Insurance crops that are there when you need them

You might think I wrote a typo for crop insurance, but no. There are some reliable vegetable crops that grow without much attention and quietly wait until needed. Chard is one of those. We sow chard in April, after the early spring rush. We plan for it to provide us with leafy greens in the summer, after the brassicas have bolted. We prepare a bed, unroll hay mulch over it, then make “nests” in the hay for planting. Nests are holes in the hay down to soil level, at each spot where we want to plant. After transplanting. we water and tuck the hay tight around the plants to keep the weeds at bay.

Some years there isn’t much demand for chard and we just leave it growing. If we need it, there it is with a generous supply of leaves. If we ignore it, nothing goes wrong. It’s worth having some crops like this in the garden, to help ensure there’s always something to eat.

This year we grew Malabar spinach and it played a similar role: hot weather leafy cooking greens. Malabar can be used when small for salads, or when larger for cooking. It wasn’t hugely popular in either role, but it was beautiful. To be fair, I don’t think we did the best by it. Because it was new, and because it had the word “spinach” in its name, some cooks served large leaves for salad. Alone. I don’t recommend that.

Another insurance crop for us is asparagus beans, also known as yard long beans. Once trellised, the plants need no attention, other than regular picking. If not picked, the pods grow puffy and useless, so this is not a crop to ignore for too long. Asparagus beans are related to cowpeas, and are more resistant to Mexican bean beetles than regular green beans are. They do need trellising, but once you’ve done that, the same plants will feed you all season. Very little seems to trouble them.

While we’re on the topic of crops that do need trellising, but can then produce all season, I’ll add in the West Indian gherkins. I found I did need to tuck these plants into the netting, so they weren’t work free. But the plants were disease-free and very productive. If you have trouble with regular pickling cucumbers, you might sow some of these as well, to be sure of being able to have something to pickle.

Another insurance crop is Tokyo bekana, or its cousin Maruba Santoh in late summer as a substitute for lettuce. It can be hard to germinate lettuce in hot weather, but these tender brassicas germinate under hot conditions and produce fast-growing very tender leaves with crunchy stems. Some people don’t know they’re not eating lettuce!

And for leafy cooking greens, senposai does well in spring and fall outdoors, and in our hoophouse in the

winter. It’s fast-growing, productive, disease-resistant, easy to cook and delicious to eat.  In spring it needs an early start in our climate, so that it has time to be productive before it bolts. In fall it’s cold-hardy down to 12F. This fall, though, we found its Achilles Heel – the senposai became an unplanned trap crop for Harlequin bugs! We did spend time every day for a while squashing the bugs on the senposai leaves, and we made a difference in the number of bugs. But we lost the senposai.

Well, I hope this has given you some thoughts about ordering seeds of some insurance crops for next year, when you plan your seed order.

Laura Lengnick, Carol Deppe, Growing for Market April issue

51qEC5xzBVLImage-contributor-s_avatarHere’s a new book I’m really looking forward to reading: Laura Lengnick’s Resilient Agriculture: Cultivating Food Systems for a Changing Climate. $19.95 from New Society Publishers.

Like many farmers, I’ve been struggling not to get despondent about erratic and extreme weather, especially in the past few years. I worry about how and if we are going to be able to adapt to continue producing good food despite extreme heat, cold, drought and deluge. I don’t want to slide into catastrophic thinking about plagues of new pests and diseases. Obviously we’ll need to make changes to how and when we plant and harvest – old-timey calendars don’t work any more.

I’m already there with the need for good record-keeping (to figure out what works best); eating and supplying local food (to reduce transportation fuel use and to get the freshest food); and doing my personal best not to make climate change worse. And I need help in understanding how to be more resilient and use the options I have. And it’s definitely time to start this!

I went to a workshop given by Laura Lengnick at the Carolina Farm Stewardship Conference in 2012: Managing a Changing Climate:A Farm Vulnerability Assessment and I was encouraged by her grasp of both the science and of farming. Her book is one of three being launched by New Society at the Mother Earth News Fair in Asheville, NC

Resilient Gardener_SmallResilience is a concept familiar to another author, Carol Deppe, whose new book The Tao of Vegetable Gardening will, sooner or later, get a review by me on this site. I enjoyed her earlier book, The Resilient Gardener: Food Production and Self-Reliance in Uncertain Times. That book focuses on staple crops for survival: potatoes, corn, dry beans, squash and eggs. Her new book includes other crops which make our lives richer and worth gardening for: tomatoes, peas, green beans, summer squash. I just read an interesting interview with Carol Deppe from Margaret Roach who blogs as A Way to Garden, and makes radio podcasts such as this interview.
GFM-April2015-cover-300pxAnd yet more reading! The April issue of Growing for Market is out. I’ve written the first of a pair of articles on hot weather greens. This one is about greens mostly cooked and eaten. next month my article will be about greens mostly eaten as salads. I know there is a lot of overlap, but I had to draw a line somewhere! This month’s article includes chard, Malabar spinach, New Zealand spinach, beet greens, Egyptian spinach, leaf amaranths, Aztec Spinach, Water Spinach, sweet potato leaves, squash leaves and shoots, crowder pea shoots and leaves and edible celosia. No need to go short of leafy greens, no matter how hot it gets!
Another article in this issue is about pesticide drift contamination, written by Joanna and Eric Reuter, whose fascinating blog I love to follow on their website Chert Hollow Farm. Their blog has a 3-part series of posts about their own experience of being contaminated by a neighbor. Their article tells their own story more briefly and also that of Terra Bella farm, an hour from them.
Jean-Martin Fortier has a great article on Six strategies to prevent weeds. We need them all! (Of course, we are already using some of them.) Raymond Cloyd from Kansas State University has written a timely article about the Spotted Wing Drosophila, a newly emerging pest of fruit, especially brambles. Gretel Adams, in her regular column on flower-growing, advises planting bulbs quickly and often. And Lynn Byczynski reports on what the ag census says about local food. Having the report read carefully and summarized for us is a great service.

What’s still standing after two nights below 0F?

Recently I reported on which crops were still alive after two nights at 14F (-10C) and What’s still alive after two nights at 4F?  We’ve now had the Polar Vortex, which brought us two nights at 4F, on 1/6 and 1/7. Then it got even colder.We got the Big Round 0F 1/22-1/23, then a few nights at 5F or 6F, and then the big insult: -4F on the night of 1/29-30.

What’s still standing?

The Tyee spinach under thick rowcover has sustained big damage, showing as patches of beige dead cells. It will recover. Meanwhile we can eat from the more-protected spinach in the coldframes and the hoophouse.

The Vates  kale without rowcover is still alive, but badly damaged. The big leaves are crunchy and brown round the edges, and some of the inner leaves are dead. I hope it will grow back, but we won’t be able to pick that for a while. The Beedy’s Camden kale looks worse – the big leaves have died and flopped over. Not sure if it will recover.

Many of our strawberry plants look dead – very disappointing!

Our hardneck garlic and Polish White softneck tops are killed back to about one inch up from the mulch. Equally hardy, it seems. 

We had the remains of a lettuce nursery bed, still holding surplus transplants from September sowings that we didn’t need for our greenhouse or hoophouse. After the 4F assault we still had life in the centers of the Winter Marvel, North Pole, Tango, Green Forest. Now only the Winter Marvel shows any signs of life. So that variety gets the prize for cold-tolerance here!

In the hoophouse, we covered all the beds with thick rowcover every night it looked like dropping below 10F inside. Almost everything survived – we only got some minor stem freezing on some turnips and Asian greens. We have been eating Pak Choy, Tokyo Bekana, Yukina Savoy, various turnips and their greens (Hakurei, White Egg, Oasis, Red Round), also plenty of lettuce leaves, radishes, scallions, and some spinach. We lost our second sowing of spinach in there to over watering and flooding, and we are really noticing the lack right now. We’re short on spinach. We have small amounts of mizuna, Ruby Streaks, Bright Lights chard, Bulls Blood beets to add to salad mixes, and Red Russian and White Russian kale growing slowly.

In January we have taken to sowing spinach, kale and collards in a hoophouse bed to transplant outdoors in early spring. We back this up with sowing some in flats if we don’t get good emergence for some reason. This year emergence is late. Is it just late, or is there a problem? We’re holding our breath for a few more days. . .

GFM_February2014_cover_300pxWe are not the only people tracking the effects of the unusually cold weather. The February Growing for Market magazine opens with an article by Ben Hartman “Testing the Limits of Cold Tolerance”. He farms in Goshen, Indiana, using two double-layer plastic greenhouses heated to 30F (yes. I said heated!) and two unheated. They planted kale, carrots, spinach, salad greens and arugula in their greenhouses for winter harvest. Their outdoor temperatures fell to -16F on 1/6 and 1/7. I imagine they’ve had worse since. They used mid-weight rowcover over their beds. Ben reports that baby greens and young spinach survived, as did their rosemary and their 3 fig trees (all farmers deserve some thrills!). They lost baby salad greens that had already been cut previously (all those cut edges didn’t do well). Crops in the outer beds were lost. The tips of full-grown kale leaves froze, but the plants survived.

In their unheated, single-skin plastic hoophouses, the soil froze down to 4″. They used two layers of mid-weight rowcover suspended over the crops. Despite this cold,  tiny salad greens less than 1″ tall survived. Spinach survived under just one layer of rowcover. The carrot tops froze and the roots may or may not be marketable. The (uncovered) fully mature kale looks dead. The mature salad with two layers of rowcover didn’t survive.

From this experience, Ben points out that salad greens and spinach less than 1″ tall are very cold-tolerant. Spinach and kale once larger, benefit from more protection than they got this time. Beware the outer beds!

My own article in this issue is about matching crop spacing with desired goals, such as maximum yield, optimum size, or convenience for cultivation.

Andrew Mefford has written some greenhouse tips for hoophouse growers, including tomato grafting, trellising. Chris Blanchard has written the second part of his piece on growing herbs – this is about harvest and maintenance. Erin Benzakain has undertaken a 59-variety trial of celosia.

 

What’s still alive after two nights at 4F?

Recently I reported on which crops were still alive after two nights at 14F (-10C) and several others in the teens. We’ve now had the Arctic Vortex, which in our part of central Virginia, meant two nights at 4F, last Monday 1/6 and Tuesday 1/7 nights. How did it go?

Before the Prelude to the Big Chill, when we got 9F, I harvested the odds and ends of small cabbages left in our main patch. Quite worthwhile, I got two 5-gallon buckets. Between the 9F and the 4F nights, I decided to gather the Deadon cabbage, which we grew with January harvests in mind. There was some freeze damage, so in future I’ll say that Deadon is good down to 10F, but not lower. I got two full net bags and two more buckets of small ones. I left one smaller and one larger cabbage as sacrificial victims in the cause of better information for next year. When we got 4F, the smaller one died and the larger survived.

I took another walk round the frozen garden after the Big Chill, to see what is still alive. We have Tyee spinach under rowcover, and Vates and Beedy’s Camden kale without rowcover. They are all still alive! There’s some freeze damage in spots on the spinach leaves, but plenty of good meals still to come!

Our hardneck garlic tops suffered some damage but didn’t get killed back to the mulch level. The Polish White softneck tops are considerably smaller and they too are still alive. They will grow back if they have died.

We had the remains of a lettuce nursery bed, still holding surplus transplants from September sowings that we didn’t need for our greenhouse or hoophouse. A good chance to see which ones are hardiest! Here’s the scoop:

Still alive in the centers – Winter Marvel, North Pole, Tango, Green Forest.                  No longer alive – Salad Bowl, Red Salad Bowl, Winter Wonder, Red Tinged Winter, Merlot, Red Sails, Outredgeous, Roman Emperor, Revolution.

At nearby Acorn Community, the home of Southern Exposure Seed Exchange, they had some young but mature heads of cabbage outdoors. The Late Flat Dutch, Early Flat Dutch and Chieftain Savoy all survived one night at 6F. (It’s usually two degrees warmer there than at Twin Oaks on winter nights).

Meanwhile I’m tracking the Blue Ridge kale grown by Clif Slade in his 43560 project at Randolph Farm, VSU. The Blue Ridge survived. It got down to 9F there. Not as cold as Louisa County! Blue Ridge is taller than the Vates we grow, and I’d like to try it here, if it can survive our winters. Otherwise not!

In the hoophouse, we covered all the beds with thick rowcover on Monday afternoon, and didn’t roll it up till Thursday, after the warmer weather returned. There was a tiny bit of freeze injury on some turnip greens that poked out the side of the rowcover, and some on some stems of Tokyo Bekana. I think the rowcover saved the crops! Also, a bad thing happened. it was very windy Monday night and the west window blew open. Argh! Of all the nights to have an open window. Memo: fix the latch to make it stronger.

I didn’t enjoy the really cold weather. I was anxious about the crops and the plumbing! But I can see two silver linings: I now have more information about cold-hardiness of various crops, and hopefully some pests will have died. Now we’re getting ready for another two cold nights, tomorrow and Wednesday.

When we placed our seed orders we gave up for this year on our quest for a reliable red cabbage of at least medium size and fairly speedy maturity (90 days or less). We’re having a red-cabbageless year. We’re still open to recommendations (OP or hybrid) – please leave a comment.

One of my ongoing topics of interest in the garden is how cold-tolerant various vegetables are. We’ve now had two nights at 14F (-10C) and several others in the teens. I took a walk round the frozen garden this morning to see what is still alive. We have Tyee spinach under rowcover, and Vates kale. The senposai is still alive, but some of the midribs have brown streaks. Sadly we don’t have any leeks this winter, as we lacked enough workers to tend them in late summer. We have a nice bed of Deadon cabbage, and I notice that some small heads of Melissa savoy that missed the bulk harvest are also alive. The Gunma cabbage stumps have some leaves and tiny heads still alive, but the Tendersweet are done in.

Our ongoing quest for a reliable red cabbage of at least medium size and fairly speedy maturity (90 days or less) yielded no success story this year. We grew Super Red 80 happily for many years, but then it stopped working for us – variable heads, slower maturity. If you have any recommendations (OP or hybrid) please leave a comment. We are working on our seed orders now, and this would be a great time to have some suggestions.

Back to today – our chard had all the leaves cut off in November, and seems to be dead. Some winters it hangs on later, if we leave some foliage to help it regenerate. We have also some years deliberately kept it alive for spring by using rowcover on it. We do that if we go into winter short of spinach beds.

The oats cover crop we sowed in August and early September look pretty much dead. All the broccoli looks dead. That’s as expected for the temperatures. Often we don’t get nights this cold till January – the cold came early this winter.

Our hardneck garlic tops look to be in good shape. The Polish White softneck tops are considerably smaller and look like they are suffering. They will grow back if they have died. Some of our Chandler strawberry plants look dead. Either that or they are extremely dormant! The deer were killing them off by eating the leaves. Too many deer!

The hoophouse is still bursting with great food. Plenty of salad greens: lettuce; various kinds of mizuna and ferny mustards like Ruby Streaks and Golden Frills and Bulls Blood beet leaves. And for salads or cooking we have spinach, chard, tatsoi, radishes, scallions, baby Hakurei turnips and their tasty greens, Red and White Russion kales, and more senposai. Soon we’ll start on the heading Asian greens: pak choy, Chinese cabbage, Tokyo bekana and Yukina Savoy. The first sowing of tatsoi (9/7) is starting to bolt, so we’re clearing that. The second sowing (11/15) needs thinning to an inch. The first round of baby lettuce mix (10/24) is ready for its second cut. In a few days we’ll make a second sowing of that. I love working in the hoophouse on sunny winter days. This afternoon I plan to complete the transplanting of an 11/9 sowing of spinach. We just love the sweet nuttiness of winter spinach!

Fall vegetable production – my presentation

Here’s the presentation I gave at the VSU  2013 Commercial Berry and Vegetable Filed Day at Randolph Farm, Petersburg on Thursday (6/27). Actually this slide show has some extra slides that I had to cut out to fit the time available. Registration for the field day had doubled compared to last year and reached 500. I don’t know how many were at the presentations, maybe 250. The other option was to continue the outdoor exploration of the research plots.

One section I would have loved to have seen, if I hadn’t been signing and selling books, and answering questions about VABF, was Clif Slade’s “43560” (Forty-three five sixty”) plot. He is aiming to demonstrate the viability of earning $43560 per year from one acre (43560 square feet) of intensive vegetable production. There are some You-Tubes about this project on http://www.youtube.com/user/VSUCoopExtension/videos

Around mid-July, check out http://www.vsuag.net/
for a video compiled by Michael Clark, combining my slideshow and me speaking.

Meanwhile, back at the farm, I’m sowing fall broccoli, cabbage and senposai, weeding sweet potatoes, sowing another succession of beans and one of edamame. More of our time is spent harvesting these days. Today we pulled a bag of beets, 2 buckets of beans, 2 buckets of lettuce (we’ll have a short gap until the next bed comes in), 6 buckets of broccoli, one bucket each of cukes, squash, zucchini, turnips and kohlrabi. Most of our crops are getting harvested every two days at this point (except lettuce, cukes and zukes). So no cabbage, kale, chard, scallions, blueberries or celery today.

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”.

A bed of various varieties of onions. Credit Kathryn Simmons

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.

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.

Transplant scallions, mini-onions, (shallots), lettuce #3.

Compost & till beds for late April planting: cucumbers #1, edamame #1, squash #1, peanuts, celery, parsnips, chard, cowpeas #1, (sesame). Can sow oats till 3/31 in beds not needed for 6 weeks.

Work on the Perennials in March: Really finish weeding, fertilizing and mulching them! Early in the month plant new blueberries, grapevines, raspberries, strawberries if not done in fall. Divide and replant rhubarb if needed. Water if needed, especially new beds. Set up irrigation and ropes where needed. Put up ropes for raspberries, mow between grapes. Maybe till up aisle in grapes and sow clovers & grass.

Irrigation Sprinklers: 3 sprinklers, 8 hours = 5000 galls, 3 drip-zones, 2 hours = 2160 galls, well output = 15 gpm, hydrant = 7.5 gpm.

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?).
