Workhorse Crops for September

Here we are with my monthly series of 14 Workhorse Crops (including two pairs). These crops are reliable under a wide range of conditions. My goal with this series is to help you become more efficient, productive and profitable (if selling) as you deal with another strange year. Maybe you are not at home as much as last year, or maybe your helpers have gone back to school, but you deeply appreciate growing your own food. You want less time-consuming crops and growing methods. You can use the search box to find previous month’s entries, such as August.

Workhorse Crops to Plant in September

In September in central Virginia, the heat is less oppressive, especially since Tropical Depression Ida washed by. The day-length is definitely shorter, soon we will be at the equinox with only 12 hours of daylight. Gardening is more focused on harvesting and less on planting. Food processing is at its busiest.

This month we will put our fall and winter garden plan into action. Plants take longer to mature from September onwards, so don’t delay any plantings. Try a few different dates, and keep good records, especially if you’re a new farmer or gardener, and improve your plan for next year.

In September we only have enough good growing conditions to plant 5 of our 14 Workhorse crops in central Virginia. Down from last month’s 8. We can still transplant cabbage, collards and kale, and sow carrots, and chard (or transplant the chard.)

Cabbage and Collards:

September is much too late for us to start cabbage, but we could still transplant early in the month, if we have transplants with four true leaves (3-4 weeks after sowing). If you only have bigger transplants, remove some of the older leaves until four leaves remain. This will help the plants survive by reducing evaporation (transpiration) losses. Collards can be sown here until September 15.

If insect pests are a problem, cover the transplants for four weeks, until they are big enough to survive. Nets are better than rowcover in hot weather, as airflow is better and heating is less. I wrote last month about ProtekNet Insect Exclusion Netting from Dubois Agrinovation.

Another advantage of nets over rowcover is that you can see what’s growing! Back before ProtekNet I found one year that I had been studiously watering a covered bed that was mostly galinsoga! It was quite big, and I had assumed it was greens!

Two weeks after transplanting, till or hoe around the plants. Four weeks after transplanting, remove the netting entirely, and hoe and till again. At that point you could undersow with a mix of clovers to be a long-term cover crop, unless you plan to plant an early spring crop in that bed.

Carrots

This is actually late for carrots but if you failed to establish them in August, hurry out and sow some early in September. You won’t get big carrots, but you’ll still get carrots! Hoe between the rows as soon as you can see them, because carrots grow slowly and fall weeds grow fast!

Once the carrots are 1” (2.5 cm) tall, hand weed, cultivate with claws (to kill weeds that haven’t even emerged yet) and thin to 1” (2.5 cm) apart. Simply pulling the weeds is not as good as also lightly disturbing the surface of the soil. Heavy rains can cause crusting, which makes it hard for seedlings to grow. Breaking up the crust lets air and water in. I have noticed that crops make a growth spurt after hoeing. If you think you might have carrot rust flies in your area, collect up all the carrot thinnings and take them to the compost pile, so that the pests won’t be attracted by the smell of carrot leaves, and move in to eat your carrots.

Later thin your carrots to 3” (7.5 cm) and weed again. That’s a September task, if you sowed in August. The tiny ones you pull out may be big enough to wash and throw in a salad. Before they develop the orange color they don’t have much flavor, but they are a treat for the eyes anyway!

Kale:

We grow Vates dwarf Scotch curled kale, the most cold-hardy variety I’ve found. I’ve tried every type of kale I could get my hands on, including some imported from Europe. Vates isn’t huge – we plant 4 rows 10″ (25 cm) apart in each bed. We want 6 beds of kale to over-winter, and there isn’t time to transplant it all. We direct sow, two beds at a time, every 6 days. We water the two newly sown beds, daily as needed, until the seedlings emerge.

Often we get patchy emergence in those hot August days, so we use carefully dug thinnings to fill gaps. Our goal is one plant every foot (30 cm). Our mixed direct-sow/transplant method requires less watering than if direct sown all at once and gives us a solution if we get patchy germination. September 15 is our last sowing date for kale for harvests in late fall and through the winter. We cover the beds with netting, until the plants are large, or the weather gets too cold for pests.

Kale makes some growth whenever the temperature is above about 40°F (5°C), which happens in our winters on many days, making this a valuable winter crop. We will also sow more kale in late January, to give us a spring crop.

Chard: Swiss chard can be sown here in August, and transplanted in September for a good fall harvest, with the option of overwintering under rowcover. It grows small leaves after only 35 days, and full-size leaves after 50 days. Chard is our poster-child insurance crop! So easy! So productive! It is not eaten by bugs, and does not have problems germinating in hot weather like spinach does.

You could direct sow chard in September and protect it for the winter, for a late winter and early spring harvest.

Workhorse Crops to Harvest in September

Eleven of our 14 workhorse crops can be harvested in September (also true in August, but now with one substitution!)

Beans can be harvested until the first frost (or later if we cover the beds with rowcover when a frost threatens). We also cover the bean beds (and squash, cucumbers, zucchini and other tender crops) whenever there is a chilly spell. This keeps the plants warmer and growing faster. Vegetable crops begin to take longer to ripen in September. It’s certainly true that pollinating insects can’t get at the flowers to perform their pollination services and make more beans, etc. But that doesn’t matter. We are more interested in fattening up the already pollinated beans!

Plenty of beans to eat in September.

Cabbage We eat about 50lbs (25 k) a week. Fall planted cabbage will be ready from September 25. We like Early Jersey Wakefield and Farao for fast-maturing cabbage.

Carrots: We generally hope not to need to sow carrots between June and the beginning of August, because carrots grown in hot weather don’t taste sweet and can even be soapy. If we did not grow enough carrots in the spring, we sow in June, or July and harvest those carrots about 2-3 months later (less time in warm weather, longer as the weather starts to cool in the fall). So, some years we harvest carrots in September.

Chard can be harvested whenever you want some. Snap or cut off some outer leaves and refrigerate them promptly. We use our Leafy Greens Mantra “8 for later” meaning that we make sure to leave at least eight of the inner leaves on each plant, as we harvest the outer leaves. With chard, we can take a couple more than this, but we do want to harvest at sustainable levels.

To overwinter chard in our climate, we cover the bed with rowcover on hoops. We can continue to make harvests into early winter. The mulch and rowcover help keep warmth in the soil, which keeps the crop growing.

Another method of over-wintering chard in reliably cooler climates, is to make a big harvest of all the sizeable leaves, just before the daytime temperatures are around freezing, then pile tree leaves, straw or hay over the bed for the winter. Covering the whole stack with rowcover is even better. Our winter conditions are too variable for this – we get cold spells interspersed with warm spells in almost every month, causing the plants to make some growth among the mulch.

The outdoor killing temperature for unprotected Bright Lights chard is 22°F (–6°C); red chard survives down to 15°F (–9.5°C) and green chard to 10°F (–12°C).

Collards can be lightly harvested in September, if you started them early enough. What’s more likely true for us, is being able to harvest leaves of senposai. No, not the same as collards! But it fills the same spot on the dinner-plate – fresh leafy greens. It’s been a long summer with only chard, this year, as we were short of spring cabbage, and don’t have any fall cabbage or broccoli yet.

Potatoes: We can plant potatoes between mid-March and mid-June, leading to harvests in July-October. It’s as important not to leave potatoes baking in the sun as it is to protect them from frost, both when planting and when harvesting. Read more about potato harvest here.

Our March-planted potatoes are in the root cellar. By mid-September, we need to cool the cellar to 60°F (16°C)

Sweet Corn harvest is still going strong. Sweet corn is ready to harvest about three weeks after the first silks appear. Some growers say you should harvest daily, but we find that 3 days a week is often enough, and gives us a nice amount from our 1050-1325 ft (320-400 m) plantings to feed our community. We sow sweet corn six times, for continuous harvests from early July to mid-October.

Corn is ready when the silks are brown, not before! If they are brown, and the ears are plump and filled to the end with kernels, take a closer look. Mature ears stand away from the stalks. If you are still learning, slit the husks at the side of the ear with your thumb nails and look at the kernels. (Don’t puncture the husks on the topside of the ear as the dew and a million tiny beetles will get in and make a mess.) The kernels should be a bit square and fairly tight-packed, not round and pearly with rounded diamond-shaped spaces between them. An opaque, milky juice will seep out of punctured kernels. If your sample ear wasn’t ready, push the husks closed over the ear and wait a few days.

Be sure to shade your corn after harvest and get it cooled as soon as possible, as the flavor deteriorates if it sits around.

Tomatoes are cranking out their fruit but starting to look “back-endish” – spotty, and smaller. To minimize the spread of fungal diseases, wait for the leaves to dry in the morning, before harvesting. We plant maincrop tomatoes (sown in mid-March) and late tomatoes (sown in mid-May). This way the late ones peak after the maincrop, and keep the plentiful supply going longer. This year our late bed includes a few Black Cherry and Sun Gold cherry tomatoes as well as lots of our standards: Tropic, a heat-tolerant, disease-resistant round red one, and Jubilee, a lovely flavorful orange that is also a feast for the eyes. This year I have been particularly impressed with its healthiness – the fruits are reliably unblemished and do not readily split. Truly a workhorse variety!

Watermelon harvest is peaking. They don’t ripen further after harvest, so get good at determining watermelon ripeness. I wrote about that in my August post. An unripe watermelon is a sad waste, as most plants only produce two melons.

We store our watermelons outdoors, under the eaves of the house, where they will stay in good shape for a few weeks. We used to store them under the trees further from the building, but the squirrels learned to bite their way in, and taught each other the trick!

When we have enough watermelon harvested (500-600), we roll up the drip tape and disk the plot, to get a good stand of winter cover crops. We use winter wheat and crimson clover if before October 14. I’ll address this more next month. We used to try to harvest every last watermelon until the year I realized that we can only eat so many, and that watermelons in October are of limited interest. Good cover crops are important for taking care of the soil mini-livestock.

Winter Squash harvest happens once a week throughout September and October. This is next week’s blog topic. Winter squash is very rewarding to grow, providing high yields for not much work. Stored winter squash can provide meals all winter and also in early spring when other crops are scarce.

ATTRA has a very good publication Organic Pumpkin and Winter Squash Marketing and Production. Add it to your winter reading if you plan to grow winter squash next year!

Zucchini and summer squash are still being harvested every day. Our last sowing was August 5. We harvest beyond the first fall frost, by covering that last planting with rowcover on chilly nights. See above, under Beans for our thinking about fattening up the last fruits.

From storage: spring cabbage, carrots, garlic and potatoes; watermelon from under the trees or the roof overhang.

Workhorse Crops Special Topic: Garlic Storage

Between late September and early October, we move our stored garlic from the basement to the walk-in cooler. the garlic was stored in the basement from June to the end of September, where the temperature was above 56°F (13°C) which is a perfectly fine storage temperature for garlic. Once the basement gets colder than that, we move the garlic to the refrigerator, where it will be below 40°F (10°C). The temperature range of 40°F to 56°F (10-13°C) is where garlic sprouts readily.

Workhorse Crops for June

Workhorse Crops for June

I’ve chosen 14 Workhorse Crops (including two pairs) to focus on at the beginning of every month, until April 2022: These are crops that we can rely on under a wide range of conditions. Some Workhorse Crops are easy to grow, some pump out lots of food, some are “insurance crops”, some are especially profitable (for those growing for market), and watermelons are the circus pony among the workhorses, I admit, but we all need fun!

I intend for this series to help growers who want to become more efficient, productive and profitable (if selling) as we emerge from sheltering at home and expand our lives again. Don’t give up growing your own food, just choose some less time-consuming ways to do it.

Workhorse Crops to Plant in June

June is another busy planting month here in central Virginia. Next month the heat strikes hard, and the daylight starts to get shorter, but this month we are still climbing the hill of the year. Ten of our 14 Workhorse Crops can be planted in June.

Beans: We sow bush beans every few weeks to keep up supplies of tender beautiful beans. See the Special Topic section for info about Succession Planting, to help you determine when and how often to sow beans and other short-lived warm weather crops. Also see the Special Topic section to read how we control Mexican Bean Beetles that used to destroy our bean plantings. Click this link to read about soaking bean seed, using inoculant, sowing through biodegradable plastic mulch using a jig, sowing sunflowers in our bean rows as place-markers when harvesting.

Carrots: I wrote a lot about carrots in the past year, when the monthly series was on root crops. See this post on preparing beds for sowing carrots, and weeding and thinning. Check out this post on flame-weeding, if you plan lots of carrot-growing!

We sow carrots in late February, then twice in March, once a month in April and May and after that we’d like to not sow more until the beginning of August. Carrots grown in hot weather don’t taste that good: there’s little sweetness and too many terpenes (the compound that in small quantities gives carrots their distinctive carrotiness, but can be overpowering if too strong.) But home-grown hot weather carrots are still better than jet-lagged travel-weary carrots from afar. You could use shadecloth over the beds. If we have not grown enough carrots by the end of May to see us through to October, we sow in June, and even July if we must.

Chard: The perfect insurance crop! We use chard for fresh greens in summer, when spring kale, collards, broccoli and cabbage have long bolted and been turned under so we can plant something else. We transplant our chard into a hay mulch in late April. Organic mulches help keep the soil cool during hot weather, so are very helpful for leafy greens. This crop will be in the ground until mid-winter, and mulch will keep back most of the weeds.

Chard provides leafy greens all summer whenever you need them, and you can ignore it when you have plenty of other vegetables! As a biennial, chard will not bolt the first year (unless stressed by lack of water). I’ve noticed the red chards bolt more easily than the green ones. I suppose red crops are a bit stressed already, as they are short of chlorophyll, compared to the green ones, making photosynthesis harder work.

Potatoes: I wrote a special series on potatoes last year. Click the link to access the whole series, starting with planting in April. Here we plant in March and June. For our June-planted potatoes, we pre-sprout the seed potatoes for just two weeks (shoots grow quicker in warm weather than in early spring). To protect the planted potatoes from the summer heat, we hill immediately after planting, even though we can’t see the rows! Then we unroll big round hay bales down the field to cover all the soil. Potato shoots grow strongly, and can make it up through the extra height of the hills/ridges and through the 3” (7.5 cm) of hay. After about 16 days, we walk through the field, investigating spots where there is no sprout. We call this task “Liberating the Trapped Shoots”. Often the problem is just an overthick clump of mulch, and the shoot will be quite literally trapped (and completely white). We simply let he shoot see the light, and redistribute the over-thick mulch.

Sweet corn: we make 6 sowings of sweet corn, to harvest from July 4 to mid-October. We are well into corn-planting time, which continues until mid-July, when there are not enough warm days left in the season to mature another sowing. Remember: don’t plant a mixture of different corn genotypes, and don’t plant Indian corn, popcorn or any kind of flint or dent corn within 600′ (180 m) of your sweet corn. This leads to very disappointing starchy corn. We grow only sweet corn in our garden, to avoid this problem.

Sweet potatoes: I wrote a lot about planting sweet potatoes in 2020. Wait for the soil to warm before planting out your sweet potato slips, they don’t grow well if too cold. We plant ours a couple of weeks after the last frost, around the time we transplant peppers and okra. In early June, we replace any casualties, if needed, to fill out the rows again. This year we have a beautiful looking patch, with rows of healthy plants on ridges, with biodegradable plastic mulch. We have a solar-powered electric fence to deter the deer. My latest worry is groundhogs, who can slip right under the electric fence. They haven’t yet, but I expect they will, if we don’t catch them first.

Tomatoes: In mid-June we plant a bed of late tomatoes, to boost the yields when the maincrop beds start to pass their peak. We planted our main crop tomato beds at the very beginning of May, and they’re looking quite good.

Here’s a post about planting tomatoes in our hoophouse. We use the same techniques in the hoophouse and outdoors. We transplant one row of tomatoes down the centerline of a 4ft (1.2 m) bed, 2ft (60 cm) apart. Once the weather has settled so that we’re confident we won’t need rowcover any more, we stake and stringweave. We install a steel T-post every two plants (4ft /1.2 m) apart and start stringweaving when the plants are about 12ins (30 cm) tall. I’ll say more about stringweaving next month.

Watermelons: As I explained in May, I gave watermelon a “Circus Pony” place among the workhorses! They’re not easy, therefore not reliable, but they provide so much pleasure when they do grow well. We transplant our watermelons, to get ripe ones as early as possible.

Watermelons grow very well on black plastic mulch, which warms the soil as well as keeping weeds at bay. The first year we switched from using hay mulch to biodegradable plastic mulch, we were astounded to get ripe melons a full month earlier!

If you want to use organic mulches for warm weather crops, don’t do it immediately. Wait till the soil warms through. This year we made that mistake, then we had late cold weather and the transplants all died. We’re going to experiment with station-sowing seeds directly in the gaps. Station-sowing is a technique of putting several seeds in the ground at each spot (station) where you want one plant to grow. Rather than making a furrow and sowing a row that needs thinning later. It’s a good technique for remedial work (ahem!), or if growing very expensive seeds, or for crops you are not familiar with, such as parsnips. You see several seedlings all the same and can be pretty sure it’s the thing you planted.

Watermelons can be planted from seeds when the ground has warmed to at least 70°F (21°C). On average, it takes about 85 days for Crimson Sweet seedlings to mature and produce ripe fruit. This is late for us to sow watermelons, and we certainly won’t get early ones this year, but we could get them in September. Better than none.

I described transplanting watermelons last month, if you need that info.

Winter squash are a true workhorse, and can still be sown here early in June, provided we don’t sow the slow-maturing ones like the gigantic Tahitian Butternut. Aim for harvesting in September and October and count back to see how many days you have until you want to harvest. Then choose the varieties that will have enough time. You can also transplant winter squash if you need to. We did this once when our fields flooded. It worked out fine.

We mostly grow Butternuts, Moschata types that store best. This is the type to focus on if you want squash with no damage from borers or cucumber beetles. The tougher stems are better able to repel invaders. They need warm growing temperatures above 60°F (16°C).

See last month’s post for more about sowing winter squash, and for other kinds of winter squash, such as some Maxima squashes that store quite well and have relatively high resistance to squash bugs compared to others in this group, and Pepo squashes, suitable for storing a few weeks only

Zucchini (courgettes) and summer squash: another crop type that we succession sow, to get a continuous supply. More about succession planting below in the Special Topic section. We make five or six plantings, each one half yellow squash (Zephyr, Gentry) and half zucchini (TenderGrey, Noche, Golden Glory). We grow our earliest squash in the hoophouse, setting out transplants at the beginning of April. Our first outdoor crop is also from transplants. After that, the soil is warm (60°F/15.5°C) and we direct sow. The time from sowing to harvest is only around 42-54 days.

After transplanting or sowing, we hoop and cover the row with insect netting (rowcover works if it has no big holes). We have many bugs that like these plants, especially the striped cucumber beetles, so we keep the rows covered until female flowers appear. At that point we need the service of the pollinators, unless the squash is parthenocarpic (sets fruit without pollination). We pack away the covers, hoe and thin the squash to 24” (60 cm). It would be better to thin sooner, but we rarely find the time.

Workhorse Crops to Harvest in June

We have mnemonics for harvesting: Monday, Wednesday and Friday might be the crops beginning with the plosive Ps and Bs: peas, beans, beets, broccoli, blueberries etc. Tuesdays, Thursdays and Saturdays would be the crops beginning with the hard K and G sounds: kale, corn, carrots, collards, cabbage, garlic scapes etc.

Other crops like asparagus, lettuce, cucumbers, summer squash and zucchini we harvest 6 days a week. Some, like cabbage, we harvest twice a week.

Asparagus can be harvested here until early in June. Every day for the 8-week harvest period, snap off at ground level all the spears above a certain length. We chose 7” (18 cm). This task is best done first thing in the morning, when the spears are crisp. Daily harvest will also remove asparagus beetle eggs, controlling the pest level.

Cabbage is ready here from late May until mid-July. We store enough to feed us until we start harvesting fall cabbage. An early sowing of fast-maturing varieties (like Farao or Early Jersey Wakefield which can be ready in only 60 days) can be followed by harvests of slower varieties. When a cabbage is ready for harvest, the head is firm and the outer leaf on the head (not the more horizontal wrapper leaves) will be curling back. For cabbage to store to eat over the summer, cut with a strong knife and set it upside down on the nest of leaves to dry a little. Come back along the row with a net or plastic bag and gather up the storage quality cabbages to refrigerate. Gather any lower quality cabbages to eat soon. If you would like to get another harvest from the same plants, cut criss-cross into the stump. Small “cabbagettes” will grow and can be used raw or cooked. They won’t store.

Carrots can be ready about three months after sowing in spring, although you can get thinnings for salads sooner. Read here about harvesting carrots.

Chard is ready for harvest as soon as you decide the leaves are big enough. Simply snap or cut off some outer leaves and stand them in a bucket with a little water until you cook them. For a sustainable rate of harvesting with chard, always leave at least 6 of the inner leaves to grow.

Garlic harvest time will be soon if not already. I wrote about garlic last week.

Kale and collards can be harvested until they are bolting, as long as the flavor is acceptable. Our spring-planted ones are not bolting yet, but the fall-planted ones were tilled in a couple of weeks ago.

New potatoes could be dug here during June, if you don’t mind reducing the final yield. The flavor of new potatoes, with their delicate skins, is very special. As a child, I ate them boiled with mint, and topped with some butter.

Tomatoes start to ripen this month. Our hoophouse tomatoes have started to yield a small amount of Glacier, Stupice, Sungold and Amy’s Apricot.

Zucchini and summer squash are ready from the hoophouse early sowing since about May 20. We are now (June 2) harvesting our first planting of outdoors. We harvest every day to the fall frost (or beyond if we remember to cover that last planting with rowcover on chilly nights.).

Succession planting, and Mexican bean beetles

Succession planting is a topic I have often presented at workshops, so rather than give you more words, I’m giving you the slideshow from 2019. Towards the end it includes information about dealing with Mexican bean beetles.

My presentation on Crop Planning to the CSA Expert Exchange Online Conference on Friday 3/7 went well, after a short delay due to slow website loading. Joys of rural living! I just learned that our Internet runs slow on rainy days because the water in the soil affects the underground cables. A s a farmer, I’m very used to considering the effects of the weather, But I never would have guessed this one. Now I realize I jinx myself when I work outside in nice weather and do my desk work while it’s raining!

This week has been challenging in the garden because of snow followed by very wet soil. On Monday we managed to transplant a bed of spinach and the first week’s round of lettuce. That felt like great progress! Even though it is a month later than we would “normally” hope to do those tasks! We chose to work on the driest section of the raised bed area. Before that we had been weeding the grapes and spreading compost. Having some perennials to take care of makes good use of our time in the winter, early spring, and whenever cultivated soil is too boggy to step on (in).

These considerations are all part of a list we keep to help us choose tasks suited to the conditions, so we can make best use of our time without doing damage. A lot of our garden work is done on 3 or 4 hour shifts with up to 11 people. The honcho needs to be on the ball to keep all those people gainfully employed! Our honchos/honchas are the more experienced people, and will usually prepare for the shift beforehand, making a list of possibilities.

Some of the shift time is harvesting (only spinach currently, apart from getting potatoes from the root cellar and sweet potatoes from the basement). That’s our top priority. We try to get some harvesting done even if it’s very cold or raining lightly. The crops that wilt fastest get picked close to the end of the harvesting period, so they don’t deteriorate while we get other crops.

We have a Task List for the week, and our sequence of priority is generally harvest, plant, mulch, prepare beds for planting, hoe, hand-weed. “Prioritize planting during the planting season” is one of the mantras we embrace. Sometimes other factors come into play. A new member pointed out that all my answers start with “It depends. . . ”

We try to do the more aerobic jobs (especially jobs involving shovels) in the coolest part of the shift, or on the cooler days. We also try to offer each person some options, because people do better when doing tasks they prefer. Sometimes we just have to grin and bear it: “This is the job we need to finish today.”

We are often including visitors in our work, so we need to make sure we mix up members and visitors on each task, so that visitors get enough directions and help. We also need to check in to see how they’re doing with the heat/cold and level of physical activity. We don’t want them to collapse! We also need to be firm about pulling them off a job if they are causing damage, and trying to find some other task that might suit them better.

Having the entire crew finish the shift at the same time is complex choreography! Putting tools away as we go along helps reduce a mammoth task at the end, although having some people cleaning and storing tools as the finish time approaches can be a good way of evening out the workload. The honcho needs to pace the planting, watering and rowcovering. It’s no good transplanting 500 feet if you don’t get it watered and covered before leaving the scene.

Sometimes it’s easier to start everyone on a big hoeing or weeding project, then leave an experienced person in charge of the straightforward task and most of the crew, while you pull out a couple of people to get a complicated task started. Next add more people once it’s up and running. Or send one or two experienced people over to set up, and then send more crew over as the set up work is done It’s awful having 9 people stand there while you try to figure out how to do a planting!.

We have contingency plans for specific situations:

If the day is likely to be very hot, have an “aerobic segment” at the beginning of the shift and get the physically taxing tasks done first (especially anything involving shovels).

If the morning starts out with a heavy dew, postpone harvesting cucurbits, nightshades, strawberries and legumes until the leaves dry, to reduce the spread of disease.

After heavy rain: mulched perennials (fruit and asparagus) are the easiest places to work without getting bogged down. Don’t work in sinking mud, it compacts the soil, which means the plants go short on air, and the soil will be slower to drain after future rains.. Standing on boards is an option for harvesting or planting..

If heavy rain is expected and you might have to stop in a hurry, do weeding, not planting. Don’t hoe if it’s about to rain, it’s a waste of time. Hoeing is best done in an area that won’t get irrigated that night. Likewise don’t leave pulled weeds on the beds before rain. They’ll re-root.

If you feel frazzled, choose a big simple task lots of people can do, like weeding strawberries, or hoeing corn. Or choose two tasks geographically close, so it’s easy to keep an eye on everything happening.

Book Report: Cindy Conner’s Grow a Sustainable Diet

Book Report

Cindy Conner: Grow a Sustainable Diet: Planning and Growing to Feed Ourselves and the Earth. New Society Publishers 2014.

“This book will help you learn how to calculate how much food you need and how much space you need to grow it, ” proclaims Cindy Conner. It is written for the backyarder or homesteader who takes food self-sufficiency and ecology seriously. To grow food crops without depleting the soil or bringing in outside inputs, for instance, you will need to dedicate 60% of your land to growing compost crops or cover crops. This challenge is not for the faint-hearted. But here you have the leader-in-a-book, you are not going it alone.

Cindy explains what she means by a sustainable diet and includes a fascinating exercise “What if the Trucks Stopped Coming?” – where would you go to get all your food within 100 miles from home? Within 50? 25? What foods would you be eating and what would disappear from your life? Would the existing farmers be able to supply everyone’s needs locally, or would you need to provide more for yourself and your household? What would your priorities need to be? Your first thought might be that you’d need to make secret stashes of food, and get guns to keep away your hungry neighbors. Cindy says she doesn’t believe guns will keep hungry people away and the better answer is to act from compassion, and work with your neighbors to meet whatever the future brings. None of us can survive without community, so let’s make sure our community is strong enough to meet the challenges.

In the Garden Maps chapter, Cindy explains how to divide the available garden space up into smaller plots or sets of beds, increasing your ease of access without losing a high percentage of potential growing space to paths. Beds curved along the contours will reduce rainwater runoff and erosion. On the other hand, straight lines are easier to hoe quickly. Design your garden to suit the ways you use the space – how you get to the chicken pen, or the compost pile. Permaculture design principles have influenced Cindy’s choices.

Next you can chose your crops. If all your nutrients are to come from your garden, you will need to pay attention to growing enough calories. otherwise you’ll lack the energy to get to the end of the season! Cindy reports that potatoes, Jerusalem artichokes, sweet potatoes, parsnips, salsify, leeks and garlic are on the list of calories/area. Personally I can’t imagine getting a lot of calories from garlic. Besides the overwhelming flavor there is the issue of the work involved – garlic is labor intensive at certain times of year. Leeks similarly don’t seem a good source of calories per pound, even if they are good per square foot. And winter squash are easy to grow and surely full of calories. They do take space to grow, but I wouldn’t rule them out for that reason alone.

If you grow a lot of the calorie crops already mentioned, you will also be growing a lot of protein. Legumes produce more protein, at the cost of needing more space than the high calorie crops above. Beans, peanuts, peas can be interplanted with other crops to get that protein in the most space-saving way possible. Grains provide amino acids that are complementary to those in legumes, and the straw of grain crops is valuable for mulch or compost-making. Calcium is vital for bone health and there is plenty to be found in leafy cooking greens. A little oil or butter on the greens will help assimilate vitamin D, which is as important as calcium.

Oils and sweeteners are the two space-hogging challenges when it comes to food self-reliance. Sunflower and pumpkin seeds and peanuts, whether eaten whole or pressed, supply oil, as can some tree nuts. The home-grown vegan diet would be short on oils. Those who drink milk and eat eggs get some fats that way, easier by far. Some fruits store for out of season use. Honey, maple syrup and sorghum syrup can be home-produced, although you’ll be shocked the first time you see how much land and how much work goes into the vegan options. (Honey is made by small furry animals, it isn’t vegan.)

The question of How Much to Grow is important, if time, effort and land are not to be wasted. Locally-adapted varieties and your personal culinary preferences, as well as potential yields per area will influence your planning. After your first year, your record-keeping will be your guide to making improvements.

To keep your garden productive year after year, you will need to feed the soil. You can do this by bringing in organic materials as mulch or to contribute to your compost. If you worry about the reliability of the supply from outside, or whether it is contaminated with herbicides or car exhaust, or whether its production is truly sustainable, you’ll want to be as self-relaint in that department as in the rest of your enterprise. You could grow mulch crops (straw or hay) as part of a bigger farm, in rotation with grazing animals. Or you could grow all your compost and mulch crops within the boundaries of your garden.

Compost is a priceless soil amendment, adding not just organic matter and the basic nutrients but also a fine collection of microbes. There are almost as many ways of making compost as there are compost-makers. Cindy prefers the cool, slow method (using a relatively high proportion of carbon materials to nitrogen materials), in order to “farm” the particular mix of microbes that result that way. The annual pile is part of her garden rotation, built on top of one of the beds, starting in the fall. The next fall, after that compost is spread on the garden, winter rye is sown.Next spring this is cut and left as mulch. The rye has scavanged any compost left from the pile and returns the nutrients to the soil as it decomposes around the corn seed (sown into the mulch).

Earlier, I said you need to plant 60% of your garden in compost crops or mulch, to have a sustainable system. Two thirds of that space would be in carbon crops and one third in nitrogen crops. Happily, some of the compost materials will be grown as a by-product of a food crop (corn stalks are a good example). The book leads you through the process of identifying suitable crops, and best of all, provides a worksheet to help you determine Bed Crop Months. For each bed, from your plan you determine how many months that bed has food crops and how many months compost crops (remember that one crop can be both!) Winter cover crops really help achieve the goal! After considering each bed, you tally up and see if you need to find more niches for compost crops.

All the work in Cindy’s garden is done by hand, including cutting down cover crops, and this is carefully explained. The space is used very intensively, often planting several crops in the same bed to get best use of the space, and so that one can take over from another later.

Scheduling so your crops mature when you want them is the next big task, followed by planning a good crop rotation,and fitting everything into the space you’ve got. “Lay out your intentions, stay flexible and keep learning.” More worksheets are provided to help you.

Sections on looking after your seeds, on including animals, on food storage and preservation and on sheds, fences and other support systems follow. About animals: “You can plan a diet of only plants, but you would be hard pressed to fill all your nutritional needs without taking supplements, which are not part of a sustainable diet.” Hear, hear!

Cindy’s book will set you on the path to providing healthy food for your household without depleting the Earth in the process. Her conversational style will give you confidence as she breaks complex ideas into manageable steps. Beginners are talked through the process step by step. Cindy’s years of teaching college shine through. One reframing exercise I liked was this “if you have thought of weeding as drudgery, something you have to endure [b]egin to think of weeding as a harvest of materials for the compost pile.”

Twin Oaks January Calendar – Starting a new garden season

Yes, really! On January 17, I sowed flats of cabbage, lettuce and mini-onions (cipollini), and the cabbage and lettuce are already up. Onions usually take 10 days, so I’m not surprised not to see them yet. It’s fun to see new seedlings, even though my energy isn’t ready for taking on another growing season yet. I’m still enjoying hibernation!

The cabbage varieties are Early Jersey Wakefield, a quick-growing small pointy-head open-pollinated variety, and Faroa, a quick-growing fairly small round hybrid that has been very reliable for us. These are for a bed of early cabbage, to eat after our stored winter cabbage is all gone. We’ll sow our main-crop cabbage on 2/7, in much bigger quantities.

I sowed two lettuces: reliable old Salad Bowl and the unusual Cracoviensis, a pink veined sturdy leaf lettuce, that we have found is only useful for us at this first sowing. It bolts too easily once it gets even faintly warm. It tends not to get bitter even when bolting, but our diners aren’t going to believe that!

We’re also still busy with various stages of our garden planning. yesterday I updated our harvest calendar, which tells our cooks which crops they can expect when, and also our food processing calendar to tell the food processing crew when to be ready to tackle large amounts of broccoli, beans or paste tomatoes, for example. I’m part way through revising the document we call our garden calendar, which is really a month-by-month task list. If you were following this blog in the fall, you’ll remember some of those monthly garden task lists. We’ve planned which crops are going in which of the 60 permanent raised beds and identified the ones we need to spread compost on and till first. And then we twiddle our thumbs – lots of rain last week (and a bit of snow) mean it will be a couple more weeks before the soil is dry enough to till.

Here’s our short Twin Oaks Garden Task List for January:

Planning: Prune the catalogs, do the filing, consolidate notes on varieties and quantities.

Week 1: Finalize seed orders, if not done in December. Revise Seedling Schedule using seed order.

Week 2

: Revise Outdoor Planting Schedule. Plan labor needs for the year.

Week 3

: Revise Raised Bed Planning Chart. Plan raised beds for Feb-June.

Week 4: Revise Garden Calendar, Lettuce List and lettuce Log.

Order Bt, spinosad and predatory beasties, coir. [sweet potato slips for shipping 5/12-5/17 if not growing our own]
Repair greenhouse and coldframes and tidy. Check germinator-fridge and heat mat. Repair flats, and make new if needed. Make stakes. Clean labels.

Check equipment: rototiller, discs, and mower – repair or replace as needed. Repair and sharpen tools.

Freeze out greenhouse to kill pests, or spray with soap or cinnamon oil every five days. Import ladybugs.
Check potatoes, sweet potatoes and squash in storage.

Mid-Jan: In greenhouse sow lettuce #1, early cabbage, mini-onions, early broccoli, onions.

Late Jan: In greenhouse sow lettuce #2, scallions #1, spinach, tomatoes, peppers for hoophouse
Plant small potato onions, 4-5″ apart, ½-1” deep, in a mild spell. Remove mulch to plant, then replace it. Plant shallots & mulch.

Perennials (see November list). Weed blueberries, raspberries, asparagus (spread compost), grapes, rhubarb, strawberries. Add soil amendments, fertilize (not strawberries) and mulch. Prune blueberries, (take cuttings if wanted). Fall raspberries: cut all canes to the ground, remove canes from aisles. Summer raspberries: remove old fruiting canes & canes from aisles.

Harvest: (Chard?), collards, kale, (senposai?) spinach, leeks, (Yukina Savoy?).

Turn Here Sweet Corn, by Atina Diffley. Book Review

This new book (published by the University of Minnesota Press) offers a real-life organic vegetable farmer’s memoir. Normally, I look for inspiring reading during the winter, to refresh myself for the next farming season. This book, however, is a perfect mid-summer revival aid for farmers and gardeners flagging in the heat. It gives us perspective on our troubles as we read of Atina’s and husband Martin’s struggles with wild weather (hailstones the size of B potatoes!), continuous hard work, and land lost to developers and threatened by a pipeline. The immediacy of their powerful and tender story and Atina’s decision to stand up and become a leader for what she believes in gives us inspiration. We can feel validation of our work as organic vegetable growers as we read that 1¼ acres of kale can produce 182,000 servings, and if our marketing is as good as the Diffleys’, we can sell them all within 42 miles of the farm! Organic farming sequesters 15-28% more carbon than industrial farming, with a 33% reduction in fossil fuel use.

Atina and Martin owned and operated Gardens of Eagan (one of the first certified organic produce farms in the Midwest) from 1973-2007, so you can be sure Atina knows farming! Starting as a confused teenager (as many of us do), Atina grew into a strong, committed passionate leader of the organic farming movement. Her descriptions of the beauty, deep satisfaction, multiple stresses and sheer exhaustion of farming ring so true. She talks about the meaning in the daily life of organic farmers, of investing in the soil life, creating balance, seeing the potential of each field, and bringing that out. “Dirt is just soil that’s out of place. Soil has structure. Dirt does not.”

Early in the book, you might wonder if she’ll ever make it as a farmer, but her determination and perseverance, and the quality of attention she brings to what happens on the farm ensure her success, and our gripping reading. The Diffley family farm is lost to developers, who carve and churn up the soil even while Atina, Martin, their two children and their crew rush to harvest their crops. They decide to piece together a farm from patches of land they buy and rent, until they find the perfect farm to buy. Being itinerant farmers is no easy choice, and requires exceptional organizational skills.

One of their organizational strengths comes from using Holistic Management tools learned at a workshop. She and Martin each write “quality of life” statements, answering the question “If we lived perfect lives, what would it look like?” Each winter they quit farming for a week, party and relax in clean clothes, with clean fingernails. Even talking about the weather is an “illicit act” during the Quitting Week. Then they state their goals for the year and recommit. When they farm again it is a conscious choice. Decisions have to fit their quality of life statements.

Atina says: “I have the same nightmare every winter. If I think about everything it takes to pull off a successful season, it seems impossible . . . [but] if we have a plan in place and I stay in the present, then the work is manageable. . . I just have to remember not to look too far ahead.” Exactly the same is true for me, maybe for you too.

One year they decide to simplify their crops and cut a deal where each picks a crop to drop. Goodbye to potatoes, onions, winter squash, leeks. Sort of. Atina admits that she and Martin then each sneak some winter squash in, unable to completely let go of the experience they have gained in growing this crop.

This amazing book also has gems of practical information embedded in the story, and they’re worth noting. Techniques include the use of farm micro-climates (the first place the purslane germinates is the best spot for early tomatoes and melons); moving flats of aphid-infested seedlings out into the center of a field of vetch for the day, to have the insects in the vetch feast on the aphids; accepting up to 50% defoliation of broccoli plants between the six-leaf stage and heading, because it will not decrease the yield; reducing the chance of aphid-vectored diseases in a squash planting by sowing a “toothbrush strip” of wheat around the perimeter (when the aphids chew on the wheat it cleans the viruses from their mouthparts, so the squash stay virus-free).

The farm grows in size and complexity each year, with a bigger work crew and more refrigerated trucks. They also develop a massive supportive community of consumers and produce retailers, which is to prove its worth as the story develops. When the Diffleys find their new farm, they can finally set the washing-line poles in concrete. But a big cloud comes over the perfect horizon – Koch Industries claim eminent domain to route their pipeline through their farm. Atina fights this, not just for their farm, but for other organic farmers too, establishing a protocol for safeguards to be taken if organic farm soil and wildlife habitat is disrupted.

The normal legal process for a farm trying to prevent a pipeline across their land involves proposing other people’s farms as possible alternative routes. This process divides us and causes each of us to need to compete with each other and fight individually. Atina Diffley created an Organic Appendix to the Agricultural Impact Mitigation Plan (AIMP) that is legally required when farmland is dsirupted. Atina and her legal team got the pipeline company to accept that (in the words of Dr Deborah Allen) “The losses to an organic vegetable farm from diminished soil quality are of a different character and order of magnitude than on a conventional crop farm.” Healthy soil is necessary for a successful organic farm. By creating this Organic Appendix and getting the pipeline company to accept it, Atina made something other organic farms could also use to prevent eminent domain devastation on their farms. It could also encourage other farms to transition to certified organic and benefit from the Appendix. Far from falling for the individual solution and fighting only for her farm, while further jeopardizing other farms, Atina found a way to unite with other organic farmers in fighting the assault.

This mixture of heart-breaking and encouraging is what makes the book so engaging. Atina tells us: “Every winter I do recover from the season’s exhaustion, but if I push too far, I won’t. As we age, personal balance will require more consistent time for renewal.” In keeping with her wisdom, after 35 years of farming, Atina and Martin retired from active farming to become educators and consultants about organic farming.

Potato Planting and Carol Deppe’s Writing

A ladybug on a potato leaf, looking for pests to eat — A ladybug on a potato leaf, looking for pests

We’ve just planted our second crop of potatoes for the year. At 3450 row ft (about a quarter of an acre), this planting is a bit bigger than our March planting. We aim to grow a whole year’s worth of potatoes for a hundred people. Planting in June has several advantages – for us the main one is that we can store this harvest in a root cellar over the winter, without using any electricity to control temperature. If we planted our whole year’s supply in March, we’d harvest in July and have to store them over the summer, and then all the way round till the next July. It’s also nice to split the work up into smaller chunks.

Up until this spring, we made furrows for our potatoes and covered and hilled them using a BCS 732 rototiller (or walk-behind tractor, as the retailers prefer to designate it). This is doable, but labor-intensive. This year we set up a toolbar on the tractor with sweeps to make furrows, and then discs to form hills. It’s been a learning process, with some teething troubles, but I do think it’s the way of the future for us. (I just don’t have the stamina for all the rototilling any more!).

Compared to using the rototiller, the tractor needs a lot more space to manoeuver. We were lucky in having an area of cover crops next to the potatoes for this planting, so we could run over the edge onto “next door”. In the spring planting, we had a hydrant in the middle of the patch. that’s a minor problem with the rototiller, but a bigger problem with the tractor. Keeping the row spacing tight is harder with the tractor, and in the spring, we ended up with some wider spacings, which lead to more weeds than usual, and poorer hills. This week (our second time using the tractor), we managed much better row spacing. Next year, we’ll allow more space to turn the tractor, right from the planning stage.

Another “surprise feature” this time, was that it rained right after we’d planted (yes, before we’d covered the potatoes). The forecast had suggested a small chance of showers later in the day, but the 3/4″ drenching was a complete surprise! So we had to wait two days for the soil to dry out enough to take the tractor again. The soil was clumpy, but not impossible. Probably we could have covered and hilled sooner with the rototiller, as it weights less, and compacts the soil less. And the soil would have ended up with a finer texture. Overall I think the trade-offfs of using the tractor are worth it.

The potatoes came to no visible harm sitting in their furrow for two days. We had pre-sprouted them, so the sprouts grew a bit bigger and greener. Luckily we didn’t have extremely hot temperatures those days.

Recently I learned some new information about ideal soil temperatures for potato planting. This came from a workshop on Sustainable Potato Production by Rusty Nuffer at Southern SAWG in January 2012. In spring, wait for soil temperatures to reach 50F (10C) before planting. In summer, the ideal soil temperature is 60-75F (15-24C). Ours was 70F (21C). It’s possible to pre-irrigate to lower the soil temperature in summer. (And hopefully nature won’t mid-irrigate for you as it did for us this week!)

Carol Deppe, author of the wonderful book The Resilient Gardener: Food Production And Self-Reliance In Uncertain Times, has written a very interesting article The 20 Potato a Day Diet versus the Ne arly All Potato Winter about the nutritional and gastronomic wonders of potatoes. It will inspire you to grow and eat more potatoes!
