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 Organic Pumpkin and Winter Squash Marketing and Production

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.

Chert Hollow Farm on Organic certification, More Snow, Feed the Soil presentation.

Chert Hollow Farm's photos of their farm gate before and after.
Chert Hollow Farm’s photos of their farm gate before and after.

For some time I have been following the blog of Eric and Joanna Reuter of Chert Hollow Farm near Columbia, Missouri. I admire their commitment and creativity. Recently they have posted a three-part series on why they have decided to drop their USDA Organic certification. I found it a very thought-filled and coherent piece of writing and want more people to read it and ponder the points they make.

Dropping organic certification, part I talks about some of their concerns with the USDA Organic system as a whole, and how some of the Organic rules are increasingly at odds with their “beliefs and standards for sustainable and ethical food production.” Their work creating a diverse deeply-sustainable farm with minimal bought-in inputs isn’t easily reconciled with the USDA certification process. “Trying to use our own resources in a creatively sustainable way created an unusually-shaped peg that the organic system’s round holes don’t expect. And thus there’s a lot of subtle pressure on organic farms just to buy stuff rather than be more diversified and creative in their farming approach.” According to their Organic inspectors over the years, they have been star poster-child Organic farmers for five years, and their decision to leave Organic certification will be “a major loss to the organic certification community/process in this part of the country”.

In addition to the differing philosophy and practice between Joanna and Eric’s approach and the USDA, the costs are too high and the benefits too few.

Dropping organic certification, part II  goes into some of their specific issues with the certification. Concerns include costs, including the uncertainty of whether the government will continue the cost-share program; bureaucracy (why don’t chemical farmers have to track and report their inputs and applications??); and the degree of usefulness of USDA certification for direct marketing. As a CSA farm, Eric and Joanna are no longer competing for customers with self-proclaimed “organic” farmers at the market.

Dropping organic certification, part III looks at the benefits of dropping certification, while acknowledging what they learned by being part of the certified system, specifically the value of good record-keeping, good compost-making and careful sourcing of inputs. They credit being certified (and needing to check potential herbicide use on hay and straw they brought in for feed and mulch) with helping them avoid the “killer hay” incidents which are, sadly, all too common around the country. They write about what they are looking forward to, freed from the certification restrictions. They are increasing biological diversity on their farm, getting off mailing lists (!), and communicating more with customers and CSA members, know they’ll save time on certification paperwork. Finally, they discuss some of their regrets about no longer being part of “something bigger, a known collection of farms and consumers that stood for something different from the conventional agriculture model” they oppose. They will no longer have the support of USDA if they suffer from spray drift. They will no longer have an easy label to describe their farming practices to customers. Their hope is that more direct, personal communication with CSA members and the rest of the world will take over in addressing that need.

Meanwhile, here at Twin Oaks, we’ve had More Snow. Only about 3″, following rain. But it has brought a halt to our outdoor gardening pursuits for a while. Just before the snow we managed to get some disking done – the first of the year! We had got some raised beds tilled a few days earlier, so we managed to prepare those bed and sow beets, turnips, radishes and scallions, as well as the last of the snap peas. We haven’t transplanted anything except lettuce, scallions and spinach, because it has been so cold. We got beds ready for kale, cabbage, senposai and collards, before I realized the plants were too small to go outside! All our transplants have been growing slowly. We have postponed planting our tomatoes in the hoophouse because the weather is so unsettled (which is a mild way of saying scarily cold).

On Sunday 3/16, I co-taught Feeding Ourselves Sustainably Year Round with Cindy Conner and Ira Wallace. I blogged about this a couple of weeks ago. I spoke about Feeding the Soil. Here’s my slide show from that event:

During the Month:

Lettuce Factory: Sow heat-resistant lettuce outdoors, every 8 to 6 days, #10, 11, 12, 13, 14. Transplant 120/week (1/3 bed). #7, 8, 9, 10, 11 this month.

Deal with potato beetles with Spinosad [or Neem] once larvae are seen, if >50 adults/50 plants or >200 larvae/100 plants. Spinosad: Spray when bees not flying (early morning or late evening.) Shake well, 1-4 Tbsp/gall. Expect to need 1.5-2 hours and 9-10.5 galls. Clean and triple rinse the sprayer. Do not flush in creek or pond. Repeat if needed in 6-7 days – could spot spray where larvae are seen. Flame weed potatoes before 12” high, if needed.

Deal with asparagus beetles, if necessary. See notes under April.

Early May:

Continue cutting sweet potato slips until we have enough.

Transplant when hardened off: celery, celeriac, lettuce #7, main tomatoes (2’).

Set out drip tape & bioplastic mulch , transplant Romas (2’),  peppers (18” when soil 70°F, dogwood blooms dropping), hot peppers, and melons #1, sweet potatoes. 

Sow peanuts (120d), asparagus beans in bed w/ celery, okra, sunflowers. limas #1, cow peas #1 (68d)

Roll out driptape and bioplastic mulch for watermelons.

Cover Crops: Sorghum-Sudan, soy, buckwheat, or pearl millet as summer cover crops, now frost is past.

Mid-month:

Plant sweet potatoes, 16″ apart, with 4-4.5′ between ridges, 5’ at edges of patch. Install drip irrigation on ridges and plant at every other emitter. Ideal if soil temp is 65°F for four consecutive days before planting.  If weather dry, dip roots in mud slurry before planting.  Plant 2-3” deep, with at least 2 nodes in ground, and at least 2 leaves above ground.  If slips are long, plant horizontally to increase production.

Transplant lettuce #8, eggplant (2’ apart, single row in center of bed, spray off flea beetles with jet of water & cover immediately), watermelon, insectaries, (okra if not direct-sown – mulch later, when soil warm).

Set out drip tape and biodegradable mulch and transplant melons and watermelons at four weeks old max. Cover for 3 weeks. Move rowcover off broccoli (12 pieces) and strawberries (~8 pieces) Watermelon needs 12 pieces.

In greenhouse sow tomatoes #3, filler watermelons & Romas. Sow cukes & squash #2 if spring is late and cold, and direct-sowing not wise.

Sow beans #2 (5/14, 28 days after #1), edamame #2, carrots #6, sunflowers.

Till between rows of corn #1 & transplant in gaps and/or thin to 8”.

Weed onions 3 weeks before expected harvest date, and broccoli.

Garlic: Harvest garlic scapes, remove mulch from garlic, and weed.  Move mulch to weeded broccoli.

Check maturity of potato onions and garlic. Likely harvest order is fall potato onions 5/25-6/10, hardneck garlic 5/30-6/15, spring potato onions 6/3-6/18, bulb onions 6/11-6/30, softneck garlic 6/5-6/15.

#4 Spring Tractor Work mid-May – Disk areas for June potatoes, corn 3,4,5, & later succession plantings of beans, squash, cucumbers.

Late May:

Mow between no-till paste tomato rows before mulching with hay. Fill gaps, weed, tuck mulch.  Set up posts and string weave the tomatoes, using thick baler twine for lower 3 rows. Really try to keep up with weekly string-weaving.

String weave 1 row around peppers, using short stakes.

Clear empty coldframe and mulch with cardboard or plant something.

Till each corn twice, undersowing at 2nd tilling (30 days), when 12” high, with soy for #1-5, oats/soy for #6. Thin corn to 8”. Avoid cultivating corn after it’s knee-high—roots are shallow.

Sow corn #2, cowpeas #2; cukes #2 (picklers and slicers), summer squash & zukes #2 5/24 (or in greenhouse 5/14, transplant 6/7), watermelons #3, winter squash 5/26 (put woodash with seeds to deter squash vine borer). If squash sowing is late, don’t sow Tahitian butternut – slow.  Cover cucurbits (perhaps not winter squash) against cucumber beetles. Max. cuke beetle population is mid-May; keep susceptible plants well-covered until flowering.

Transplant lettuce #9, 10, 11; Roma paste tomato replacements for casualties, insectary flowers. Fill gaps in eggplant, peppers, melons, watermelons.

Store any seeds not needed until fall or next spring, in basement (radishes, onions, winter squash, watermelon).

Harvest fall planted Potato Onions in dry weather, after tops have fallen, (5/25-6/10, spring planted 6/3-18).  May not all be ready at once. Handle gently. Dry as clusters in barn on wooden racks for 1-2 months, using fans. Service fans or buy new as needed. Eat potato onions >2.5” without curing, unless yield is very low, in which case label & refrigerate, then plant in September. Weight after drying for 1 week is approximately twice the final weight. First sorting is late June. Use the Worksheet and Log Book

Harvest garlic when 6th leaf down is starting to brown on 50% of the crop (ie .5 green leaves, so that 5 skins cover cloves), or cut open horizontally- when air space is visible between. stem and cloves it’s time to harvest.  [Could replant small cloves immediately for garlic scallions.] Allow 15 mins/bucket harvesting and 15 mins/bucket for hanging in netting in barn,.

Till garlic area, sow soy & buckwheat to control weeds until fall carrot planting.

Plan fall and winter crops for raised beds.

Cover crops: can sow buckwheat, soy, millet, and sorghum-sudan during May.

Perennials: Put up blueberry netting before fruit sets. Weed & water & top up mulch. Mow grape & fall raspberry aisles. New grapevines: remove side branches and fruitlets. Weekly: visit grapes and log progress 4/20-5/30. If asparagus weeds are getting out of hand, mow down one or more rows to keep control.

All Month:

Lettuce Factory: In flats, (on greenhouse bench) sow lettuce #7, 8, 9 (romaines & small varieties to interplant with peanuts). Transplant 1/3 bed lettuce (120 plants)/week. Plant #4, 5, 6 this month.
Compost Needed for April: 6-9 tractor buckets for beds, 24-30 bkts to disk in.

Early April:

In greenhouse, sow lettuce #7;

Keep celery above 55°F, and celeriac above 45°F (don’t put in coldframe). 10 consecutive days <55°F for celery, <45°F for celeriac, causes bolting.

Spot lettuce, harden off in coldframe. Spot peppers, tomatoes, & eggplant. Protect new pepper seedlings from mice.  Keep tomatoes above 45°F at night, eggplant above 55°F.

Cut sweet potato slips at 6-12”, put in water.  Once a week, plant rooted slips in 4” flats.

Sow outdoors: carrots #5, beets (see March notes), parsnips with radishes #2, (in celery bed), sunflowers.

Weed and thin early crops. Side dress or foliar spray over-wintered spinach to boost production.

Take rowcover from turnips, senposai, cabbage #1, kohlrabi, little alliums, onions as needed for broccoli.

Transplant lettuce #4, main cabbage & broccoli under rowcover (12 pieces) within 6 weeks of sowing.

Till beds for mid-April. Compost beds for late April plantings.

Garlic bulbing is initiated on/after April 10 (13 hours daylight), and soil temperature above 60°F.

Mid April:

In greenhouse sow melons #1 in soil blocks or plug flats, replacement paste tomatoes, lettuce #8, and okra.

Sow beans #1 when lilac in full bloom, sunflowers. Sow edamame #1, corn#1, if warm, and soil >60F.

Till beds for late April (chard, cowpeas, peanuts). Compost beds for early May (okra, toms, melons, celeriac, lettuce 7,8,9, asparagus beans)

Hill up potatoes when 6” high. Cover half the vine. Repeat after 2 weeks. (Flameweed if too wet to hill.)

Take rowcover from kale, collards, early lettuce for raised bed tender crops.

Transplant broccoli #2, insectary flowers #1, bulb fennel, lettuce #5, cukes #1 w/nasturtiums, zukes #1; use spring hoops for cucurbits. Take rowcover from spinach to strawberries.

Install stakes every 8-10’ for peas and fava beans, and stringweave them to final height of that variety.

Weed garlic [or flameweed it early in the morning after a good rain. Direct flame at base of garlic plants]

Harvest lettuce as heads rather than leaves, from 15 April

#3 Spring Tractor Work (mid April) – Disk areas for sweet potatoes, winter squash, watermelons, (Romas and peppers if no-till cover crop insufficient). Bush-hog late food crop plots when rye heads up, to help clover or peas develop. Also clover patches, eg Green Fallow (All Year Cover Crops).

Late April:

in greenhouse sow lettuce #9; watermelons #1 & 2 in soil blocks or plug flats; calendula and various insectary flowers, filler corn & Romas.

Sow corn #1 (1/2-3/4” deep) in two phases, and peanuts if soil temperature is 65°F. Also cowpeas #1, and sesame.

Sow more leeks if needed in Little Alliums bed outdoors. If not, sow more mini-onions and scallions #3.

Transplant lettuce #6, leaf beet, chard, insectaries; finish transplanting gaps in the main broccoli & cabbage plot, plant Alyssum. Take rowcovers from broccoli & cabbage for new crops.

If mild, plant tomatoes. Harden off nightshades by restricting water.

Till beds for early May (okra, toms, melons, celeriac, lettuce 7/8/9, asparagus beans). Compost beds for mid-May (edamame, eggplant, limas).

Store spring and fall seeds (spinach, peas, beets) in the basement for the summer.

Foliar feed the potatoes, ideally the morning before hilling up, and every 2 weeks.

Roll out Driptape and Biotelos corn plastic mulch for peppers and Romas where no-till cover crop not used.

Cover crops: sow rye to wimp out. Sow buckwheat in any beds not needed for at least 5 weeks eg. leeks limas; add soy if bed not needed for 7 weeks. 

Haybine or bush-hog vetch & rye for no-till planting of Roma paste tomatoes, late in the month (or very early in May). (Mow strips; or till strips through the cover crop for the rows, with narrow-set tiller). Water the area before digging holes, if dry.

Perennials: Weed blueberries, asparagus, raspberries, strawberries, grapes as needed. Mow aisles. If asparagus weeds are getting out of hand, mow down one or more rows to keep control. Monitor asparagus beetles, spray spinosad when bees not flying, if >10 adults/100 crowns. Spinosad: Shake well, 1-4 Tbsp/gall (1fl.oz=2Tbsp=30ml.) Repeat in 6 days.

Cover strawberries if frost threatens – take rowcovers from spinach. (Pick flowers off any new spring  plantings.)

Visit grapes, log progress, remove flower buds from new vines. Note deaths and where replacement arms are needed.  Check and repair fruit drip irrigation, thin raspberries to 6/foot of row.

Harvest and weed: Asparagus, chard (hoophouse), collards, garlic scallions- pull at 8″, kale, leeks, lettuce, radishes, rhubarb, senposai, snap peas in hoophouse, spinach.

Transplant collards, kale, kohlrabi, senposai, lettuce #2, scallions #1, mini-onions. [spring-sown onion seedlings in clumps @12″, 1/2 to 1” deep].

Till raised beds before weeds seed, and sow oats (by 31st) if not needed for 6 weeks or more, (eggplants, cucumbers, squash, tomatoes, celery, later lettuce). Sow clovers until 3/15 for long-term cover; or winter rye to wimp out (it does not head up in warm weather).

Rhubarb

Divide and transplant rhubarb, if needed.

Sow carrots #3, turnips, beets. Presoak beets 1-2 hours, (not more), sow 1/2″ deep, tamp soil after covering.

#2 Spring Tractor Work  Mid-March –  Disk area for corn #1&2,

Late March: [side dress garlic & onions with compost]

In greenhouse: sow Roma tomatoes, lettuce #6, nasturtiums, chard and leaf beet in soil blocks or plug flats; squash #1 & cukes #1 in blocks or plug flats (not before 3/25). Spot eggplant. Sweet Potatoes: Cut slips at 6 to 12”, put in water.  Once a week, plant rooted slips in 4” flats.  Plant ginger in flats or crates.

Buy seed potatoes for June planting, and refrigerate them. Keep at 40-50°F in the dark, until 6/1.

Sow leeks & other little alliums in seed bed, update map; carrots #4 outdoors. Sow kohlrabi if transplants fail, thin to 6” later.

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?).

Here’s our list of tasks for October. If you garden in zone 6 or 7, your list might be similar. If you live in a very different climate zone, leave a comment about your list for October, and how many weeks different your area is from ours.

During the month

Weed and thin fall crops in raised beds, especially spinach and kale. Thin carrots to 3”, kale to 12”.

Lettuce Factory: Transplant sowing #37 to fill cold frames; #38, 39, 40, 41, 42 in Greenhouse beds (9″ spacing).

Frost Alert:

Watch the forecast and if frost is expected that night

When frost threatens, harvest all peppers exposed to the sky. Corona is one of our favorite orange peppers. Photo credit Kathryn Simmons

Harvest peppers facing the sky, tomatoes, cauliflowers, corn, cowpeas, limas, eggplant, melons, cukes, okra, winter squash, Blues cabbage (hardy to 25°F), if not already done.

Double hoop and cover: lettuce, celery (hardy to 16°F with row cover).

Spring hoop and cover: squash, cucumbers.

Cover celery to extend the harvest into mid-winter. We like Ventura.

Rowcover (no hoops): beans, Chinese cabbage, pak choy, Tokyo bekana, seedlings for hoophouse, collards  (hardy to 10°F, but cover keeps quality).

Cold frames:  Row cover between 32-28°F.  Add lids between 28-15°F.  Add quilts below 15°F.

Foliar spray greens with seaweed a few days before frost, to toughen them up.

Use overhead irrigation on peppers & tomatoes at night and some raised beds with tender crops.

Early Oct: Finish sowing spinach, kale by 7th for overwintering (last chance).

Transplant lettuce #37 to fill cold frames; #38, 39 in Greenhouse (9″ spacing).

Roll up drip tape from winter squash and sweet potatoes.

It’s time to roll up the drip tape from the watermelon, winter squash and sweet potato patches, in preparation for disking and sowing winter cover crops.

Move stored garlic from basement to fridge – store below 40°F or above 56°F, never 40-50°F.

Mid Oct: Till finished raised beds and sow wheat or rye before the end of the month.

Garlic Beds: Compost (5-6 tractor buckets), till and prepare beds.

Transplant lettuce #40, 41, 42, 43 in Greenhouse as needed, filling any gaps.

Get soil tests done, when soil is not too wet.

5th fall disking: By mid-month disk and sow cover crops where possible. Sow wheat or rye as covercrops – too late for oats or most clovers (Austrian Winter Peas Sept 15-Oct 24).  Could sow winter wheat mid-Sept to early Nov (good for small plots that are hard to reach with the tractor) and after sweet potatoes).

Harvest peanuts mid-late Oct after a light frost.  Wash, dry, cure 6 days in solar dryer facing east (don’t heat over 85°F), store.

Harvest sweet potatoes before soil temps go much below 55°F, or night air goes below 50°F: on 3 mild days – generally in the week that first frost usually occurs (10/7-14). Even a few hours exposed to temps below 50°F will cause chilling injury. (Frost on the leaves does not of itself damage the roots). Clip vines, dig carefully, set tubers in plant-clusters to dry on the soil. Select seed tubers (med-size tubers from high-yielding plants).  Save 100 Georgia Jet, 100 Beauregard, 20 each White and Jubilee. Cure in boxes with wood spacers and cover with newspaper, in basement with furnace going full time, for 7-10 days (85-90°F, 80-90% humidity).  Use fans. Splash water on floor. Curing is complete when skin is undamaged after rubbing two together. Restack boxes in storage cage.

Harvest white potatoes before the first frost (average Oct 14) if possible. Cure in root cellar at 60-75°F for 2 weeks, with good ventilation, then cool the cellar to lower temperatures: 50°F by 10/31, then 40°F for the winter.

Late Oct: Transplant lettuce #44, 45, 46 as filler in Greenhouse. Double hoop and cover spinach.

Planning: List successes & failures from labels. Prepare Garden Planning Schedule, Crop Review Sheets. Clean labels after info is recorded. Pray for a killing frost. File crop record info. Audit labor budget and plan endgame. Plan main garden layout. Hold Crop Review meeting.

Clear winter squash, tomatoes and peppers in order to sow cover crops, by 10/24 if possible. Sow rye alone or with crimson clover or winter peas. Crimson clover by 10/14; AWP, wheat by 11/8

6th fall disking: After the killing frost, or end of Oct if no frost: pull up tomato stakes and roll up drip tape, disk nightshades, melons, winter squash, sweet potato and white potato patches.

Check through veg in storage, squash once a week, white potatoes two weeks after harvest.

Perennials:Last mowing of clover in grapes in early Oct, not too short, and not too late in the year. Weed & mulch strawberry beds, and remove extra runners. Renovate if not already done. Start weeding, fertilizing and mulching the blueberries, raspberries, rhubarb and grapes.

Time to say goodbye to the rhubarb until April.

THE SECOND SPRING

Here’s our Garden Task List for September: 

During the month

Weed and thin carrots and brassicas (kale to 12”).

Lettuce Factory: Sow hardy lettuce every 2 days till 21st, (3 rows/planting) then every 3 days. Sow #34-46 this month. Transplant 120 every 3-5 days (1/3 bed) #27, 28, 29, 30, 31, 32, 33 for last outdoor planting (Dec harvest). Transplant  #34, 35, 36  9/24-9/30 for frames

Root cellar: air and cool to 60°F by mid-September

Collect seed from Roma tomatoes if necessary.

Screen compost and fill old greenhouse beds before October, for winter lettuce and spring seed compost.

Early Sept: Prepare and plant new strawberry beds if not done in late August, using rooted potted runners or plants carefully thinned from last year’s beds (see August for details).

Transplant collards and kale if necessary. Transplant lettuce #27, 28, 29, 30.

Retrieve spinach and onion seeds from the freezer. After acclimating spinach seeds, sprout 4oz/bed (1 cup/10,000 seeds) for spinach #1 in fridge for one week, then direct sow (if <68°F, and dead nettle has germinated). If still hot, sow (preferably pre-sprouted) spinach in Speedling flats in float tank. 9/20 is last sowing date for fall harvesting. [Could broadcast oats into spinach at planting time for weed control & cold weather protection.]

Sow if not done already: kale and collards by 9/15; turnips by 9/30; radishes, kohlrabi, daikon and other winter radish, miscellaneous fall greens, scallions.

Plant large potato onions this month or early in October, at 8” (wider if supply limited). Cover with ½-1” soil, mulch with hay.

2nd fall disking: Watermelon plot when 800 have been harvested. Roll up drip tape first, or move to new strawberries.

Mid Sept: 7-14 Sept is the best time to sow vetch & rye, 1:2, 2# of mix/1000 sq ft (75#/acre) on old spring broccoli patch; crimson clover and rye, 1:2, at 55#/acre.

Transplant lettuce #31, 32.

Sow 1st sowing of hoophouse seedlings (hoop and cover).

Bring 6 tractor buckets compost to hoophouse for fertilizing fall and winter crops.

Move stored onions from basement to fridge, after apples peak in mid-September, and space available.

3rd fall disking: corn #3, #4, #5. Part of corn #3 plot may be used for new strawberry beds.

Late Sept: Sow spinach #2 for spring harvesting (9/20-9/30), and 2nd sowing of hoophouse seedlings and cover.

Transplant kale for spring, filling gaps; lettuce #33, finishing up the last outdoor bed; [#34, 35 & 36 in cold frames?] Plant large potato onions (>2”) if not done earlier.

Move garlic from basement to fridge late September-late Oct as needed to make room for winter squash.

Weeding: this is a good catch up time on weeding in the raised beds.

4th fall disking and seeding: Sow cover crops wherever possible (in unused raised beds too). The last chance for oats is early Sept (9/15??). Can sow winter wheat (winter-killed in zone 4) or winter barley (dies in zone 6) if oat planting date missed. (Oats winter-kill in zone 8). Can sow hardy Austrian winter peas in late Sept at 8oz/100sq.ft. with rye. Can sow red clover this month.

Bush-hog late corn if undersown with oats and soy cover crop.

Perennials: New strawberry beds: Prepare and plant by mid-September if not done in late August. Weed strawberries. Could till up grass in grape alley & sow clover if not done in March. If clover sown earlier, let it seed.

Harvest and store winter squash: Acorn (pepo) types (stem still green, ground spot “earthy” or orange), store 1-4 months; Maximas: Cha Cha, Jarrahdale, Kabocha (stem 75% corky) store 3-5 months; Moschatas: Butternuts, Cheese (peanut colored skin, no mottling or streaks) store 4-8 months, or more. Leave on live vines as long as possible, avoiding frost on fruits. Cut leaving long stem using pruners; handle gently.

September Harvests: Asian melons, asparagus beans, beans, beets and beet greens, broccoli, cabbage, cantaloupes, carrots, cauliflower, celery, chard, Chinese cabbage, corn, cow peas, cukes, edamame, eggplant, horseradish,leeks, lettuce, limas, maruba santoh, okra, pak choy, peppers, hot peppers,radishes, Romas, scallions, senposai, summer squash, Tokyo bekana, tomatoes, turnips, watermelons, winter squash, yukina savoy, zucchini.  It is possible to lightly harvest rhubarb during September, if wanted.
