More about Jamaica’s Source Farm Project

At last I got the photos from my Jamaica trip from my camera to the computer. I didn’t take many photos – as I said in my other Jamaica post, it rained most of the time. As you see in the photo above, bananas grow well, the land at Source Farm is hilly, the office is a repurposed and repainted shipping container

At the beginning of June the BBC visited Source Farm and made a podcast as part of the On Your Farm series, and called it Jamaica’s Organic Revolution.

You can listen to all 22 minutes of it for free, and hear the people I stayed with at Source Farm as well as Mr Brown, one of the farmers I met with. I can only link to the program, not embed it, so click the link below

I thoroughly enjoyed listening to the voices of my new friends, and being reminded of the farm and the countryside.

Viewing my photos reminded me also of the “domestic wildlife.” First the friendly ones:

Then the creepy crawlies, the two inch millipedes that were everywhere. You have to be careful not to crush them, because the liquid inside them can cause burns. I never had that problem, and scooped them up by the handful to throw outside each night, only to find them back inside by morning. I concluded that each house had its allotment of millipedes and it was best to ignore them!

Things I noticed and learned from the farmers about growing crops in the tropics have led me to think more about how plants respond to temperature and day-length, and I want to learn more about this when I have time. As I said in my Asian Greens for June post:

“Last month I was in Jamaica and saw how they can grow kale in very hot weather. “

I had a comment from a reader about successfully growing Joy Choi in hot summers as well as Tokyo bekana. It’s revelation to me that at least some brassicas can grow in hot weather as long as the temperature never drops below 50°F (10°C), which triggers bolting.

Swiss chard I take for granted as a summer leafy green – it’s a biennial and usually won’t bolt until the second year. The Ruby chard seems the most prone to bolting. We’ve given up that one in favor of Bright Lights, as well as Fordhook Giant green chard. Chard is popular in Jamaica too.

A green which is not common here in the US, but is very popular in Jamaica is callaloo, which is a type of amaranth. I enjoyed eating it at Source Farm. I tried growing it in Virginia one year, when I was researching summer cooking greens in spring 2015 for an article in Growing for Market. Here’s what I said then (when I maybe misspelled callaloo):

Vegetable amaranth,  Amaranthus species.

In spring use the young leaves for salad. Larger leaves make tender and nutritious cooked greens. Calaloo is an amaranth (but sometimes other crops have this name), used to make a green Caribbean stew. Joseph’s Coat, Amaranthus tricolor, is an eye-catching plant with red, green, and yellow leaves that may also include patches of pink, bronze, purple and brown. This tropical plant thrives in really hot weather. It is a huge plant, 4-6’ tall. Carol Deppe in The Tao of Vegetable Gardening recommends All Red for a spectacularly colorful leaf, especially for salads, and Green Calaloo and Burgundy for fast-growing greens. She reports they all taste the same to her raw, and all taste the same when cooked. So choose by preferred color and rate of growth.

Seeds should be started indoors in spring, and transplanted once all chance of frost has passed, when it is time to plant corn. Alternatively, broadcast with aim of getting plants 4” apart. Each time the plants reach 12” tall, harvest the top 8”. Pinch back often to push out new leaves and prevent reseeding (it can become a weed problem). If your farm has lots of amaranth weeds, you won’t want to risk adding another. Also, if weed amaranths are eaten by the striped fleabeetles, your cultivated amaranths will also suffer. (Those are the two reasons we gave up on them.)

William Woys Weaver (Saladings, Warm Weather, Mother Earth News) is a fan of ‘Bliton’ or ‘Horsetooth Amaranth’, Amaranthus lividus (Amaranthus viridis). He reports that it is the easiest and most prolific of summer greens. Seed should be started indoors, except in the South. Transplant seedlings when it’s warm enough to plant beans (Frequent advice for many of these hot weather greens). Alternatively, broadcast where it is to grow after all danger of frost is past. Thin the seedlings for salads or harvest plants about 12” tall and cook like spinach. When the plant is older, the stems get too tough, and then only the leaves and new shoots should be used. In parts of the South, it has become a weed – “Grow responsibly,” as Barbara Pleasant says in her Mother Earth News blogpost Warm Weather Spinach Alternatives.

Starting with what’s being harvested now – squash and zucchini are coming in nicely. The hoophouse Gentry yellow squash (chosen for being fast-maturing) is coming in by the bucketload, and the outdoor yellow squash and zucchini have started producing.


I’m off to Burlington, Vermont this weekend, for the Mother Earth News Fair. I’m giving two workshops:

Cold-hardy Winter Vegetables,on Saturday 6/10 at 11 am on the Yanmar Sustainability Stage, immediately followed by book-signing at the Mother Earth News Bookstore noon- 12.30.

Producing Asian Greens on Sunday  6/11 at 3.30 pm on the Heirloom Gardener Stage.

I’m also doing demonstrations of tomato string-weaving at the New Society Publishers booth 2611, near the Mother Earth News Stage (not the Bookstore this time), at 10 – 10.30 am and 3-3.30 pm on Saturday and 10 -10.30 am, 11- 11.30 am and 2- 2.30 pm on Sunday. Check out my Events page to see the pink sparkly tinsel tomato plant models I use!


At the Heritage Harvest Festival near Charlottesville, Virginia, on Friday September 8 (the Premium Workshops before the main Festival), I’m presenting on Growing Sweet Potatoes at 3.30-4.30 in classroom 7, followed by book-signing at the Monticello Bookshop.


The June/July summer issue of Growing for Market magazine is out, and includes my article on Hoophouse soil salt buildup. This is an issue we have been dealing with – we see white deposits on the soil. I did a lot of research and found ways to water the salts back down deep in the soil profile. I also gathered information on how to measure and monitor salinity, and how to understand the test results and their different testing methods and different units of measure. I learned about salt tolerance of different crops, the plant symptoms of excess salinity, and how to prevent the problem in future. This topic is rising in importance as more people use hoophouses with drip irrigation systems. We were blithely ignorant for our first several years of hoophopuse use, as salinity takes a few years to really develop, and there wasn’t much information available.

I’m also looking forward to reading the other articles, especially Summer lettuce lessons from Southern growers by Jesse Frost. There are some great photos of beds covered with hoops and shade-cloth, which show a good system. I always appreciate articles written for southern growers, which can be in short supply.

Daisy Fair in Utah’s zone 5 has written about moveable tunnels with in-ground hydronic heat. So there’s information for cold climates too. Sam Hitchcock Tilton has an article with tips learned from Dutch and Swiss farmers. Robert Hadad advises on careful monitoring of costs of production in order to actually make a living from farming. The flower growing article in this issue is from Debra Prinzing and is about American Flowers Week, a chance to highlight American-grown flowers with some light-hearted fun photos.


The May/June Organic Broadcaster just arrived in its paper format – I’ve had the digital one for a while. Good thing I’ve got that long car ride to Vermont this weekend to catch up on my farming reading!

The front page story this time is about Kansas farmers, Tim and Michael Raile, transitioning thousands of dryland (non-irrigated) acres to Organic steadily over the next 5 or 6 years. Dryland farming focuses on moisture retention. The Railes grow a wheat/corn/
sunflower/milo (grain sorghum)/fallow rotation. They are also trialing some ancient grains.

Organic production in the US is not meeting demand, and organic imports are increasing, including organic soy and feed corn, not just bananas and coffee. More farmers want to produce Organic poultry, eggs, milk and meat. And so they are looking for Organic feed at an affordable price. This is often imported, which raises issues about how Organic Standards vary from one country to another, and the bigger issue of sustainability – not always the same as Organic! Does it really make sense to ship in grains to feed livestock?

Harriet Behar writes about the true meaning of Organic and overall methods of production. It’s not just about following rules on allowed inputs and materials – it’s a whole approach to how we treat the soil, our plants and livestock.

Hannah Philips and Brad Heins share research on how cover crop choices can influence the fatty acids and meat of dairy steers. Jody Padgham writes about CSAs responding to competition and decreasing membership by offering more options on shares and delivery. Gone are the days of “One box, one day, one price” CSAs. Numerous modifications of the basic CSA model have sprung up to better fit the diverse needs of customers (members). Kristen McPhee writes about the Vermont Herb Growers  Cooperative, which buys from various small-scale growers and aggregates orders to larger buyers. Other topics covered include lessons learned from Hawaii’s GMO controversy, paying for end-of-life care without losing your farm, and many short items and classified ads. As always, a newspaper packed with information.


And by the way, we’re also picking blueberries – ah! heaven!

Garlic scapes, upcoming events, hoophouse seed crops

Garlic Scapes
Photo courtesy of Small Farm Central

I always know when garlic growers in slightly warmer or more southern climates are starting to find scapes (the edible firm flower stems of hardneck garlic) because my posts about scapes suddenly become popular! My posts “Garlic scapes! Three weeks to bulb harvest,”  and “Garlic scapes to cheer us up” have been reread a lot recently, and Harvesting garlic is due for attention any time now. My Growing Great Garlic slideshow is here. Click the diagonal arrows to view it full screen.

And sure enough, our own scapes are ready too, even though this is a week earlier than usual.We harvest two or three times a week until there are no more. I love garlic scapes as one of the first outdoor crops of the spring, and a flavor different from leafy greens and stored roots, the staples of early spring.

Our tulip poplars are flowering now too, also early. Our average date for those is 5/1, and we’re a few days ahead of that. When I was a beekeeper it was important to be ready for the tulip poplar flowers, because that was our big nectar flow of the year, and I had to dash out to the beeyard and stack up 5 supers on each hive. I had to give up on the beekeeping because the combination of lifting heavy boxes and twisting was hurting my back too much. Oh, and those heavy boxes were full of thousands of stinging insects, but I didn’t mind that bit as much. The flowering of tulip poplars and the germination of ragweed are both phenology signs that signify that the Growing Degree Days have reached 200 (on a base of 50F) and that conditions are warm enough to sow sweet corn. Myself, I watch the young leaves on the white oaks and when they are the size of a squirrel’s ear, I decide it’s warm enough for corn.


This weekend I will be at the Mother Earth News Fair in Asheville, NC. Click the link to see the location, the workshop schedule and the list of vendors who’ll be there. I’m presenting two workshops, Growing Sweet Potatoes from Start to Finish on Saturday 5/6 at 12.30on the Yanmar Sustainable Agriculture Stage, followed by book-signing and chatting at the Mother Earth News Bookstore; and Succession Planting for Continuous Vegetable Harvests on Sunday 5/7 at the Heirloom Gardener Stage.

Of course, you’ll need to be there and  hear me speak to get the most out of it. I’m also doing short demonstrations of How to String Weave Tomatoes at booth 2800, New Society Publishers (near the Bookstore) on Saturday at 10 am, 11 am and 5 pm, and on Sunday at 10 am and 11 am. They’re half-hour time slots. My table top demo kit uses #2 pencils and pink tinsel.

The May issue of Growing for Market magazine is out, including my article about growing seed crops in hoophouses. I interviewed Clif Slade, founder of the 43560 Project at Virginia State University, about several creative sequences of food crops and seed crops he has grown in a high tunnel. (Collards, okra) as well as plant starts (sweet potatoes, onions). He farms in Surry County, Virginia.

Also in this GfM, Simon Huntley of Small Farm Central encourages small farmers to set aside two hours a week for a quick and efficient bit of online marketing “One Photo,
One Paragraph”. His goal is to help farmers stay in the spotlight with their products, without having to spend a great deal of time on it in the busy season.

Conor Crickmore has an article about preparing and laying out no-till permanent raised beds very precisely in a hoophouse. He uses the Quick Cut Greens Harvester to mow off over-size baby salad crops to clear the bed prior to broadforking and adding needed soil amendments.

Spencer Nietmann writes about what it really costs to start a farm. Jesse Frost discusses various types of plastic to cover hoophouses  (high tunnels), and lastly, Jane Tanner writes about native perennials for flower farms

Hoophouse slideshow, Ruminant podcast, potatoes planted

Here’s my updated Spring and Summer Hoophouse slideshow, that I promised all the people at my Organic Growers School workshops. I rearranged the slides in what I think is a better order and revised the resources section.


The Farmers Aren’t All Right.
Podcast from the Ruminant

I also took part in an interview with Jordan Marr for a podcast with The Ruminant: Audio Candy for Farmers, Gardeners and Food Lovers. It’s about farmers’ struggles with mental health problems, trying to cope with the many and varied stresses, while the public wants farmers to appear competent and blissful with all that time in the Inspiring and Nurturing Outdoors.

“Farming is tough work. The unpredictability of the job and the pressure to present a curated, bucolic version of the work can easily lead to various kinds of mental health problems: despair, feeling overwhelmed or like a failure, or even depression. In this episode, co-produced with Jessica Gale of Sweet Gale Gardens, we discuss the prevalence of mental health problems among farmers, and how to address them.” Jordan Marr

As well as Jessica Gale, the episode includes discussion of Professor Andria Jones-Bitton’s work and interviews with Jean-Martin Fortier of The Market Gardener and Curtis Stone of The Urban Farmer.


The March issue of Growing for Market is out. Nothing from me this month (I have articles for May and June/July coming up). In this issue. There are articles about No-till vegetable farming (Conor Crickmore at Neversink Farm, in the Catskill Mountains of New York), and Bio-integrated farm design by Shawn Jadrnicek, co-author with Stephanie Jadrnicek, of The Bio-Integrated Farm: A Revolutionary Permaculture-Based System Using Greenhouses, Ponds, Compost Piles, Aquaponics, Chickens and More. Lots of water in this book, and very practical. There’s an article on A DIY mobile cooler for moving and storing perishable foods  – an insulated trailer using Cool-Bot technology by Cary Rivard, Kansas State Research & Extension Horticulture & Forestry & Extension Vegetable & Fruit Crop Specialist. Karin Tifft has written The “other” reasons to grow in a greenhouse: climate, light, good use of space, reduced wastage of produce, energy conservation and more. Andrew Mefferd, the editor has written on growing cucumbers umbrella style under cover. Finally, Debra Prinzing writes on Making your mark with local branding.

Lettuce in February, Growing for Market, open seed flats

Baby lettuce mix in our winter hoophouse.

We still have plenty of lettuce to eat, although our first sowing of baby lettuce mix in the hoophouse has come to its bitter end, and the second sowing isn’t quite ready (I think we sowed it a bit later than intended). We are still harvesting leaves from the large lettuce we transplanted in October.  Soon we’ll have the second and third baby lettuce mix sowings to bring a welcome change. We are about ready to transplant our first outdoor lettuce, to feed us mid-late April.

Here is a month-by-month planting and harvesting narrative for our hoophouse lettuce in Zone 7, from September to April:

September: Sow cold-hardy varieties in the second and third weeks (outdoors or in your greenhouse) to transplant into the hoophouse at 4 weeks old .

October: 4 weeks after sowing, transplant those lettuces at 8” spacing to harvest leaves from mid-November to early March, rather than heads. In late October, sow the first baby lettuce mix, for up to 8 cuts from early December to late February, and sow a small patch of “filler lettuces” to replace casualties in the main plantings up until the end of December.

November: 11/9 sow more filler lettuce, to be planted out in the hoophouse during January. Transplant the first “filler lettuce” to replace casualties. Harvest leaves from the transplanted lettuce.

December: Use the “filler lettuce #1” to replace casualties or fill other hoophouse space, for lettuce leaves in January and February, or heads in February. At the end of December, make a second sowing of baby lettuce mix, to harvest from late February to the end of March. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix.

January: Use the “filler lettuce #2” to fill gaps in the lettuce beds up until January 25. After that is too late here for hoophouse lettuce planting, and we use spinach to fill all the gaps, regardless of the surrounding crop. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix whenever it reaches the right size.

February: 2/1 sow the third baby lettuce mix, to provide up to three cuts, from mid-March to late April. In mid-February, consider a fourth sowing of baby lettuce mix, if outdoor conditions look likely to delay outdoor harvests. Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix when it sizes up. Harvest the first baby lettuce mix, clearing it at the end of February before it gets bitter.

March: Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix whenever it reaches size. Cut the third baby lettuce mix when it sizes up.

April: In the first half of the month, harvest the last of the transplanted lettuce as heads . Continue to cut the third baby lettuce mix until it gets bitter. Cut the fourth baby lettuce mix when it sizes up. Outdoor lettuce heads are usually ready for harvest mid-April. Plan to have enough hoophouse harvests until the outdoor harvests can take over.

The February issue of Growing for Market is out, including my article How to decide which crops to grow which I previewed some of here last August. I also included some of the material in my slideshow Diversify Your Vegetable Crops. Click the link to see the slideshow. This past winter we used this kind of process to reduce the amount of garden work for 2017. I’m retiring from garden management and the new managers  want to stay sane and not be exhausted all the time. We have fewer workers this year (the past few years actually), so we needed to slim down the garden and not go crazy trying to do everything we’ve done in the past. I’ll still be working in the hoophouse, the greenhouse, and doing some outdoor work, as well as being available to answer questions and provide some training when asked.

Back to Growing for Market. There’s a great article for new small-scale growers, from Katherine Cresswell in northern Idaho, Year One Decision Making, about starting a farm with only one implement. Careful planning lead Katherine and her partner Spencer to focus on fall, winter and spring vegetables, as no-one else around them provided these, and they had experience of winter growing from working on other farms. Clearly a high tunnel (hoophouse) needed to be in the plan. It was essential that they hit the ground running and have saleable produce within six months. The expense budget was very tight. They bought a BCS 739 walk-behind tractor (which they both had experience of) and a rotary plow. A very down-to-earth article to encourage any new grower with limited means.

There are reviews of three new books by GfM writers: Compact Farms by Josh Volk, Floret Farm’s Cut Flower Garden and The Greenhouse and Hoophouse Growers Handbook by Andrew Mefferd, the editor of GfM. Brett Grohsgal has written a valuable article about his 15 years experience with on-farm breeding of winter-hardy vegetables, both in the field and under protection of hoophouses. Informative and inspiring. Erin Benzakein has written about rudbeckias, the unsung heroes of summer bouquets, and Gretel Adams has written on new flower varieties to try in 2017.


I have a new post on the Mother Earth News Organic Gardening blog, Using Open Flats (Seed Trays) to Grow Sturdy Seedlings Easily – How to make reusable wood flats (seed trays) for seedlings, and use them to grow sturdy vegetable starts to transplant into your garden. This is a way to avoid contributing to the problem of agricultural plastic trash and be self-reliant in gardening equipment. You can also grow stronger plants by giving them a larger compost volume than plug flats or cell packs provide.

I heard that my MEN blogpost Green Potato Myths and 10 Steps to Safe Potato Eating was very popular in January, coming sixth in their table of most-viewed posts on all topics. This has been out there in the blog-iverse for almost 18 months, so clearly there is a lot of concern about eating healthy food and not wasting what we’ve grown.

The false spring has been barreling along. Last week I reported that we’ve seen a flowering crocus (2/17). Since then, we’ve seen daffodils and dandelions flowering, heard spring peppers and already the maple is flowering (2/25). These are all markers on our phenology list. The maple flowers on average 3/12, with a range (before this year) of 2/28 in 2012 to 4/2 in 2014. A 9-year record broken!

Last week I went to the annual conference of the Virginia Association for Biological Farming, held at Hot Springs Resort, Virginia. There were about 430 attendees, a big increase from last year. I gave two presentations, Spring and Summer Hoophouses, and Cover Crops. Here’s the Cover Crops slideshow.

The January 2017 issue of Growing for Market is out. It includes my article on Hoophouse style and design. As well as the Gothic/Quonset
decision and that on whether to choose  roll-up, drop-down or no sidewalls, this article discusses roads, utilities, irrigation, in-ground insulation, end-wall design, inflation, airflow fans, and bed layout to match your chosen method of cultivation.

Other articles include Barbara Damrosch on flower production on a small vegetable farm (beautiful photos!), Emily Oakley on planning to  grow only what you can sell (words of wisdom), Eric and Joanna Reuter with part two of their series online weather tools for farmers, Jed Beach on how to avoid and fix common financial mistakes we farmers make, and Jane Tanner on local food hubs. Plenty of good reading!

The first issue of Growing for Market that I ever picked up (years ago) had an article about flame-weeding carrots. I realized that that one article was going to save us more than the price of a subscription. Just one good idea, clearly explained, can save so much wasted time!

We won’t starve or get scurvy! Plenty of food in the winter hoophouse!

Climate change and pest control

p168i

I recently learned some more about online weather tools for farmers from Eric and Joanna Reuter in Growing for Market. The National Weather Center Climate Prediction Center (CPC) has a wealth of useful info. From the “WPC 7-day QPF” map above (Weather Prediction Center 7 day quantitative precipitation forecast) I see we could get up to an inch of rain over the coming week in central Virginia. Other maps on the site show we can expect above normal temperatures and rainfall for the first week of January. (I’m saying rain, because with above normal temperatures, the precipitation won’t be snow.)

There are maps with forecast conditions for the next month, the next three months and even the whole of 2018, although of course the more intervening time means more chance of things changing before we get there.There is a detailed discussion explaining “La Niña conditions are present, with a transition to ENSO-neutral favored during January-March 2017.” The report was written in November, predicting weak La Nina conditions continuing through March 2017.

Winter offers a good opportunity to explore these tools and get familiar with them (the abbreviations and technical language do take a bit of getting used to). If I were to open this site in mid-summer when already very busy, I think I would struggle to sit still long enough to absorb the information. By figuring it out at the slow time of year, I’ll be more ready to dip in and take advantage of timely info in the main growing season.

This week I also read an interesting article by Rebekah L Fraser in Growing magazine on the Push-Pull Method of pest control, which was developed in Kenya. In Kenya this method is used to protect crops from both invasive weeds and insect pests. Some plants can suppress others by selective allelopathy. Tick-trefoil not only suppresses some weeds but also repels pests, while conserving the soil in the process, and providing stock feed or green manure when cut. Plus, as a legume, the tick-trefoil fixes atmospheric nitrogen (which feeds the next crop) and reduces greenhouse gases (which helps save us all). This is the “push” half of the combination. Tick-trefoil interplanted with corn repels weeds and pests.

Push-pull pest control

Push-pull pest control

The “pull” half involves Napier grass as an attractive trap crop for corn borers. This trap crop is planted as a border around the corn patch. The female stem-borers are repelled by the tick-trefoil out of the corn to the border where they lay eggs on the Napier grass. It’s sticky exudates and sharp silica hairs kill the stem borer larvae when they hatch. Read more on www.push-pull.net .

It’s so heartening to read about organic sustainable ways farmers in sub-Saharan Africa are working to end hunger and poverty. And these principles can surely be applied to other crops in other regions.

Sweet potato slideshow, phenology article, Ira Wallace awarded

I’ve just got back from the Carolina Farm Stewardship Sustainable Agriculture Conference in Durham, NC. There were about 1200 people, five workshop slots, 12 tracks, lots of good, locally grown food, a whole pre-conference day of bus tours and intensive workshops, a courageous and inspiring keynote address from Clara Coleman on the joys and challenges of family and farm life. She and her two young sons are now living and working alongside Eliot Coleman (her dad) and Barbara Damrosch at Four Seasons Farm in Maine.

My sweet potato slideshow from my first workshop at CFSA is viewable above. Just click on the forward arrow. To see it full screen, click on the link below the image and then click the diagonal arrows when the new page opens. About 70 very engaged people attended that workshop. My other workshop was Sustainable Farming Practices for Vegetable Growers, which I’ll include next week.

I have also recently written a blog post for Mother Earth News Organic Gardening blog  called Saving Sweet Potato Roots for Growing Your Own Slips.

I enjoyed meeting old friends, making new friends, learning some good tips about different drip irrigation parts, how to sharpen and use a scythe, how many years half the henbit seeds are viable for (23 years!!), and picking up literature from the trade booths to digest later.

nov-dec-2016-gfm-cover-300The November/December issue of Growing for Market is out, including my article about phenology. Phenology is the study of recurring animal and plant life cycle changes in relation to the weather. Some changes are temperature-dependent, rather than (daylength-) calendar-dependent. The opening of some buds and the emergence of some
insects from the ground are related to the accumulated warmth of that season. Observations of certain changes can be used to help growers decide when to expect outbreaks of certain insect pests and when to plant certain crops. For instance, we look to the leaves of the white oaks to decide when it is warm enough to plant sweet corn. The oak leaves should be as big as squirrel’s ears. We have plenty of squirrels! Phenology is especially useful when the weather is extremely variable, which we can expect more of as climate change gets us further in its grip.

Also in this bumper edition of Growing for Market are articles on growing heading chicories (Josh Volk), milling your own logs on your farm (Mark Lieberth), online weather tools for farmers (Eric and Joanna Reuter), image-front-cover_coverbookpagea review of The Farmers Market Cookbook by Julia Shanks and Brett Grohsgal (Andrew Mefferd), and favorite perennials for flower growers (Jane Tanner). There are also two pages of cameos of books available from GfM. A seasonal tip about gift giving, I think.

I am working on a review of Soil Sisters by Lisa Kivirist, which I will tidy up and post soon.

Preparing for the Heritage Harvest Festival, winter hoophouse harvests

The Heritage Harvest Festival at Monticello, Virginia, September 9 and 10, 2016

Now, at the height of summer, I am looking ahead to speaking events this fall, winter and next spring. (I have been in the habit of turning down presentations from May-August, so i can focus on our gardens). My first booking is the fun and local Heritage Harvest Festival at Thomas Jefferson’s house, Monticello, near Charlottesville, Virginia. Click the link above to plan your visit.

Friday is devoted to classroom workshops and walking tours. I will be giving my presentation on Fall Vegetable Gardening on Friday 2-3 pm. It’s a ticketed event, limited to the 32 people who can fit in the classroom. After the workshop I will be signing copies of my book from 3.15-3.45 pm at the Shop at Monticello, and chatting to whoever comes by. There are  30 other workshops on Friday,  and 3 workshops on Sunday.

If your tomatoes don’t look as wonderful as those in the Monticello  photo above, you might be casting around for descriptions and photos of problems. Margaret Roach in her blog A Way to Garden, recently posted an interview with Dr Meg McGrath about tomato diseases, with photos. If you are worrying about Late Blight, you can sign up for alerts, although when I tried, my computer warned me the link  to www.usablight.org was not secure. Margaret Roach’s Tomato Troubles FAQs has some good descriptions and many helpful links. One of the links is to Tom Stearn’s “tomato hygiene” management method.

We had trouble with our paste tomatoes, and got excellent help from the Plant Disease Clinic of the Virginia Cooperative Extension. Sadly, some of our plants seem to have been victim of some herbicide drift or cross-contamination, despite our best efforts to run our garden organically. We don’t control what falls out of the air. Happily, the plants recovered from the stunted curling in of the leaves, and are starting to pump out good yields. I hate the thought that we will be eating slightly poisoned tomatoes, even though they are still much better than commercially grown non-organic produce.

Other great articles include one by Eric and Joanna Reuter about growing chestnuts, one by Gretel Adams about growing flowers without plastic, including the wonderfully simple idea of fastening C-clamps on the bottom of the hood over the tiller to mark rows in the soil. There are reviews of two farming phone apps, one for CSA farmers and one called BeetClock, based of Richard Wiswall’s Organic Farmer’s Business Handbook.

Growing for Market, Organic Broadcaster, using rainy days

June2016_cover_300 pxThe summer issue of Growing for Market (June/July) has been out for a couple of weeks. We’re having a very rainy Fourth of July, so that pushed my mind towards good reading material. Assuming you stayed home and didn’t join the millions on the roads.

This issue has an interesting article by Amy Halloran about sustainably grown food grains as an addition to the crop portfolio for vegetable and flower producers. Sometimes we’re looking to diversify our crops to help the rotation (thwart the usual pests and diseases), or to even out the workload over the year. Local artisanal bakers and brewers might be looking for locally grown grain, or you can sell small bags alongside your vegetables. One advantage of grains is that they have a good shelf-life, so you can bring them out to your CSA or you market when you wan to add something new and different. Heirloom grains and dry beans have appeal for those who want to return to their roots.

Eric and Joanna Reuter wrote a helpful farmers’ guide to applying for a SARE grant. They give a clear overview explanation, then a step-by-step guide to how to apply. They talk about how to design a suitable project, how to set it up, run it, evaluate and fit with the deadlines. They include an example of a SARE farmer-directed research project that changed their farm management. It was Kevin Cooley’s pilot project using supermarket baskets (factory seconds) to harvest, wash and store vegetables. The vegetables stay in the basket they’re picked into. It saves a lot of time and reduced handling.

Wendy Carpenter wrote a very useful article reviewing use of moveable high tunnels. Five years have passed since this idea really took off, and they are no longer “flavor of the month.” Unsurprisingly, there are pros and cons to using a moveable tunnel, and many cautionary tales. If you are thinking of buying a slideable/dragable tunnel, and especially if you are thinking of designing and building your own hardware, read this article first! Save money and tears! Like many people, I was intrigued by the idea of having a hoophouse that could have a summer home and a winter home. But after some reading and reflection, I’ve come down on the side of staying put, for us. We value a draft-free winter hoophouse (moveable ones can be hard to close up well.) I have been nervous enough when we have high winds – I don’t want to add to that uncertainty. And we have a crop rotation worked out that suits us. We gradually replace the winter and early spring greens with early tomatoes, peppers, squash. Our climate is warm enough that we don’t need it to grow these crops in the hoophouse in the height of summer – they do fine outside. Growers in colder climate zones like to use their tunnels for nightshades and cucurbits all summer, which can make crop rotation difficult. I can see the benefit they get from a moveable house. In high summer we grow a bean seed crop, which helps our rotation, improves the soil and pays its way. We do use a big sheet of shade cloth over the top when it’s hot.

Linda Hepler Beaty writes about adding a “WOW factor” to farmers market booths. Gretel Adams provides new information about growing lisianthus, a popular topic she has covered before. Theirs are grown in a hoophouse, using horizontal netting to keep the stems upright.


The Organic Broadcaster for May/June has been out (but I’ve been too busy to read it. . . ) it includes articles about industrial hemp farming, sprouted fodder grains, working on the National Organic Standards Board, transitioning to Organic, assessing the financial wisdom of buying machinery, the impact of warm season grasses on organic dairy cows, farming for wildlife with hedgerows (including elderberry and currants), a review of Lisa Kivirist’s book about women farmers Soil Sisters, farm safety for children, and there is the usual round up  of organic field days and events, news briefs, and classified ads. The 20 pages are packed!

Lisa Kivirist and her newest book. See this site for details of an August Soil Sisters event in Wisconsin.
