needed. When attacked, many plants respond by toughening up their cell walls in the area being attacked. Plants release various volatile compounds communicating with other plants and with insects (both the pests and predators of those pests). The example given is that when corn roots are attacked by a certain larva, the roots release a compound that attracts a nematode that is a predator of that larva. Sometimes, though, the attacker wins, as when certain beetles release their own volatile compounds in response to a plant’s compounds, signaling to other beetles to join the attack. Colorado potato beetles do this. This complexity calls our interventions into question: is it helpful to handpick the pests? Not if the pests call on comrades to join the fight.

If your soil is already healthy and rich in microbes, Sally thinks additions are not needed, including biostimulants, compost teas and foliar sprays to boost the numbers of beneficial bacteria and fungi. Biofungicides can prevent particular soil-borne diseases, but can’t cure them after the fact. Biofumigation is the process of growing a particular cover crop, chopping it finely and incorporating it into the oil, taking advantage of the allelopathic compounds released, to kill pests, diseases or weed seeds. Mustards, radishes and forage sorghum all have bio-fumigant properties.

The chapter on barriers, lures, traps and sprays includes recipes, and the caution that many homemade sprays kill beneficials as well as pests, as do some of the Organic commercial sprays like neem, Spinosad, quassia. Use these only as a last resort, and pay attention to dilution rates, time of day to spray and frequency of use.

Here you can find instructions for carefully treating seeds with a disease-fighting hot water treatment before planting. You can also find cautions, such as not heat-treating peas, beans, corn, cucumbers, lettuce or beets. Or old seed, as the germination rate might deteriorate too far.

Part 5 of the book is an A-Z of Pests and Disease. First are aphids – there are so many kinds of aphids! The lifecycle of aphids starts in spring with eggs hatching into wingless females that give birth via parthenogenesis to more females. Within a week, one female can produce 100 clones, which can repeat the process at the age of one week.  This continues until adverse weather or predators trigger production of a generation of winged female aphids that moves to new plants. Later in summer male aphids are born and females lay fertilized eggs that overwinter on host plants, to hatch the following spring.

Handpicking aphids is likely impossible, so start by blasting them off the plants with a water jet from a hose. This may decrease the population enough for natural predators to begin control. Failing this, a soap spray can be effective, although aphid predators will also be harmed. If you plant before any aphids arrive, you can use a fine mesh netting to keep them off, but monitor to make sure no aphids have got inside the net. You could try trap crops of nasturtiums to draw aphids away from your crop, but how much of your space do you want to devote to nasturtiums, and how do you deal with aphids then? The same choices of water and soap.

The list of pests continues through the alphabet. For some, nasturtiums can act as a repellent rather than a trap crop. Cucumber beetles are a good example. Nasturtiums are a brassica, and will attract cabbage caterpillars if there are no other brassicas around. There are two pages on making the garden inhospitable to slugs and snails and three pages of control options including beneficial nematodes, ducks, coffee grounds (acidic and non-specific) and iron phosphate pellets.  Finally, there are whitefly and wireworms.

The disease chapter starts with various blights, including two pages on potato blight (both types). Cankers, club root, damping off fungi, mildews, molds, rots, rusts, spots, scabs, viruses, and on with the sad list to end with wilts. It makes sense in an organizational way to end with the problems, but it makes for a sorry place to leave off.

This book is good on detailed info on soil micro-organisms and the general theme works globally. I recommend checking against local Extension Service or eOrganic before following any of the specific techniques, to ensure it’s likely to succeed where you live.

Book Review: Pawpaws, The Complete Growing and Marketing Guide by Blake Cothron

Pawpaws: The Complete Growing and Marketing Guide by Blake Cothron, New Society Publishers, 2021, $29.99

“Blake Cothron is an authority on pawpaws, and provides a clear, detailed guide for commercial success in growing this “oddly appealing species” (his own words). The supply of this exotic, trending, easy-to-grow fruit has not yet met the demand. Blake shares the wealth of his knowledge, including challenges, and when he doesn’t know, he says so (and it’s probable that others don’t know either.)”

This is the advance praise I wrote for Pawpaws, now inside the front cover. Last fall I reviewed Michael Judd’s For the Love of Pawpaws, a permaculturist’s take on growing pawpaws among diversified crops. Blake’s book, while mainly intended for small-scale organic commercial growers, is equally useful for the backyard enthusiast. Blake ensures you have the information you need to choose what to grow, where to buy it, how to plant it, keep it thriving, prune and harvest. Depending on your scale, you can try the nine exquisite recipes here, or sell gourmet pawpaws online, or make value-added products such as craft brews, jams, and baked goods.

Blake and his wife Rachel Cothron, own Peaceful Heritage Nursery, a 4-acre USDA Certified Organic research farm, orchard, and edible plant nursery, near Louisville, Kentucky, the perfect climate for pawpaws.

America’s almost forgotten native fruit looks tropical and has an exotic appeal, but is an easy to grow temperate climate tree, and very cold hardy (US Winter hardiness zone 5, -20˚F/-29˚C). It is ripe for 4-6 weeks in late August-September. Although mostly grown in the South-east and Mid-Atlantic, pawpaws will grow in portions of 26 US states. Avoid confusion with the tropical papaya, which is sometimes also called pawpaw. The North American pawpaw is Asimina triloba.

The book is studded with cultural gems such as that you can sometimes locate the site of an old native American village by the clusters of pawpaws still growing there.

Blake Cothron

There are some false myths about pawpaws, including the idea that they are secretly tropical and related to bananas, papaya and mango, They are not. The second myth is that they grow best in shade. Also not true! They can grow in shade, but will not produce good fruit unless in full sun. A third myth is that they are ripe when blackened by frost. Oh no! They are usually ripe weeks before frost. Frost is not a benefit, but a cause of damage! (This myth is not true of persimmons either.) Another myth is that the flowers smell really bad. It’s just not true. Lastly, a myth that would be nice if true: pawpaws are not immune to all diseases and pests. Certainly they don’t suffer from as many health challenges as apples or peaches, but there are pawpaw troubles as Blake explains. All these stories show how important it is to have a trustworthy guidebook.

Wild pawpaws are found as thickets of suckers growing up from the enmeshed roots of older trees, or as clusters of seedlings around a mother tree. They may feed wild animals, but will not grow the large tasty fruits humans want. Suckers are clones of the mother tree, and as pawpaws are rarely self-fertile, these thickets do not produce fruit. For human food, pawpaw trees need full sun, well-draining soil and plenty of space. Not what you might have assumed. Read this book!

Wild pawpaws are most often found in moist lowland areas near water, but in well-draining areas, not swampland. They are often on sunny slopes (not northerly sides). They can be found along edges of clearings, trails and old roadways. In Kentucky, Blake reports about 25% of the wild pawpaws are tasty, 50% are edible and 25% are “spitters”. If you’ve experienced anything other than the top 25%, this book can be your encouragement to try some cultivated types.

When you buy pawpaw trees, go for potted 1-4ft grafted trees at $30-$50 each. These will survive for 15-20 years and provide harvests for 10-15 of those. During that time you can plan where and when to plant your next pawpaw grove. Cheap bare-root seedling trees will save you money, but they won’t earn you money or appreciative friends. Premium fruit comes from premium trees, well cared-for.

Pawpaw trees can mature at 20ft tall, or you can keep them pruned to be 7-15ft and avoid high ladder work. The diameter of a mature tree can be 20ft in full sun, with an attractive pyramid shape.

Peaceful Heritage Nursery,

When planning your orchard site, remember “the more sun, the more fruit”. 12-14 hours is best, but 7-8 hours of direct, strong, undiluted sunlight will be enough for a decent fruit set. Pawpaws are not too exacting about soil, apart from the need for good drainage. Soil can be improved, but heavy wet soils need improving years before planting!

If you plan to mow with a tractor, you’ll need to plant rows 18-20ft apart. Otherwise 15-18ft between rows and 8-12ft between trees in the row will be enough. You do need genetically different trees close enough to cross-pollinate.

There are three colors of fruit: yellow, orange and white, with the orange ones having the strongest flavors (“banana/honey/persimmon/pumpkin”). Yellow-fleshed cultivars have more of a “banana/cocoa butter/Mexican flan/nutty/marshmallow/caramel flavor”, very sweet, with an aroma of citrus, pineapple, cantaloupe and strawberry. The white-fleshed ones are the mildest, with a “vanilla/light banana/cantaloupe/coconut/tropical fruit” flavor and a high sugar content.

Pawpaw fruit should be creamy, not watery or hard. There should not be any bitter or unpleasant after-taste! Another feature to consider when choosing varieties is the seed-to-pulp ratio. Ideally the seeds will comprise less than 10% of the total weight. Wild pawpaws can be 50% to 75% seeds.

Blake includes 57 pages of good, bad and interesting facets of all 50 cultivars he could find in 2020. Some are widely available, others need to be tracked down through the North American Pawpaw Growers Association (NAPGA) or the North American Fruit Explorers (NAFEX). Don’t rely on nursery descriptions, but use Blake’s notes, where he has worked hard to be fair and objective. This book costs less than one tree, and can save many mistakes!

Blake distinguishes between Early Ripening (Aug 20-Sept 5), Mid-Season (Sept 5-30) and Late Season (after Oct 1). The dates are for zones 5b-6b, and outside that area they offer a relative idea. There is a grading scale (incorporating different professional opinions) based on size, flavor, texture, reliability and yield. Choose As and Bs unless you have a good reason to do otherwise. Size grades are Jumbo (16oz+), Large (12-16oz), Medium (7-12oz) and Small (3-6oz). Commercial growers don’t mess with the little ones.

A matter to face with pawpaws is that eating under-ripe ones can cause nausea. Some people cannot tolerate cooked pawpaw, Some speculate that it is the combination of cooked pawpaw with grains (as in baked goods) that give them trouble. Be ready for these possibilities but do not let them discourage you (or potential customers!) There are also people who sometimes experience mild euphoria after eating pawpaws, without harm. The one thing to never make or consume, is pawpaw fruit leather! It can cause 24 hours of serious intestinal distress. This is the “warts and all” part of the book. Avoid these problems and enjoy everything else about pawpaws.

Thinking how to incorporate pawpaws into your diverse farming? You do need to keep the grass and weeds down somehow. Grazing, mowing or mulching are the usual methods. In damp eastern regions, mowing will need to be done once a month from April to October. Mulch needs to follow the 3:3:3 rule: 3ins deep, 3ft wide around each tree, keeping 3ins away from the trunk. Cardboard topped with organic mulch is one option. Landscape fabric is another. Wood or bark chips can work well.

Blake tells cautionary tales about planting a new pawpaw orchard and not providing irrigation. Climate change is making rainfall more erratic and we get both extremes of quantity.  There is no substitute for water in a drought, so install an irrigation system before you plant, or immediately afterwards. Once the orchard is established, you might not need to water much.  Blake recommends orchard tubing with two emitters per tree, providing a gallon of water per tree per day.

Pawpaws go dormant in winter, unlike some other fruits that can be planted in the fall in milder climates. Plant in spring or early summer, digging large holes, breaking up the edges of the hole, supplying amendments, and having mulch on hand. This book gives clear step-by-step instructions. Staked tree protectors are essential for trees shorter than 30ins (seedlings) or 18ins (grafted trees). One main purpose is to protect the young trees from UV radiation. Tubex and Blue-X tree shelters are suggested.

While the trees are young, you can use the aisles for something else, such as grazing, or growing hay or another crop. Whichever weed control method you use, you will need to hand weed the small inner circles around each tree, including clipping suckers coming up from the rootstock. This gives you an opportunity to study each tree up close and see how it’s doing.

The pests and diseases chapter is complemented by color photos. With pawpaws, there is still much that is not known (or was known and then lost). Insects that attack pawpaws do not usually do much damage, although the list is long and includes borers, stinging caterpillars, a webworm, a leaf roller, the ubiquitous Japanese beetle, slugs, snails aphids, mites, thrips, scale insects and the Zebra Swallowtail Butterfly.  Jeremy Lowe at VSU has a very good PowerPoint presentation with superb photos.

I have been fascinated by the ZSB since reading about it in Michael Judd’s book, where I learned that the butterflies arrive at the time the pawpaws flower. Since then, I’m on the lookout each spring. The pawpaw is the ZSB’s only host, so do not kill all their caterpillars in your pawpaw trees – they have nowhere else to live! The eggs are laid between June and August. The caterpillars, which grow to 2ins long, eat the leaves and the damage to young trees is a real concern. Blake recommends hand-picking the caterpillars and carrying them to a wild pawpaw patch, or to some mature cultivated pawpaws, where they do little damage. Also, avoid destroying nearby wasp nests as the Ichneumon wasp Trogus pennator is a predator of the caterpillars, and nature may balance out.

For many pests and diseases, the key to healthy trees is good sanitation, keeping a clean orchard floor (mulched or mowed, I don’t mean bare soil!), and removing diseased wood or leaves.

Deer bite off buds and young shoots, and rub their antlers on the trunks. Goats do not eat pawpaw trees, although they can do damage rubbing their horns against the trunks. Other large pests include raccoons, possums, small rodents, and sapsuckers (small woodpeckers).

Diseases include Phyllosticta leaf spot, a fungal pathogen., and a few others, including Black Spot (Diplocarpon spp) which strikes in rainy seasons.

The condition of the leaves will show you if your fertility program is adequate. Healthy leaves are a deep vibrant green and bigger than human hands. Young trees should make 16-24ins of growth each year after the first one, until they are mature. Fertilize heavily from March-June in zone 6.

The chapter on flowering stages and cold tolerance of each (information that is hard to find elsewhere) will save you from disappointment. See the helpful photos showing blossom stages. Unlike some tree fruits (apples, pears), pawpaws bloom over a period of time, resulting in flowers at different stages, giving insurance against all being killed by one frost. In zone 6 the very cold-hardy Velvet Bud stage, when fruit buds start to develop, is in mid-February and full bloom starts in early April.

Pollination is conducted by various flies, beetles including lady bugs and ants, and spiders. Not by bees. So for good pollination, plant insect-attracting flowers in your orchard. Fruit takes 4-7 months to mature.

Pawpaw trees begin to fruit in year 3-5, with 5-10lbs/tree and double that the next year. A mature tree will yield a bushel (30-40lbs). Harvesting needs to be done gently (no vigorous tree-shaking!). Use sharp bypass pruners and set the fruit in a single layer in cushioned boxes. Ship immediately or use refrigerated storage for a couple of days. If picked ripe but firm, pawpaws can be stored for 3-4 weeks under refrigeration. They won’t be as delicious as tree-ripened fruits.

You can sell pawpaws at 2-3 times the price of apples, maybe $5-10/lb. Because the demand is not widespread, do not rely on farmers’ markets. The marketing chapter suggests 8 channels for selling pawpaw fruit. You will need to provide information and an attractive display or stunning photos if selling online. Avoid the question “What do we do now with a hundred or even thousands of pounds of soft, dripping ripe pawpaw fruit?” by planning months or years ahead.

If selling remotely, make it really clear that pawpaws are only available to ship in August and September (or whatever is true in your region). Ship out only perfect unblemished fruit picked that same day, and ship only Monday-Thursday. Weekend shipping can go very wrong! Pack the fruit with enough lightweight packing material so that when you shake the box, nothing moves. (I learned this tip packing garlic for shipping.) Shipping fruit across the country is a strange business with a large carbon footprint. Consider if you have better options selling locally, including specialty groceries.

Sales to restaurants can work well, as long as you have clear agreements, including price ($1-$3 per pound). Be perfectly reliable, make the chef’s life as easy as possible. Deliver early rather than late if you can’t be on time.

One feature of modern pawpaw marketing is that currently most Americans prefer crunchy fruit (even crunchy peaches) and the pawpaw is far from crunchy. Describing the texture as similar to creamy avocados, but sweet, seems a promising approach.

You could sell fruit as frozen pulp (deseeded!) to restaurants, bakeries or breweries. You could make value-added products from the less-than-perfect fruit yourself. As well as the items mentioned earlier, don’t overlook the possibilities of ice cream, chutney, food supplement pills and jewelry made form pawpaw seeds. Find out about the Cottage Food Laws in your state. Blake recommends the Ohio Pawpaw Growers Association with 29 handouts about NA Pawpaws.

Aside from selling fruit, you could sell seeds, seedlings or grafted potted trees. Seedling trees can be unpredictable, but if you start with good parents, you improve the chance of getting good seedlings. You can use seedlings as rootstock for grafting, or sell them to people growing food forests where productivity is not the main concern.

Seeds removed from ripe fruits need to be washed, cleaned, sterilized, labeled, stratified at 35-45˚F for 90-120 days, ensuring they don’t freeze. Seeds are sown on their sides, and can take 6-12 weeks to emerge above the soil. 2-3 year-old seedlings are used for grafting rootstock. Grafting is fairly easy, and KSU has some very good free videos.

The book includes a pawpaw calendar, cost analysis and some troubleshooting. Tips include not to worry if your new trees only grow a few inches the first year. This is probably because growth is happening underground, establishing strong roots. It could be a sign of root damage during transplanting, so if you are about to plant more, improve your technique! Damage caused by sunburn, dehydration, nutritional shortages, attacks by beetles, sapsuckers, string-trimmers, Phyllosticta disease, borers, deer, and winter sun, are all covered.

The cost analysis deals with start-up costs (not minor when trees cost $30 each). For an acre containing 295 trees that’s $8,850. Tree protection fencing can add $1,376. Landscape fabric and irrigation together can equal the fencing cost.  Other smaller costs add in to a total close to $10, 700 for the acre. Try for a wholesale tree price between $15 and $25, and your total is more like $6,260.

Production costs are estimated by KSU at $1,650/acre; harvest and market costs at $6,200/acre, including labor for pruning and harvesting at $12.50/hr. Total variable costs come out at $8,400/acre. Gross returns could be $9,600/acre, if you sell wholesale at $1.75/pound. Don’t quit your day job yet, but pawpaws can be a good addition to an existing operation with compatible markets.

The two-page Pawpaw Orchard Calendar is a quick reference guide for annual maintenance, and the dates where you live may need to be as much as one month later in spring and one month earlier in fall. The resources section includes books, supplies, and groups, including Peaceful Heritage Nursery.

Blake has created a highly readable, enjoyable and very intensive exploration into the cultivation of North American pawpaw.” This book is practical, useful and fascinating.

Book Review: Whole Farm Management from Start-Up to Sustainability, Garry Stephenson

Book Review: Whole Farm Management from Start-Up to Sustainability,

edited by Garry Stephenson et al, Storey Publishers, 2019. 312 pages, 8” x 10” format, full color photos throughout, $26.95

This is an encouraging and inspiring practical resource for beginning farmers and those growing and maintaining a farm business. It uses examples drawn from twelve farms (16 farmers). Nine of the farms are in Oregon, with one each in Missouri, Pennsylvania, and Virginia. As for diversity, three of the twelve farms have people farming while black, one has an Asian-American family, and there is a range of family relationships, including single farmers. What this book is not: how to grow lettuce, how to practice rotational grazing, how to slaughter chickens, how to prune apple trees.

Whole Farm Management is based on the curriculum from the Center for Small Farms & Community Food Systems at Oregon State University. The course is available online, and focuses on small-scale organic and sustainable agriculture through the Extension Service Small Farms Program. Royalties from book sales will support OSU beginning farmer education.

“Operating a farm business requires managing dreams, crops, people, markets, money and reality.” Whole Farm Management blends advice and inspiration from experienced farmers with guidance from ag educators. Recognizing the Manage/Learn/Succeed cycle, one of the farmers advises “You can’t know it all at once. Growing is where it starts. You have to know you can grow something before you can figure out how to sell it. But once you grow it, you have to figure out how to market. And once you’ve sold a few things, then you’re in a position to ask: can I afford to keep doing this?”

The first one to three years of farming are about proving we can grow and sell. The next couple of years are more deliberate, less frantic. The next few years focus on how to make money. After that the question becomes “We can. Should we?” In terms of using the book, if you are in the first few years of farming, you know you can’t learn everything at once. You grab onto the bits of information you know you need. You skip over the things you don’t see an immediate need for. Learning is endless. How do you define success? Success can include the elements of social, operational, lifestyle and financial well-being.

The book follows the logical progression of training used in the OSU Growing Farms program and we can all benefit from following their well-traveled ten-year path. One or two individual farms are introduced in each chapter to illustrate particular points or aspects and the photos draw us in. There are six sections, each opening with a list of what you’ll be able to do after reading that chapter:

  1. Dream It – Strategic Planning. (Values, vision, mission; assessing your resources and needs; creating a foundation that matches your plan with your resources.)
  2. Do It – Farm Infrastructure, Labor and Energy. (How to put your resources – equipment, infrastructure, people, processes – to work.)
  3. Sell It – Markets and Marketing. (Developing a marketing strategy in line with your farm values, vision, mission before deciding what you will grow or raise.)
  4. Manage It – Business Management for the Farm. (Learning to be successful.)
  5. Grow It – Managing the Whole Farm Ecosystem. (Understanding the big picture and the basic principles and practices of sustainable agriculture.)
  6. Keep It – Entrepreneurship, Family Business Dynamics, and Managing Risk. (Planning for the long haul.)

These chapters are followed by appendices with 23 worksheets (also available online from Storey Publishers) and resources.

The arrangement of the book facilitates the learning style/stages the editor recognizes as the real way people learn. This is a book to browse initially, reading the farm profiles to get inspiration, and then return to more methodically learn specific information and skills, using the text and the worksheets. Thus fortified, you’ll be ready to assess what you need to focus on learning next. By clarifying priorities and direction, this approach helps avoid panic and the feeling of being over-whelmed.

In chapter 2 six of the farmers share their experiences about essential equipment and infrastructure, to help new farmers make a shopping list. Here is information about different systems of irrigation (although biased towards methods for Western soils). In Oregon, you can’t farm without Water Rights. For Easterners, it can be hard to understand, as can using glacier water, snow melt or getting only 9” of rain a year. I got lost on the explanation of water drawdown and pressure head requirements. A case of skimming or skipping what you don’t need to know!

In the chapter on Markets and Marketing, six of the farms discuss aspects such as envisioning the market that will meet your needs, overcoming challenges, keeping your focus on values and goals, listening to customers, adapting a CSA model, and evolving marketing strategies over time. This chapter also looks at agritourism, u-pick, farm stands, wholesale and retail markets, and pricing.

Business Management will be vital, sooner or later in your journey. It is a process of continuous learning, continuous improvement. Here is a four-part cycle of planning and setting financial goals; implementing your plan; keeping records; assessing and analyzing your season, then round to more planning. If you want to earn your living from farming, here’s the help you might need. Consider expenses as well as sales, understand depreciation, calculate your profit (your earnings). Remember to include your management overhead time, such as making a new To Do List. Find out if it’s a better use of your time to make hay or buy it. Plan your cash flow month-by-month over the whole year, to make sure there are no avoidable dips into the red. Learn various ways farmers manage cash flow and get loans when needed. Here’s help choosing an accounting system and a record-keeping method. Here are explanations of all the accounting terms that might have left you with a sinking feeling. As Melanie Kuegler of Blue Fox farm says in closing the chapter, “So our highest value is making sure that we’re all taken care of while producing good product for people.”

Chapter 5 on Managing the Whole Farm Ecosystem starts by reviewing the key elements needed to create a successful farm business. This chapter helps you see the whole woodland, not just the trees. Here we look at planning, and contrast that with intervention (what you do when the plan doesn’t work out). For example, in sustainable pest control, the planning might include ways to create healthy crops/livestock to resist pests; making it difficult for pests to settle in and reproduce; boosting populations of beneficial organisms. Intervention includes what you do when pest problems happen. The best interventions include adjusting your plans for the future to avoid that problem. This chapter includes cycles of energy flow, nitrogen, carbon, water, all to help us come up with strong integrated production strategies. Reading the accounts of how various farmers dealt with problems and adjusted their plan contains food for thought for all of us.

The last chapter is guidance on keeping the farm over the long haul. Risk Management is exactly as it sounds. In farming there is always risk. There are so many variables, and some of them we don’t control. We seek the serenity to accept the things we cannot change, courage to change the things we can, and the wisdom to know the difference, as Reinhold Niebuhr’s Serenity prayer puts it. Also the skill to mitigate the impact of things we cannot control but may be able to change a bit. This chapter helps us understand business opportunities, legal requirements and options, and the challenges and rewards of farming. It helps us identify steps to address risk. Several business structures are compared, along with possible interpersonal dynamics. Planning for the long term future includes handing on the farm to the next farmers, whether those are family members or not. Licenses and certifications need to be attended to, and the farmers in this book explain how they tackle those regulations and use them to distinguish the quality of their business and farm products.

The text ends with a short section of challenges and advice from seven of the farms. Staying sane by separating farm work life from non-work life; avoiding burnout by having enough workers that no-one over-does it; taking a day off each week; giving some attention to the health of the farmers as well as the soil, crops and livestock; being really clear about why you are choosing this life; accepting results that are good enough rather than being a perfectionist; distinguishing your farm by doing something superb and/or unusual; paying attention, studying and reading, talking with more experienced farmers; enjoying the sense of satisfaction and pride.

Whole Farm Management is a valuable book to make farming sustainable for the farmers, who can then provide good food for people, and contribute to a better world.

Book Review: Grow Your Soil! by Diane Miessler

Book Review: Grow Your Soil! by Diane Miessler

Harness the Power of Microbes to Create Your Best Garden Ever

Storey Publishing, January 2020

  • Price: $16.95
  • Size: 6 x 9
  • Pages: 176
  • Format: Paperback ISBN: 9781635862072
  • Other formats: Ebook

Grow Your Soil! is an introduction to soil biology and gardening in eight chapters. It is written as if describing how to build a house (but starting with the roof!). Diane Miessler writes in plain English, with a light style, and her book has the endorsement of Elaine Ingham, who writes the foreword, saying that Diane’s humor and tongue-in-cheek joy make this book a joy to read. People were once told that using inorganic fertilizers and pesticides was the only way to grow enough food for a starving world. Elaine simply states “That was a flat-out lie.”

Diane’s encouragement to garden in partnership with the soil food web lists the many benefits of a healthy environment, healthy flavorful food, and the satisfaction of doing what you believe is right. She has a ten-point list of suggestions for creating healthy living soil using no-till systems, lots of mulches, home-grown fertilizers, and by encouraging biodiversity. The fundamentals of soil science are explained – soil is about 45% minerals (sand, silt and clay), 20-30% air, 20-30% water and 5-10% organic matter. A teaspoon of good soil contains more microbes than there are people in the US, more species than all the vertebrates on Earth, several yards of fungal hyphae, a few thousand protozoa and several dozen nematodes (mostly good ones). Soil is our planet’s third largest carbon sink (after the oceans and fossil fuels). Healthy soil is continually pulling carbon dioxide from the air and sequestering it in the organic matter and humus. We want to have as much sequestered carbon as possible, both to reduce the amount in the atmosphere and so that we can use it to grow food.

 Diane’s mulch recommendations are to generally aim for a mix of one-third green matter (which feeds bacteria) and two-thirds brown (which feeds fungi), but steering towards more green matter for annual vegetables, more brown for woody perennials, in line with the predominant life-form each type of crop does best with.

The cover crops section first describes the plants, then how and when to use them. I had a brief worry that people would go out and plant buckwheat or sweet potatoes in winter, until I read on! In fact, Diane does suggest you can sow buckwheat whenever you like, and it will be dormant until the right spring weather occurs. In our central Virginia climate this does not work. Buckwheat seed rots in cold wet soil. Buckwheat can germinate in a warm early spring spell and be struck down by a following frost before it has made much growth at all. As always, it pays to discuss ideas you haven’t tried before with nearby gardeners.

This book has a good basic description of the Soil Food Web, for new gardeners or anyone who is a bit mystified about what’s happening in the soil. And for those over 50 whose biology classes only included the two plant and animal “kingdoms”, here are explanations of the classes of bacteria, fungi and archaea, the main types of soil microbes. Archaea are neither bacteria nor eukaryotes (tiny organisms that have their DNA in a nucleus). Archaea are similar to eukaryotes in some ways, but have more resistance to extreme conditions. In the soil they work as decomposers.

Next up are the algae, protozoa and nematodes. The algae spectrum goes from one-celled photosynthesizing life-forms to giant kelp. In the soil they provide nutrients and increase plant resistance to diseases. Protozoa are one-celled animals, which release excess nutrients from their meals of bacteria and fungi, in a plant-available form. They help balance the numbers of bacteria in the soil. Nematodes are (mostly) microscopic roundworms that are mostly benign, from our perspective, and healthy populations keep the destructive nematodes in check. Arthropods (including insects, spiders, mites, ticks and scorpions) are shredders of organic matter in the soil (while eating smaller life-forms).

Bigger soil-dwellers include worms, slugs, snails, and small mammals. By the way, Diane explodes the myth that coffee grounds can control slugs, and claims to have videos to prove it untrue. And she tells us that fence lizards eat harlequin bugs. (I think she lives in California). Western fence lizards are centered in California, and according to the National Wildlife Federation, Eastern fence lizards are found between New York and northern Florida and as far west as Ohio and Arkansas. I want some!

The next section of the book explains Cation Exchange Capacity (CEC), a measure of how many positively charged ions (cations, nutrients like Mg, K, Ca, ammonium) can be held by the negatively charge soil particles. Diane likens this to the pantry. Soils with a low CEC can’t hold many cations, and the key to increasing the CEC is to increase the soil organic matter content. Clay soils may have a high CEC, but the nutrients may be held too tightly to be useful to plants. The solution to this problem is also to increase the soil organic matter content.

Diane offers several ways to increase the organic matter, and one of her favorites is biochar. Biochar in its original form is more or less sterile, not nutritious at all, but in the soil it can act like humus on steroids – it is very good at absorbing water, hosting microbes, reducing plant diseases and lasting a long time in the soil. I have been skeptical about some of the claims for biochar, and of the net gains in reducing global heating. Diane does not make any wild claims (she’s not selling the stuff). She is open about the fact that the mechanism for suppressing disease is not yet understood.

As I said, Diane is not selling biochar. In fact she describes how to make your own on a small scale with an “upside-down” outdoor fire (with all due safety precautions). Big pieces of wood are arranged on the ground in an open airy stack, and a small fire is lit on top with tinder and kindling. This means the fire produces little smoke (all smoke is air pollution). The fire is thoroughly doused with water once everything is glowing but not flaming. Those wanting to make biochar on a bigger scale are referred to a double-barrel biochar burner on YouTube.

Diane Miessler

The next section is on photosynthesis, minerals and soil testing. Diane describes the effects of too much, too little and just right amounts of the main soil nutrients first. A deficiency of phosphorus shows up as blue-purple colors on the older leaves. She doesn’t mention phosphorus surplus, although she does confirm that excess phosphorus added to the soil will usually be locked up and become inaccessible to plants. Potassium deficiency can cause yellow leaf edges. Next up are other macro-nutrients, such as Calcium, magnesium and sulfur. Calcium deficiency leads to stunted new growth, brown around the edges, perhaps with yellowing between the veins. Bulb and fruit formation can be damaged, as with blossom end rot of tomatoes, caused by insufficient calcium reaching the fruits. By contrast, a magnesium deficiency leads to older leaves becoming yellow between the veins and around the edges, perhaps with purple, reddish or brownish discoloration. Sulfur shortage can lead to “unthrifty” plants. Shortages of any of these can be remedied by the addition of more organic matter.

Micronutrient shortages can also be helped by organic matter, although in Virginia I have noticed that we do sometimes need to add boron on its own (in tiny amounts).

Diane describes how to test soil, understand the results, and remedy the situation. Try adding organic matter first, and only tinker with the specifics if the general remedy is not enough. For instance, if your soil biological activity is low, you may find that piling on organic matter doesn’t help. Use compost to add  some more life to the soil and get a better balance of diners to dinners. There is a helpful one-page “Order of Operations for Fixing Soil”: Correct the pH; correct the calcium level; correct any excesses (usually by adding gypsum); correct the macronutrient deficiencies and lastly correct the micronutrient and trace element deficiencies. Clear instructions like this are so valuable to newer gardeners!

There is a chapter on making compost and compost tea. She suggests thinking of compost as a sourdough starter, and mulch as the flour. Both are valuable, and they work well together. Making good compost is a valuable skill to learn. Try for the a good balance of high nitrogen materials and high carbon materials, with enough water. Turn the pile, assess its progress, add what it seems to need. Rinse and repeat. Diane recommends against spending money on fancy compost bins. “Compost needs love, not a container.” There is value in turning the pile and seeing how it’s doing. If it’s fully enclosed in a tumbler, you might miss the signs that it needs a specific kind of care. Here is encouragement to learn the art and science of compost making.

Worm bins are a great way to use kitchen scraps to produce worms and compost, especially in winter, as worm bins need to be in a non-freezing place to stay alive. I disagree with Diane about using the liquid leaching from the bottom of the bin as a “compost tea” See my review of The Worm Farmer’s Handbook by Rhonda Sherman. This liquid might not be good for your plants. To make compost tea, put some of the wormcastings in water and bubble air though it. Instructions are in Diane’s book a few pages later.

Another small industrious worker is the black soldier fly. The (harmless) maggots of these (harmless) flies will out-compete other (disease-carrying and/or biting) flies in eating up kitchen scraps in an odorless way. They are also a favorite food of poultry, and there are clever ways of setting up a bsf bin so that the pupal stage will “self-harvest” by walking up a ramp and dropping into a collecting box. See YouTube for all the details.

After explaining these various aspects of growing good soil, Diane pulls everything together into a chapter on Building a Garden That Feeds Itself. Here you can learn about sprinkler irrigation,  mulching, planting, and selecting good tools. The next chapter covers being a good neighbor, by having a good-looking, good-smelling, productive garden that gets frequent attention. Diane advocates for pulling weeds and dropping them on the bed, without worrying about weed seeds or plant diseases. I can see this would work best in a smaller garden where things don’t get out of control, and in drier climates with fewer diseases and less chance for weeds to re-root. There’s a panel about roses that I didn’t read. (Roses are a great trap crop for Japanese beetles; I’m not a flower grower!)  A big help to beginners is the glossary at the end, and the bibliography of books on soil life.

If you are a beginner organic gardener, or you’re looking for a book for someone in that category, this book has a clear user-friendly approach. It won’t scare off newbies with too much detail.

Book Review: Will Bonsall’s Essential Guide to Radical, Self-Reliant Gardening

Book Review: Will Bonsall’s Essential Guide to Radical, Self-Reliant Gardening. Innovative Techniques for Growing Vegetables, Grains, and Perennial Food Crops with Minimal Fossil Fuel and Animal Inputs. Chelsea Green, 2015

In 1971, Will Bonsall went back to the land in Maine, with his wife, Molly Thorkildsen, and their two sons. They built the farm over the course of five years, “one foundation stone and one exquisitely harvested and finished piece of wood at a time. As neat and efficient as a ship’s cabin, Khadighar Farm rises up on a hillock in the midst of 85 acres.” (Press Herald 2014). Will Bonsall runs the Scatterseed Project, (as featured in the documentary “Seed: The Untold Story“), an organization for the collection, preservation and sharing of seeds. Jim Gerritson, in his endorsement says “The risk of describing [this book] as a gardening book is that the aspiring reader may miss the reality that it is really a book on life, centered as a good life should be, around a garden.”

Will Bonsall’s gardening (life) is focused on Veganism and Eco-efficiency, looking deeply into replenishing the soil by considering each organism’s intrinsic energy as a food in proportion to the food energy (or soil fertility) required to produce it. Only photosynthetic plants actually produce a net increase over the soil-derived nutrients they consume. All animals have a negative ratio. This is not to say all livestock are bad (or for that matter, that people are bad). Different animals vary in their Eco-efficiency and different terrains respond to different treatment. As the author says, you can pick and choose from the ideas presented, without needing to agree 100% with his ideology. And before anyone imagines that Will Bonsall advocates isolationist self-sufficiency, note that he points out that the most stable solutions for hard times involve cooperative, collective, community action.

The book starts with building soil fertility, moves on to growing and saving seeds and propagating plants, then discusses growing particular crops (vegetables, grains, pulses, oil seeds, and “permacrops”. Part 4 explains how these strategies are integrated to make best use of the land, and how to deal with pests and diseases. The book closes with some ideas for using and preserving the foods grown. As with all agriculture, there is not a linear progression of topics, but a network of ideas.

The bottom line on soil fertility is that how we balance the efficiencies of tilth-building imports will determine the long-term sustainability of our farm (and our planet). What are the true costs of bringing in soil-building materials? Here are good instructions on making compost, from the variable ingredients you are likely to have. Will uses 900 pounds (408.2 kg) per 180 ft2 (16.7m2). For some time I’ve been curious about how much compost other growers use. We use about 46 gals/100 ft2 in our hoophouse. Most other professional compost-using growers who I know of use 12-40 gals/100 ft2. How to compare weights with volumes? Perhaps 3.5 lbs/gal? At that density, Will’s rate is 143 gals/100 ft2. It does look very generous in the photo, but perhaps I have miscalculated. He does not report excess phosphorus in his soil, which is one of the main concerns about using lots of compost. Because he commends buckwheat as a cover crop for making soil phosphorus available to plants, I deduce he doesn’t have a surplus. Perhaps the relatively closed nutrient system on his farm reduces the potential problem. Perhaps it is the lack of animal manure.

Among other cover crops discussed here, sweet clover comes out well, for tolerating sodium, making deep roots, fixing nitrogen and bringing up more phosphorus. And growing so tall it can be mowed and the top growth taken for compost-making. Alfalfa has similar features, but is not so cold-hardy. (Khadighar Farm is in Maine.)

While Will’s farm is veganic agriculture, he is still a grass farmer. He uses wood ash and ramial wood-chips (chipped small branches and brush) to improve his grassland, reckoning this more sustainable than farming cattle.

Will describes chopping out circles of cover crop to transplant squash into, as a way of extending the valuable life of the cover crop until the last minute. I’d caution southern growers about trying that. When squash grow fast they can quickly run over cover crops and make life difficult. I tried winter squash with buckwheat once and the crew never quite forgave me, as we had to wade in and pull up the buckwheat to prevent seeding.

I was very interested to read that his squash plants, having grown surrounded by oats and peas (flattened and covered with tree leaves) never get troubled by striped cucumber beetles (one of our more pesky pests). Ramial wood chips are a great way to build soil, if spread on the surface rather than turned in. Fungi will break down the material overtime. The key is to get the woody material locally, to be eco-efficient. We ask our electric co-op to unload their line-clearance chips near the end of our driveway.

Because importing minerals and other soil builders over large distances is not sustainable, it is wise to conserve minerals and recycle those nutrients on your own land as long as possible. Humanure is worth considering, if you are not selling Organically-Certified produce to others, as long as you can be sure it doesn’t have medications or diseases in it, and you are quite choosy about which crops you apply it to.

Will says “boron is most vulnerable to erosion via the marketplace”, meaning selling produce can deplete your soils of some minerals.

Woodash is a valuable resource (although I reckon southern growers get less wood ash than northern growers).Wood ash can help reduce soil acidity, but probably don’t apply more than 10-15 lbs/1000ft2 (4.5-6.8 kg/92.9m2).

The second section of the book is about understanding annual, biennial and perennial plants and how to propagate them by farming seeds, and storing them well to keep them viable. He doesn’t just work with open-pollinated varieties. He points out that some hybrids don’t contain much genetic diversity, “a detail no one wants you to know”. Many hybrid tomatoes will grow surprisingly true to type, as the parent lines are not very divergent to begin with. He suggests Sungold tomato as one example.

Next he explains various ways to clone plants (replicate them asexually) via suckers, layering, cuttings, grafting. I just learned that blood, sweat and tears are bad for grafting, as the cambium cells will be ruined!

The third section of the book (150 pages) is about various crops. These are divided into vegetables, grains, pulses, oilseeds and permacrops. Will Bonsall is, after all, aiming to grow a complete vegan diet. In the vegetables chapter, Will focuses on areas where he has a unique approach, or at least one not widely known about.

There is a valuable tip about not planting peas too early. Plant a week later, when the soil is warmer, and your harvest will start a few days later (not a full week later) than it would have, and more importantly, the yield will be higher. Early lettuce or Egyptian onions make good space-sharing companions with fava beans. Rather than pine because they are too far north to grow lima beans, the family grows white-seeded runner beans (Phaseolus coccineus) to use as dry beans. I loved runner beans as a green bean in England and here I learn that many white runner beans have names with the word “Lima” in them. Confused? No wonder!

I might follow Will’s tip and grow only Early Jersey Wakefield, Danish Ballhead and a red storage cabbage. I’ve spent years seeking the perfect combination of cabbages for early eating, storage and sauerkraut. Perhaps this is it? I like the EJW well enough already, although I also like the hybrid Faroa. A trick Will has for getting best use of space is to plant the EJW at 18” (45 cm) spacing, with kohlrabi transplants in between. The kohlrabi are harvested first, leaving space for the cabbage to reach its (small) full size. Lettuce is another option.

It’s always gratifying to read another garden author advocating for something we do too (bare-root transplants). He has details for growing your own bulb onion sets from a mid-July sowing (in NY). The keys to success include sowing thickly in very rich soil, and finding the right variety, as well as the right date – early enough to grow a plant bigger than a wispy seedling, but late enough so they can’t move straight into making seed heads the next spring when replanted. The plants need to die back and harden off for storage. It takes skill!

I’m going to look out for Chinese broccoli (B. oleracea var. alboglabra), Bonnie Best and Siletz early determinate tomatoes, yellow-fleshed potatoes (especially Granola) and Baxter OP sweet corn.

I appreciated reading Will’s explanation of the causes of the Irish Potato Famine. Food justice is as important as good gardening skills. Let’s stop blaming Late Blight (Phytophthera infestans) and look instead at the English landowners shipping out wheat, barley and beef, reducing their peasant workers to a diet of potatoes and dairy products, which (although very unjust) was adequate as long as the supply of milk lasted and until the reliance on a single variety of potato (Lumpers) brought them to starvation and desperation.

I just learned that cucumbers are rich in soluble silica, important for healthy teeth. Will describes this silica-dissolving property as “eating rocks”!

It’s often said how it’s hard to judge the mood behind someone’s email – are they angry? Tired and grumpy? Making a joke? Sometimes I was left wondering at some passages in this book. He starts one story out by mentioning his “patronizing chuckle” at his wife Molly’s suggestion of mulching their grain plots, follows it up with telling how well it worked when he did try it and how he always mulches grains now. He ends the paragraph with “Yep, I’m totally convinced that’s one of the best ideas I’ve ever had,” but I have to give him the benefit of my doubt. He’s sailing close to obnoxious realities that most women have had to endure.

I appreciated the section on the types of millet. I’ve often been confused about the different types and how best to use them as cover crops. Naturally, I need my “climate zone glasses” on – Virginia has different weather from New York, and what’s true there is not necessarily true here.

Japanese millet – not frost hardy, not suitable for human food (tight hulls)

Proso millet – not frost hardy, short, early maturing, not much biomass, loose-hulled. All are very attractive to birds once seeds form.

For those wanting to venture into small-scale grain-raising, this book has the basics for wheat, triticale, barley, oats, rye, millet, rice, field corn, buckwheat, amaranth and quinoa.

Pulses are dry peas, beans, lentils and other legumes. Not many books have the detailed information found here.

The oilseed chapter proposes the less usual idea of using the ground oily seeds in food, rather than extracting the oil from the seeds, adding it to cooking, and then dealing with a byproduct. I have not read much on this subject since I reviewed Cindy Conner’s book, Grow a Sustainable Diet. In this chapter, Will discusses sunflowers, pepitas, flax, poppies, hazelnuts and some experimental crops. In their climate, peanuts, olives, oil palm, safflower and sesame won’t mature. They don’t grow rape/canola as a seed crop because they value it more as an early greens crop. I was fairly horrified to read that they are trying chufa (tiger nuts) because we have serious weed problems with both yellow and purple nut sedge, also known as chufa. Will says that this food crop is not invasive, and will die with the frosts. I’m not going to try that in Virginia in case it hybridizes with the weed kinds – that would be too terrible!

The “permacrops” are tree nuts like chestnuts, hazels, acorns, pea-shrub and honeylocust, and tree fruits, cane fruits, blueberries, hardy kiwis, autumn olive (invasive in Virginia), dogwood cherry (cornelian cherry), rose-hips, ribes, apples, plums, pears, medlars, mulberries. Then there are the non-woody permacrops such as Jerusalem artichokes (terrasols) and apios. I’d never heard of those – they are groundnuts (but not peanuts), and they can get invasive. Various minor tuberous crops are discussed, such as cattails, Chinese yams, crosnes, daylilies and nanny-berries (wild viburnum).

The fourth section is “The Garden in Context” (Rocks, water, land; pests and diseases; and “smaller footprints” – ways of increasing yields from a given space). There are clear instructions on digging trenches to drain overly wet areas. I am still unclear though, on how big (deep, wide) drains need to be if you fill them with rocks. When I was doing calculations for our hoophouse, I concluded that the size of the drains if filled with rocks would have to be enormous, as most of the trench would be occupied by the rocks, leaving little room for the water. Obviously, the gradient of the ditch makes a difference too, as well as the quantity of water we’re talking about. Worth careful consideration before digging! I like Will’s drawing of a stone culvert in the bottom of the trench, to preserve some open space for the water to run in.

As for increasing yields from a given area, Will clarifies the differences between Old World agriculture (many crops, methods, tools, livestock shared across a large area) and New World agriculture (more isolated, fewer crops (mostly frost-tender annuals), cultivation mostly in the lowlands, no plows, no livestock, mostly slash and burn cultivation with long crop rotations). Old World crops lend themselves better to close planting, although the vining New World crops make better use of vertical space, and fit better with mulched no-till systems.

I appreciated Will’s take on companion planting – it’s not so much that different crops “like” each other, as that they have few quarrels. Peas grow up a trellis and spinach, chard, lettuce or carrots can occupy the rest of the bed without competing with the shallow-rooted peas. The carrots use all the nitrogen from the soil, while the peas are self-sufficient. Edamame can grow in the aisles between sweet corn rows – Will sows the edamame seeds in the same furrows as the corn seed. The corn yields normally, but the edamame yield is reduced by about 50% compared to growing it in separate rows. But the overall yield of corn-plus-edamame is greater for the space. Will has tried and true examples and pointers on factors to consider when designing your own combinations: timing, root depth, fertility requirements, access to light.

Will Bonsall

There is something inherently unnatural in any kind of farming.” “Chaos, change and instability are more the norm; the best we can do is exploit them to our temporary advantage.” We must deal with pests! Will’s recommendation is to haul all vegetable crop residues to a hot compost pile, even if no disease is apparent. And to practice serious crop rotations. Animal pests are a problem in inverse proportion to their size: big deer can be excluded. Flea beetles are a bigger problem. Will recommends brewing toxic rhubarb leaves, being careful not to have them anywhere near human food in a way that could cause lethal mistakes. Apply as a fine mist.

The last section is on using the harvest, including milling, baking, sprouting, freezing, fermenting and drying. I didn’t take so many notes on this section, but for those wanting to mill wheat and corn, make buckwheat noodles and bake breads, the info is there. Also for sprouting, malting, freezing, fermenting and dehydrating. Also using oilmeals rather than pressing oil

At the back of the book there are lists of recommended tools and resources and a few thoughts about energy use and alternative technology. This is an excellent book for those wanting to produce as much of their needs from the land as possible, and also for those who enjoy reading about quirky persevering hard-working folk who are doing just that, perhaps with an eye to inching in that direction themselves. Even relatively experienced growers will find something new in this collection of detailed information based on lived experience.

Book Review: Farming While Black, Leah Penniman

Farming While Black, Leah Penniman, Chelsea Green, November 2018

ISBN 978-1-60358-761-7, 368 pages, $34.95 Full color photos and illustrations throughout.

 

This timely book is Soul Fire Farm’s Practical Guide to Liberation on the Land. As Karen Washington says in the foreword, it “sheds light on the richness of Black Culture permeating throughout agriculture.” It’s practical, political, spiritual, uplifting and inspiring.

Before I go any further, I should say I’m white. I’m a farmer, a first generation immigrant, an enthusiastic reader of good farming books, and someone who likes to pass things she learns on to others. I love that this book brings farming wisdom from African and Caribbean cultures, gems like information on the susu Caribbean community mutual lending groups and inventive methods of farming with small material resources. I love that this book opens our eyes wider to the historical and current, shamefully unjust treatment of people of color as they farm. The title is perfect.

Leah Penniman is a Black Kreyol farmer who has been working as a farmer for 20 years and as an anti-racist food activist for 15 years, and a mother for some years too. She is a founder of the ten-person Soul Fire Farm in New York, which supplies low-cost healthy food to people living in places where they would otherwise be without good food. The farm offers training programs to Black, Latinx and Indigenous new farmers, as well as Black youth who would otherwise have received punitive court sentences, and anti-racism workshops.

Throughout the book are sidebars with the title “Uplift”, bringing wisdom from the African Diaspora. There are also tales from her own learning curve, such as letting the excitement over finding land blind her to the impoverished nature of the soil there, and the lack of road, electricity or even a house. She passes on to us her 13-point list of characteristics of suitable land, and her three essentials for farming: land, training and material resources. She knows the conventional resources, the unconventional ones, and how to tap into them. For instance, squatting land and activating an adverse possession claim after paying taxes for enough years, or making use of the National Incubator Farm Training Initiative programs.

As a result of decades of USDA discrimination and white injustice, the percentage of farms owned by Black farmers in the US has gone down from 14% in 1920 to less than 2% today. USDA is starting to make amends by offering some greater resources to “historically disadvantaged” farmers. There is a long way to go, to undo past harm. Land injustice continues today. Over 80% of food eaten in the US is grown by Latinx workers, but only 2% of farm managers are Latinx. A bright spot during the Great Depression was the formation of the Southern Tenant Farmers Union, an interracial organization that used nonviolent protest to demand their fair share of government support.

The Uplift sidebar about the New Communities Land Trust particularly interested me. This, the first community land trust in the US, was set up in 1969 as a 5,700 acre farm collective owned in common by Black farmers. Yes, they were shot at by some white neighbors, and suffered thefts. They were denied emergency drought relief in 1981-82, while white farmers received funds. In 1985 they had to fold and sell the land. In 1999 they settled a civil rights case for $1.2 billion and re-established on a 1,600 acre former plantation, renamed Resora.

This book contains many useful resources I have not found in such concentration elsewhere! Contact lists for farm training programs, and in particular, ones led by people of color, with an awareness of the political implications of white-led programs that ask people to work for no pay, doing work that benefits the landowner. She tells of some specific acts of reparation where a European-descent person with means transferred a portion of their land to the descendants of those who created the wealth. She encourages people of color to be specific in asking for reparations, suggesting “If you want advice, ask for money. If you want money, ask for advice.”

When it comes to asking for loans, many Black people do not have access to conventional credit because of the legacy of structural racism. Alternative resources such as susu are needed. These are microfinance membership groups that pool subscriptions and fund one member at a time. Leah Penniman offers models of financial sustainability that question capitalism and reinforce the understanding that land has belonged to people in common for much longer than it has been owned privately. Those who have known want don’t assume that the world owes them/us anything, and so will want to pay close attention to financial agreements.

Sharing work via the konbit system is another way for people to support each other to get timely tasks completed. Every farm gets the chance to receive the help as well as provide it. This book provides a great deal of help. In return, don’t look for the cheapest place to buy it! Pay the fair price, or even offer reparations if you are from a family that benefited from historical exploitation of people of color.

The book offers help with clarifying your mission and goals, and making a farm business plan. Soul Fire’s goals include training and empowering aspiring Black, Latinx and Indigenous growers and young people, providing healing, offering education in environmental justice, food sovereignty and other transformative justice, supplying good food locally at affordable prices, sharing their farming model, collaborating with other Black land justice networks and being a culture that cares for the well-being of its workers.

There’s a whole chapter on restoring degraded land, which Leah Penniman surely knows well, having started with soil listed as marginal and unsuitable for growing crops. She addresses remediating soils contaminated with lead, an especial problem in urban soils which are more likely to be available at lower prices, financially speaking. She shares specifics about Haitian farmers’ work to remediate the soils they inherited after colonialism, using vetiver perennial grass planted on contour to prevent further erosion. Leah Penniman gives step-by-step instructions on soil testing, chelating the lead (acidifying the soil), using specific plants for phyto-remediation, removing the mature plants for disposal as hazardous waste, and retesting your soil.

There are details of how to measure the slope on your land using only a line level and string. This is so you can mark contour lines and create terraces, plant fruit trees and stabilize the soil. There is a very clear description of using tarps to smother weeds without tillage. (I am so relieved we can now call this process “tarping” rather than the cumbersome “occultation”!) The Feeding the Soil chapter explains the difference between the “energy-drink” effect of chemical amendments and “nutritious-meal” amendment with compost, rock dusts or seaweed. Cation Exchange Capacity is beautifully explained with a hip-hop metaphor comparing the number of binding sites to the number of vocalists!

The Crop Planning chapter offers crops unusual in the US as well as staples. I was tickled to find Soul Fire Farm calls their high tunnel “North Carolina” because its microclimate is more like that state than New York. We called ours (in Virginia) Trinidad for similar reasons! I like the idea of using a piece of wire mesh (hardware cloth) on top of an open flat to help with seed spacing.

The Tools and Technology chapter gives advice for simple affordable hand-made equipment (such as worktables at the right height), and using fingers, knuckles, hand-spans and length of stride as measuring instruments that will always be with you. There is a one-page equipment checklist which includes a hammock for after-lunch siesta!

The chapter on seed-keeping tells of the 2013 success of the Haitian Peasant Movement G4 in winning the Global Food Sovereignty Prize for their rejection of a large donation of seeds from Monsanto despite the challenges caused by the huge 2010 earthquake. That takes courage as well as wisdom and long-term thinking.

Unlike most crop production books, this one includes chapters on raising livestock, plant medicine (with recipes), cooking and preserving, healing from trauma, building a movement and how white allies can be helpful in uprooting racism. There is also a chapter on Honoring the Spirits of the Land.

In the Urban Farming chapter we learn more about the Great Migration which pushed 6 million African Americans from the rural Southeast into the cities of the North, Midwest and West. They were moving away from lynching, land theft and other forms of racial violence, as well as share-cropping, loan discrimination and other unjust practices. By 1970, 80% of African Americans lived in cities. The National Housing Act of 1934 institutionalized housing discrimination, ranking Black neighborhoods (marked in red on the maps) too risky for mortgages. This led to lowering of property values, and decline of Black neighborhoods.  Veterans returning from World War II were entitled to zero-interest mortgages, but these were illegally denied to African American veterans. Sadly, white “pioneers” have co-opted urban farming in many African American neighborhoods, getting grants that were denied to the Black leaders of area improvements. This chapter provides information on starting and maintaining urban farms, all the way from finding land (look at tax maps of vacant lots, find the most recent owner, open negotiations), through navigating “nuisance ordinances”, making land-use agreements, collecting rainwater, growing in small spaces and vermi-composting.

The Youth on Land chapter is about including young people in farming, Working outdoors provides physical, emotional and spiritual well-being; reduces stress, social anxiety, depression, disease and impulsivity and increases focus, creativity, agility, eye sight, life satisfaction and more. It provides a sense of a life worth living. For three years, Soul Fire Farm had a Project Justice which trained court-adjudicated youth at their farm for 50 hours, instead of them being persuaded by the lawyer to accept a plea bargain for a lighter sentence than they would get if found guilty (whether they were guilty or not). Once young people have a criminal record, they are more likely to become a target of law enforcement, and the pipeline from school to prison becomes cemented in place.

Book Review: Start Your Farm, by Forrest Pritchard and Ellen Polishuk

Start Your Farm: The Authoritative Guide to Becoming a Sustainable 21st Century Farmer.  Essentials for Growing and Raising Vegetables, Fruits, Livestock, Grains for Market. Forrest Pritchard and Ellen Polishuk, The Experiment, New York. ISBN 978-1-61519-489-6

This is a book for new farmers, from two Virginia farmers. It is not an instruction manual on growing crops or raising livestock, nor on accounting and marketing. It is a book of suggestions on what aspiring sustainable farmers need to ponder, reflect on, take a cold hard look at before starting a farm of their own. It is a hybrid of insights, self-help wisdom, business savvy, and experience at the pointy end. The book addresses the huge problem of finding affordable land, and coming up with retirement plans that let you pass the farm down to the next generation, rather than selling it so you have a retirement fund. Their goal is to inspire as many new farmers as possible, so the focus is on small-scale manageable operations, which can provide success, and a very satisfying, joyful experience, along with the long hours of hard work.

The last chapter of the book, “Go!” can stand alone as a wonderful encouragement to new or beginning farmers – or actually old and retiring farmers too! The chapter is beautifully poetic. It leads us step by step through Your First Day, Your First Harvest, Your First Sale, imagining what that will be like. Next follows the caution: “It’s not rainbows and sweet breezes all the time.” Here’s encouragement to be prepared, to do what you have to, to respect the forces of nature, and be ready for the amazement, the unexpected awe and respect for nature. “The only thing we know for sure is that when we pour our passion into what we love, we end up with more than we give.”

Forrest Pritchard

Forrest is a seventh-generation farmer, raised on a 2000 acre farm that has provided corn, soybeans, apples, cherries, cattle, pigs, chickens. When his turn at the helm came, he transitioned the farm to sustainable livestock. Ellen is a first-generation farmer, growing vegetables since she was a teenager. She was hired in the 1990’s to manage one arm of Potomac Vegetable Farms, and went on to own this much admired and successful operation. This book provides different sorts of wisdom from each author. Hence each writes the chapters they have most expertise in, with some cross-fertilization of ideas. Both are very engaging writers.

Ellen Polishuk

As recently as 100 years ago, almost 40% of Americans were full-time farmers. Today it is less than 2%. The responsibility for feeding our society rests on the independent, altruistic farmers who devote their efforts to produce food for everyone else. Forrest calls them volunteers.

The authors caution that farming is for pragmatists, not perfectionists. Getting something 100% right in farming is not only rarely possible, it’s also rarely necessary. It’s better to be able to hoe beans quickly, with a few casualties, than to spend forever hoeing perfectly. There’s just too much to get done in a timely way. Good enough is better than perfect. Time is as valuable as money. In the short-term, you may be able to use off-farm income to help you get your farm up and running. Long-term (or sooner!) you’ll need to make enough for the farm to pay for all work done, and also make a profit (for retirement, kids’ college fund, a new tractor, another hoophouse).

Each chapter ends with a few searching questions, to help you get the most out of what you just read. Questions to help you assess your strengths and weaknesses, explore things you were ignoring and generally prepare yourself for the exciting huge task ahead. They also caution against biting off more than you can chew initially. Don’t grow every vegetable and flower and raise every possible kind of livestock! Start simpler and build up to your ideal level of diversity.

Don’t assume you should start by buying land. Life will be easier if you find land to farm that you don’t have to buy. The key is access to land, not acquisition, and the authors provide many models of how this can come about. There is a whole generation of farmers who want to retire, help a new generation of farmers start farming and see their land continue in agriculture. Debt-financed land purchasing is their least-recommended route. If that’s what you have to do, bypass conventional banks, go to the Farm Services Agency, which offers farm-friendly financing options, or look around for companies specializing in loans to farmers.

Forrest explains the blind-spot many of us have about compensating for the value of the land. The land, as an investment, needs to provide a financial return, in the same way that you’d expect from a pile of cash equal in value to the land. You wouldn’t leave the pile of cash under the mattress – you’d invest it so it would grow in value at least as much as annual inflation. And yet it can be hard to see that if we don’t get a similar return from a piece of land, it becomes an asset that steadily loses value that we are subsidizing with our time.

Forrest explains how the nation came to expect cheap food, and the consequences this has for farmers, and farming land. He explains how, from the sixteenth century onwards, land in North America was given free (we know who they took it from) to those favored by the people in power; to soldiers returning from the Revolutionary War; to those willing to farm in Florida (by Spain), or California (by Mexico); and then under the 1862 Homestead Act 270 million acres were given to 1.6 million farmers, a practice that continued as late as 1986 in Alaska. This lead generation after generation to not account for the value of the land properly. And so, cheap lettuce, cheap hamburgers, and a big challenge for farmers today to make a living and buy land.

Ellen writes an important introduction to soil physical composition, chemistry, biology, and explains replacing nutrients removed in crops. When visiting potential farms, give the soil good attention. This topic comes up again when Forrest writes about the importance of “putting things back” whether that’s tools or soil nutrients.

Ideas of complete independence and creative freedom as farmers can be a figment of our imaginations. We get a clear explanation of the Chicago Mercantile Exchange and how this is going to have effects (which we have no control over) on our costs and our income. Your hard-striven-for crop might end up losing in the competition with an imported bumper crop being sold at rock-bottom prices. I’m also thinking about this year’s US soybean farmers whose markets in China have been strongly damaged by tariffs. For maximum independence from uncontrollable factors, look for sustainable markets that are less dependent on mainstream commodity system supplies or outlets. Identify a need, find the angle that is the best fit between your local customer and your strengths, foster your relationships.

Ellen’s chapter on Tai Chi Economics suggests methods to deal with uncontrollable outside economic forces, such as regional competition, government policies, national drought, international competition. What we can charge for tomatoes in Oregon is impacted by the price of natural gas in Pennsylvania, or the wages of underpaid farm workers in Florida. In Tai Chi, use grace to meet incoming force, engage that force until it wears itself out, and learn from your opponent. “The soft and the pliable will defeat the hard and the strong” (Lao-tzu). Develop holistic skills to make a profit while growing nutritious food for the world. “Those who say it can’t be done should not interrupt those who are doing it.”

“Profit” is not a dirty word – profit allows the farm to grow and develop, pay decent wages, and provide security in case of disaster, and generally fund your life. The Tai Chi opportunity: make a profit while achieving the triple bottom line of a sustainable business: ecological stewardship, social justice, and economic viability.

Veggie Compass is a free farm management tool for diversified fresh market vegetable growers. It uses a spreadsheet to help farmers compute the real costs of growing a hundred crops and several different marketing channels. This tool can help farmers find which crops are their most successful, and which are the losers. The choices become clearer. If you are selling eggs at $6 a dozen, but they cost you $7 to produce, you’d do better just handing out dollar bills and not keep the hens at all. Let the antiquated notion of cheap food flow right past you! No other business apologizes for supplying a high quality product at a fair price. Record-keeping (noticing and writing down what happens and how well it worked) enables you to make improvements, rather than random changes.

Forrest introduces the Money Triangle. Financial stability depends on your potential to earn money, save money, and give money, in a balanced way. Savings are the catalyst for financial success. He suggests the 10% Plan. Make at least 10% net profit, save at least 10% of the profits (invested at 10% interest), give away 10% of what your investments make for you. It’s also a good rule for debt: never borrow more than 10% of your gross annual income, or pay more than 10% interest, preferably not more than 5%.

Three rules for beating the odds in farming: 1. If it’s broken, stop and fix it (relationships as well as tools); 2. Put it back where you found it (soil nutrients as well as tools); 3. Do what you say you are going to do (your customers’ trust, as well as faith in yourself.)

Forrest points out the wisdom of accepting that you won’t be able to function as a superior producer, an excellent bookkeeper and an all-star salesperson for more than a couple of years – you will need to get some help. Perhaps temporarily hire a professional salesperson who seems a good match, to identify good sales channels for you.

Ellen writes on Love, Work and Harmony. Grumpiness should be reserved for the time working alone! Build up relationship skills, you’ll need them with workers, friends and customers. To earn an annual income of $40,000 to $50,000, you would need to grow, harvest and market $125,000 worth of agricultural products. This is very difficult for one human alone. You need a workforce, and for that, you need good communication. Interns are students, not unpaid workers. The farmer has an obligation to educate, coach, encourage, and train any interns. This takes time away from production. Communication dramas can be the hardest part of farming. Learn early on how to speak your truth without criticism or blame and learn how to listen without taking offense. Keep time for the important people in your life, learn to leave the stresses outside your house, stick to daily finishing times. And don’t expect too much of yourself. “If you think you can farm and parent small children at the exact same time, you are doing neither activity well.” (Jean-Martin Fortier). If you have more than six people working for you, then keeping them, happy and productive is a full-time management job (Chris Blanchard). Don’t expect to cope with farming on your own in a place where you don’t know anybody – make a priority of finding folks to connect with.

Forrest writes on the Beautiful Paradox of Failure. No two seasons are the same. “Sustainable farming is built around the expectation that things change, that adaptability and innovation remain paramount, and that failure, when it occurs, is a critical teaching tool.” Failure arrives in many forms, despite all efforts to prevent it. And yet, without failure, we are less likely to improve. Forrest also discusses failures of faith, periods of despondency (mostly during droughts). He invites us, in the end-of-chapter questions, to think back to our biggest failures, how they shaped us, what we learned, and whether it still feels like a failure, in hindsight. Mine was the year I left the sweet potatoes in the ground too late, hoping for more growth to make up for a late start. Fall turned wet and cold and the sweet potatoes rotted or got chilling injury. It was a big mess. I learned a lot more about sweet potatoes as a result. It does still feel like a failure, although one of understandable ignorance. No-one around me knew any better at that time. I think it lead to me doing more research and record-keeping, perhaps even helped shape my path as a writer.

Ellen writes about how to appreciate the beauty around us, the daily moments of wonder, and our healthy lifestyle, although perhaps not the midnight struggles in the rain to set some emergency to rights. We do learn that it doesn’t matter if we have a headache, or feel lazy or sad, somethings just have to be done. Ellen calls this the priority of biology over attitude. We can call upon the grounding resources of clean air, vibrant plants, as remedies for our off days. We know producing food is a good and noble cause. If you read the final chapter first, read it again now!

Book Review: The Lean Farm Guide to Growing Vegetables: More In-Depth Lean Techniques for Efficient Organic Production, Ben Hartman

Book Review: The Lean Farm Guide to Growing Vegetables: More In-Depth Lean Techniques for Efficient Organic Production, Ben Hartman, Chelsea Green, $29.95, publication November 2017

When I read Ben Hartman’s first book, The Lean Farm, and wrote my review in October 2015, I was on the path from curious and enthusiastic skeptic to enthusiastic-fan-with-reservations. I rejoiced in the ideas of reducing wasted effort, being more efficient, more successful at producing food, happier, less stressed. Ben Hartman, Jean-Martin Fortier and Curtis Stone are three successful commercial vegetable growers who clarified for me that a small-scale farm could be more efficient, more sustainable and certainly more pleasant if worked mostly with manual tools and a walk-behind tractor (rototiller) than with a ride-on cultivating tractor, which was the direction I had been looking in. We really didn’t want to be spending our time on a tractor, or under it, maintaining it. We didn’t want a class of tractor-driving gardeners divided from a class of hands-in-the-soil gardeners. Nor did we want to re-format our gardens and give up all the space to allow a tractor to turn around.

When I heard about Ben’s new book, which he describes as “a how-to manual, with a lean twist,” I sought it out. Here are the many helpful details to improve how we do our vegetable growing. His introduction reviews the five core Lean Principles, so if you haven’t read his first book first, you can still understand the thinking behind his systems. With Ben’s first book, I expected push-back from crew members who would judge his ideas and techniques as inflexible, too detailed, nit-picky. Was this just my projection? I found it very thought-provoking, and I was constantly assessing our farm as I read it. I had a rough triage of inner comments: “ah, we already do that (well)” “oh we really need to do that” “ooo I’m not happy with that idea.”

By and large I valued the actual techniques and strategies. I bristled against his classifying planning, organizing and other managerial tasks, as well as bed prep, hoeing, weeding, thinning seedlings as type 1waste (muda, in Japanese). That just didn’t sit right with me. Perhaps it’s a word that doesn’t translate well. A commenter on my blog clarified this for me. She likened type 1 waste to Stephen Covey’s Quadrant 2 (Important but Not Urgent) in the Seven Habits of Highly Effective People. Quadrant 2 includes maintenance, advance planning, being prepared. Preventing problems, or dealing with them to minimize their impact is important. I could never call it wasteful. In fact, I see attention to Quadrant 2 as a sign of good leadership, good farming. We need to make time for the important tasks that are not yet urgent. Scout for pests, don’t ignore them till they overwhelm your crops.

In this second book there is acknowledgement that while muda is usually translated as waste, not all muda should be completely eliminated. Simply minimize the time and energy given to non-value-adding activities. OK, I can go with that. In fact, the list of 10 forms of muda doesn’t say a word about managerial activities. Or about reading books, or writing reviews!

Ben takes a Lean look at crop planning, bed prep, compost-making, seed starting, transplanting, the Japanese paper pot transplanter, direct seeding, weed and pest control, sales, seven crop case studies, greenhouses, and finding good land and building a farm. There are valuable appendices with recommendations on tools, crop varieties, dollar-value-per-bed, a photo gallery of seven more crops, a Japanese glossary, and a book list.

I’m a fan of careful crop planning, and I acknowledge that doing it efficiently is important. There is definitely such a thing as “over-planning.” I think experience teaches us what we need planned and what we don’t. When the same people grow the same crops on the same farm year after year, lots can be taken as decided. When we have built fertile soil and there are no new plagues, we can get away with minimal crop rotation. At Clay Bottom Farm (in Indiana), Ben, Rachel and their crew are earning their living from less than one acre, growing and selling specialty produce to restaurants, farmers markets, and through their CSA. They grow a lot of salad greens and tomatoes, along with some root crops, peppers and eggplants, zucchini and cucumbers. Sweet corn, beans, peas, winter storage crops don’t feature much or at all. They have found the crop mix that works for their customers (that is one of the 5 Lean Principles). The situation in our gardens seems more complicated, but the point remains: streamline the planning, don’t over-work it.

The concept of load-levelling (heijunka) is valuable – look at the plan for the year and keep it manageable every month. And plan in a vacation for everyone. We try to stagger our vacations so that there are always a few people who can run things, taking turns. We tried reducing the August workload, moving one big task to September, and taking a few weeks off from lettuce production. Ending our watermelon harvests at the end of August and our winter squash at the end of September were helpful in keeping fall work manageable. We’ve got better at “doing-in” plantings of beans, cucumbers and summer squash if they are getting to be oppressive.

I was particularly excited to see instructions to build a seed germination cabinet à la Hartman. Like Ben, we use discarded refrigerators. Ours rely on incandescent light bulbs, which are a dwindling “resource”. Some would say “good riddance” but we are actually using the heat the bulbs generate, as well as the light. Ben’s clever design uses a pan of water heated by an electric element, on a thermostat. This could be our next germinator!

I’ve read about the Japanese paper pot transplanter before, and concluded it’s best for plants set out at 6″ spacing or less, and fairly large plantings of one thing. I’m intrigued – would love to try it, even though we do more direct sowing of close-planted crops than Ben does. I love the idea of a carefully-designed manual machine for transplanting, especially as my knees get older, and like squatting less. This chapter is worth the price of the book to anyone about to buy the transplanter. So many tips, including Ben’s Paper Pot Cheat Sheet. The direct-seeding chapter explains the Jang JP-1 seeder, and the same message applies about buying the book if you’re buying the seeder.

Weeds and pest control without muda – Yes, of course, focus on prevention, rather than managing. Ben gives 5 Steps to No Weeds. Yes, time saved there would pay for the price of the book too! Pests, Leaned Up is about Biological IPM: rowcovers, beneficial insects and biological sprays if needed.

The sales chapter looks at transportation logistics, sensible delivery vehicles. As Ben says, “Big vehicles, we learned, don’t by themselves lead to large sales”. Avoid over-production. Set up your market booth for smooth flow.

The case studies explore how Clay Bottom farmers decide which varieties to grow, where and when, and of course, how much. The case study crops are tomatoes, baby greens, kale, head lettuce and romaine, carrots, other bunched roots, and peppers. Here’s good information from someone who has paid exquisitely good attention to what works and what doesn’t.

The chapters on finding good land and setting up your farm in a well-organized, Lean, way will save new farmers some costly (livelihood-threatening) mistakes, and help the rest of us think twice about why we store our tools where we do, and so on. The greenhouse chapter is brief, and yet full of gems about design.

Holiday Season approaches, I’m just sayin’. Or invest in your farm, with this worthwhile business expense. In other words, buy this book!

Book Review, The Greenhouse and Hoophouse Grower’s Handbook, by Andrew Mefferd

The Greenhouse and Hoophouse Grower’s Handbook,  Organic Vegetable Production Using Protected Culture. by Andrew Mefferd. Chelsea Green.March 2017, $34.95. ISBN 978-1-60358-637-5

I was lucky enough to be asked to write an endorsement for this book, and was sent an uncorrected proof to read. Now I have the full color, published version, and I’m poring through it once again. Andrew Mefferd is the editor and publisher of Growing for Market magazine that I sometimes write for. Prior to that job, he worked at Johnny’s Selected Seeds, in the research department for seven years. Born in Virginia, he apprenticed on farms in six states on the west and east coasts, then farmed in Pennsylvania. He now farms in Maine, and has a good appreciation for the difference a different climate can make.

This is not an “Everything you always wanted to know to get started with a hoophouse” book, nor a compendium of greenhouse crops, pests and diseases. On the contrary, this book focusses down on the precise details of successful practices to grow what Andrew has determined to be the eight most profitable crops using protected culture: tomatoes, peppers, cucumbers, eggplant, lettuce, greens, microgreens and herbs.

This is a book to come back to each time we want to know more about one of his topics. If I were about to launch into microgreens, I would follow Andrew’s methods. I tend to read quite widely on vegetable growing topics and I’ve read some very fussy time-consuming microgreens-growing instructions for home gardeners. I haven’t seen another book be so down-to-earth with an efficient and professional growing method that uses only simple tools and supplies. Those wanting to grow microgreens in quantity, and make a living from it will find plenty of information to get started or to fine-tune their operation.

The part of the book I’m most excited about right now is the information on what plants need at different stages of growth, in terms of balance between temperature, humidity as it affects transpiration, daylength, light intensity, carbon dioxide, oxygen, water and nutrients; and how to use this information for “crop steering” – adjusting conditions to select for leaf growth or fruit development. Here are the details to get it right. I once got a light meter to compare the light transmission through clouded old glass and new glass (I wanted to know if it was worthwhile to replace the glass in our greenhouse). But then I didn’t know how to use the information. Now I know that 1% less light will lead to about a 1% lower yield. Specific information like this can be hard to dig up bit by bit on the web. Here the gold nuggets have been screened for us, and the mud left behind.

The book starts off with a sixty page section on the basics of protected culture: the why, what and how of the various options of structures and utilities you might be choosing among, with a chapter on economics and efficiencies. The main part of the book then dives into the specific practices that help the eight crops do best. Chapters on propagation, pruning and trellising; temperature control and crop steering; and grafting are applicable to many of the recommended crops. Next follow chapters on each of the crop groups, and appendices on hydroponics, pests and disease and tools and supplies.

Andrew is obviously a very attentive farmer, and one who keeps good records. And here we can all benefit, whether experienced growers looking to improve our game, or beginners wanting to grasp success from day one. Serious backyard gardeners could use this book too, not only commercial growers. Facts are facts, results are results. Not everyone will want to follow all of the recommendations immediately or perhaps ever. In our hoophouse in Virginia, we grow two beds of early tomatoes in our hoophouse with just enough trellising to keep them upright, and minimal pruning. As soon as our outdoor tomatoes are producing well, we pull out the hooophouse rows. Our climate doesn’t warrant keeping them in the hoophouse, and in fact, it may get too hot in there for them. Our climate is full of fungal diseases, so crop rotation is very important to us, and the sooner we don’t need tomatoes in the hoophouse, the sooner we can remove them and their fungal spores!

But I do remember growing tomatoes in a glass greenhouse in northern England, and how we cherished those plants! I had started to experiment with side-grafting 25 years ago, in hopes of having sturdier tomatoes. We pruned and twined, and every ripe tomato was precious to us. It was late September when I moved to Virginia, and I helped the garden crew harvest Roma paste tomatoes, which were grown sprawled on the ground. That in itself was a shock – gosh these people don’t hold their tomatoes in very high regard, they let them rot on the ground! The crew member working next to me shocked me further: “Stomp on the green ones” she muttered under her breath. Apparently so great had been the harvest of these paste tomatoes that the crew was exhausted from harvesting and wanted to be done!

So, select the sections of Andrew’s book that speak to your needs and your climate. There’s something for everyone. You don’t need to abide by it all to want the book. It will easily pay for itself if you find only one new practice to adopt this season. But read the whole book anyway, and you can develop a fuller understanding of the big picture, a new management strategy and a set of skills to deal with the challenges that arrive unbidden. Andrew has tested all these practices as a small-scale grower himself, and he does this because he’s a passionate supporter of local food, sustainably grown, and sees protected cropping as a way to increase local food production by increasing on-the-ground crop insurance in the face of the unpredictable.
