Quick crops to fill hoophouse space Oct 1-Nov 29

This fall we had unused space in a bed where we planted Oct 1 radishes and Tokyo bekana (transplanted), Oct 2 brassica salad mix and Chinese cabbage and Oct 3 pak choy. On Oct 4 we had planted only 44ft, half the bed.

On Oct 10 we made a tiny 1.5ft sowing of brassica gap-filler plants. Oct 20 and 23 we did a bit more planting: scallions, radishes and more filler greens and lettuces (12.5ft), leaving 30ft still empty after Oct 23.

The next plantings were more fillers on Nov 9 (5ft), tatsoi on Nov 15 (7ft), radishes on Nov 29 (2ft), total 14ft more, leaving 16ft still empty. Then came lettuce mix on Dec 7 (12ft), leaving 4ft for brassica salad mix #2 on 12/18. Weeks of bare soil – ugh!

Then we start clearing the first round of crops (clearing radish #2 for Dec 8 brassica salad mix #1.5, 2ft) and Dec 18, clearing 4ft of radish #2.5 south side only,  for more brassica salad mix #2, Dec 23 (clearing brassica salad mix #1 for radish #5, 4ft).

If we have a similar crop arrangement next winter, or small empty patches in various beds, what can we plant in space that is still empty after Oct 10, and especially the spaces that don’t get planted until mid-November onwards? We could try different crops, for the various crops that follow.

Qualities of possible crops:

  • Ready to eat 19-83 days from sowing or transplanting. Most spaces 30-60 days.
  • Cold weather crops, not warm weather crops
  • Something we’ll want to eat then, that we don’t already have lots of.
  • Or something that could be processed for later (we generally have enough greens in winter)
  • Maybe not spinach, as it’s a challenge with pests in the fall.
  • (Preferably not brassicas as we grow so many and stretch the crop rotation.)

Ready to eat 21-60 days from sowing

Tips (based on Johnny’s Key Growing Info):

  • Grow when the weather is warm 65°F (18°C). Hmmm?
  • Soak seeds for 8 hours (do not re-use water).
  • Sow seeds thickly and lightly press seeds into soil. Shade?
  • Keep moist.
  • Shoots should be at an edible size (3–6″) within 7–21 days.
  • HARVEST: Using a sharp harvest knife or scissors, cut the shoots just above the soil line. Place in plastic bags or sealed containers and refrigerate. [Could use up leftover pea seed that won’t be any good next spring]

Eat-All Greens (35 days from sowing). Invented by Carol Deppe, as a method of growing cooking greens quickly with little work, direct sown and cut at 12″ tall, leaving the tough-stemmed lower 3”, perhaps for a second cut, or to return to the soil. She recommends 7 greens in particular: Green Wave mustard, Shunkyo and Sensai radishes, Groninger Blue collard-kale, Burgundy amaranth, Tokyo bekana, and Red Aztec huazontle. We tried this outdoors one fall, and I wrote 3 blog posts about it. The crops that did best for us were fava beans, peas, radish greens, Maruba Santoh and Tokyo bekana, frills, turnip greens, Siberian kales. The ones that didn’t work outdoors were kohlrabi, beets, and chard. (We sowed old seeds we had, didn’t buy the recommended ones)

  • Earlier turnips (45d)
  • Beets and their greens (easier than spinach and a double crop) (50-60d)

Ready to eat 30-60 d from transplanting

(in order of earliness):

 

Fedco’s Red Dragon Chinese cabbage 60d to harvest

  • Earlier Senposai – but we have outdoor senposai to harvest in Oct and Nov (40d from emergence after sowing; 20 days from transplant)
  • Komatsuna (45 days from emergence after sowing; 25 days from transplant)
  • Kohlrabi (45-60d from 25-40d from transplants)
  • Earlier Napa cabbage (Blues) (52 days from emergence after sowing; 32 days from transplant).
  • Fedco Red Dragon Chinese cabbage (60 days from emergence after sowing; 40 days from transplant)
  • Small early cabbage like Farao, Golden Acre and EJW are all about 62 days from emergence after sowing; 42 days from transplant
  • Broccoli Tendergreen is 67 days from emergence after sowing; 47 days from transplant

Ready to eat 90 days from planting

  • Garlic scallions. We normally plant these in early November and eat in early March (120 days). But if we plant them earlier, in a warmer place, they’ll be ready sooner. Normally you don’t want to plant garlic until the soil cools to 50F (10C), because it would grow too fast and not survive the winter. But if it’s just the scallions you want, the rules change. . .

Clif Slade, who farms in a slightly warmer climate zone in Surry, Virginia, tells me they plant garlic for scallions outdoors in every month except August, and in the hoophouse until January (from September?). December plantings are ready indoors in March, outdoors in April. He generally reckons 90 days from planting to harvest, in warm conditions. Any garlic is suitable. Hardneck, softneck, small cloves, large cloves, whole small bulbs. Best return is on small garlic, although bulbs with lots of small cloves can be tiresome to pull apart!

When to sow crops to transplant?

And how would this fit into our schedule?

  • We’d need to sow 3-4 weeks before a transplant date of Oct 1, thst’s Sept 1-7.
  • We could sow Sept 15 with our first round of hoophouse transplants. Transplant Oct 7-15 approx
  • Start the hoophouse nursery bed two weeks earlier?
  • Or sow in the lettuce nursery seedbed which is already in use in early September?

It looks like we might have 30ft total available for fast crops. Here’s what fits:

  1. Oct 1-Oct 20, 12.5ft. 19 days. Pea shoots, small transplanted senposai.
  2. Oct 1-Nov 9, 5ft. 39 days. Eat-All Greens, transplanted senposai, komatsuna, or kohlrabi, or pea shoots. Maybe garlic scallions.
  3. Oct 1-Nov 15, 7 ft. 45 days. Turnips, transplanted Blues, Red Dragon, small cabbages, or as in B.
  4. Oct 1-Nov 29, 2ft. 59 days. Beets and beet greens, or transplanted Tendergreen broccoli, or as in C.
  5. Oct 1-Dec 7, 12 ft. 67 days. Any of the above
  6. Oct 1-Dec 23, 4 ft. 83 days. Any of the above.

Caution about slow growth

Growing slows down in November and December, so maybe we should be cautious the first time and add 10-14 days to the days to maturity??

Radishes

Some years ago I figured out a sequence of sowing dates that would give us an even radish supply, without gaps or gluts. For various reasons, we drifted away from those dates, and I’d like to get back to them again. Sept 6 is the earliest we can sow in the hoophouse. Jan 25 is the latest date that will give us a worthwhile harvest, starting Jan 27. Skipping that last one would be OK.

#1 #2 #3 #4 #5 #6
Suggested Sept 6 Sept 30 Oct 27 Nov 23 Dec 20 Jan 25
Sowing interval 24 days 27 days 27 days 27 days 36 days
Harvest start Oct 1 Nov 4 Dec 8 Jan 11 Feb 14 Mar 20

Preparing to order seeds

Preparing to order seeds: 6 steps + 3 extra tips

Leeks grow slowly. Sow in March to have seedlings this size in May. Order seed soon! Photo Pam Dawling

There are lots of new gardeners now, as a result of the pandemic causing people to stay at home, cook more and want more food security without going inside grocery stores. Maybe last year you bought packets of seeds in a hurry, either online or off a rack in as store. Maybe you hope your garden will go more smoothly this year and I’m here with this blog post to help you.

Or perhaps you are a new professional grower, seeking to improve your game. Or an established one, looking to hang in there by farming smarter in these hard times.

‘Tis the season for garden planning. Inventory your seeds left from last year, peruse the catalogs and prepare your seed orders. The earlier you get them in, the more likely you are to get the varieties you want, before anything is sold out. Be prepared, note your second choice, and fend off disappointment!

I have a course on garden planning for home gardeners, on the Mother Earth Fair Online. It consists of eight half-hour workshops, covering all aspects of garden planning from clarifying your goals, choosing crops, making maps of what will go where, planning when you want to harvest, determining how long your rows will be and how much seed to order, deciding when to plant and scheduling everything to make the year go smoothly. There are also workshops on ways to pack more in, and how to be prepared for things that don’t go according to plan!

Commercial growers and energetic home growers will also be interested in the information on garden planning in my book Sustainable Market Farming.

I have a couple of slideshows on SlideShare.net,

 First, a basic 6 steps of garden planning

  1. See How to Decide Which Crops to Grow.

Think about what you grew last year, and whether you want the same again. Think about what you wished you’d grown. Every year we try to introduce a new crop or two, on a small scale, to see if we can add it to our “portfolio.” Some-times we can successfully grow a crop that is said not to thrive in our climate. (Brussels sprouts really don’t). We like to find the varieties of each crop that do best for our conditions. Later we check how the new varieties do compared with our old varieties. We use heirloom varieties if they do well, hybrids if they are what works best for us. We don’t use treated seeds or GMOs, because of the wide damage we believe they do. For ideas of what you might grow, see our Twin Oaks Harvest Calendar by Crop.

2. Are any of your leftover seeds OK to keep?

See making an inventory, and Ordering seeds! Seed Viability Many seed catalogs include information about seed longevity, and so does Nancy Bubel in The Seed Starters Handbook. Frank Tozer in The Organic Gardeners Handbook has a table including minimum, average, and maximum.

A simplified version of how long to keep seeds is as follows:

  • Year of purchase only: Parsnips, Parsley, Salsify, and the rarer Sea Kale, Scorzonera
  • 2 years: Corn, Beans and Peas of all kinds, Chives, Dandelion, Martynia, Okra, Onions,
  • 3 years: Asparagus, Carrots, Leeks, Rutabagas, Turnips,
  • 4 years: Artichokes, Basil, Cardoons, Chard, Peppers, Pumpkins, Spinach, Squash, and Watermelons,
  • 5 years: Beets, most Brassicas, Celery, Celeriac, Chicory, Cucumbers, Eggplant, Endive, Lettuce, Muskmelons, Tomatoes,

Rather than deteriorating with age, some very fresh seed has a dormancy that needs to be overcome by chilling (lettuce).

The fuller story is that storage conditions make a big difference. Keep seed cool, dark, dry in airtight, mouseproof containers.

  1. How Much of What to Grow?

Make a rough map of your garden space and see what will fit. Remember you can plant a later crop in the same space after an earlier one finishes. See below for more info on quantities of potatoes and garlic, two staples.

  • How Much Garlic to Plant

A yield ratio of 1:6 or 7 seems typical, and makes complete sense when you consider you are planting one clove to get a bulb of 6–7 cloves. Divide the amount you intend to produce by six to figure out how much to plant. For large areas 750–1,000 lbs/ac (842–1,122 kg/ha) are needed for plantings in double rows, 3″–4″ in-row (7.5–10 cm), beds 39″ (1 m) apart. For single rows, 8 lbs (3.6 kg) of hardneck or 4 lbs (1.8 kg) of softneck plants about 100′ (30 m). In the US, one person eats 3–9 lbs (1.4–4.2 kg) per year.

  1. How Much Seed to Order?

Hopefully you kept some kind of record on whether the amount you bought last year was enough. When we figure out how much seed to order we add in some extra for some things – crops that can be difficult to germinate, or we really don’t want to cut too close. We add 20 percent extra for most crops, but only 5 percent for kale, 10 percent for onions and collards and 30 percent for melons. These numbers are based on our experience – yours might be different. We also know which seed we can buy in bulk and use over several years. This gives us an additional security against poor germination, or plagues of grasshoppers or caterpillars. For me, a big bag of broccoli seed for each of our main varieties gives some kind of warm glow of horticultural security! Buying too much either leads to wasting money (if we throw it away) or wasting time and money (if we sow old seed that doesn’t come up well, then have a crop failure).

If you use spreadsheets, see my post Cooking Greens in December Special Topic: Ordering Seeds.

Here’s a helpful table of 1000 Seed Weight for 13 crops. Another of the challenges with seed ordering is converting between grams, ounces and seed counts – have your calculator at the ready, or easier still, just type “Convert ½ oz to grams”into your search engine.

 

  1. Choosing varieties.

See How to read seed catalogs for tips on getting what you really want by paying attention to what’s in the small print and what isn’t mentioned. We carefully look for varieties that offer the flavor, productivity and disease resistance we need. The catalogs are starting to appear in my mail box. The early bird catches the preferred varieties! The main companies we order from are Fedco Seeds, Johnny’s Selected Seeds and of course, Southern Exposure Seed Exchange. We like SESE for regionally adapted varieties, Fedco for great prices on bulk sizes, and Johnny’s for some varieties we really like that aren’t available from the other two.

 

  1. Formatting and placing seed orders

We grow lots of different crops, so we make a spreadsheet, and include columns for the name of the supplier we buy each variety from (we just use the initial), the item number in the catalog, the packet size and the price. (Be careful though, if you carry this information over from year to year – prices change.) Once we have composed our total seed order, we sort the orders by the name of the supplier. Then we can calculate the total price for each supplier. This also gives us the opportunity to look at price breaks for large orders and move an item from one supplier to another, if that makes sense. At this point we usually make a cup of tea and reward ourselves with an “impulse buy” or two, if that doesn’t push us up into a higher shipping cost bracket or blow the budget. We place our orders online these days, nice and early, to increase the chances of getting exactly what we want.

Here are a few more thoughts on crops to consider:

  1. Insurance crops that are there when you need them

For an overall sense of success, grow some “Insurance Crops”. These are 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.

One 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 southern peas (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!

Senposai is a cooking green that 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.  Its Achilles Heel is that it can really attract 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.

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.

  1. VEGETABLE CROPS THAT OFFER FAST RETURNS

Because things can go wrong in agriculture, (we are, after all, not in control of the universe!) I like to have on hand seeds for fast-growing crops that can fill unexpected gaps.

  1. Eat-All Greens

Carol Deppe, in her delightful book The Tao of Vegetable Gardening introduces us to the concept of Eat-All Greens. Carol grows these by broadcasting seed of one of her carefully chosen greens crops in a small patch. When it reaches 12″ tall, she cuts the top 9″ off for cooking, leaving the tough-stemmed lower part, perhaps for a second cut, or to return to the soil. I wanted to try this idea in Virginia, where the climate is fairly different from the Pacific Northwest where Carol lives. I decided fall was a promising time of year to try this scheme, as our spring planted greens only have a short season before they bolt. And summer is too hot, winter too cold. . . We sowed in mid-September.

These can also be insurance crops, in that, if you don’t need them, you can cut and compost them, to let fresh leaves grow. I wrote three posts on Eat-All Greens, because they were such fun and so productive

Fast Growing Vegetables

Maybe part of your response to Covid-19 is to grow more of your own food, and you are wondering what can bring fastest results. Or maybe you just want to leap into spring and have early harvests. Either way, here is information on some vegetable crops that offer fast returns; ways to get crops to grow faster; ways to get more crops from a small space and some sources for more information.

Vegetable Crops That Offer Fast Returns

In my blog post If Spring is Too Wet in March 2019, I included a paragraph on fast crops.

  • Ready in 30–35 days from sowing are baby kale, mustard greens, collards, radishes, spinach, chard, salad greens (lettuce, endives, chicories) arugula, and winter purslane. Beet greens from thinnings can be cooked and eaten like spinach.
  • Many Asian greens are ready in 40 days or less: Chinese Napa cabbage, Komatsuna, Maruba Santoh, mizuna, pak choy, Senposai, tatsoi, Tokyo Bekana and Yukina Savoy). See my Asian Greens of the Month category of posts. There’s a huge range of attractive varieties, they’re better able to germinate in hot weather than lettuce, and faster growing than lettuce. Most reach baby salad size in 21 days, full size in 40 days. Transplant 4-5 weeks after spring sowing, or direct sow. Nutritious as well as tasty. Flavors vary from mild to peppery; colors cover the spectrum: chartreuse, bright green, dark green and purple. A diversity of crops without a diversity of growing methods! Grow when you normally grow kale. Be aware that Asian greens sown in spring will bolt as soon as the weather heats up, so be ready to harvest a lot at once (if you planted a lot, that is!) You can make Kim Chee.

  • Tatsoi and our August sown catch crop of Tokyo bekana.
    Photo Pam Dawling
  • One summer we sowed Tokyo Bekana as a lettuce substitute. 20 days to baby size, 45 days to a (large) full size. We have also grown this at other times of year, when faced with an empty space we hadn’t planned for.
  • Mizuna and other frilly mustards are very easy to grow, and tolerate cold wet soil to 25°F (-4°C). In addition, they are fairly heat tolerant (well, warm tolerant). Use for baby salads after only 21 days or thin to 8″–12″ (20–30 cm) apart, to grow to maturity in 40 days. Mild flavored ferny leaves add loft in salad mixes and regrow vigorously after cutting.
  • Also ready in 30–35 days are spinach, chard, salad greens (lettuce, endives, chicories) and winter purslane.
  • Ready in 35–45 days are baby carrots (thinnings or the whole row), turnip greens (more thinnings!) endive, corn salad, land cress, sorrel, parsley and chervil. Some of the faster smaller turnip roots can also be ready in 45 days or less.
  • Ready in 60 days are beets, dwarf snap peas, broccoli, collards, kohlrabi, turnips and small fast cabbages (Farao or Early Jersey Wakefield).
  • Also ready in 50-60 days once we are past frosts: zucchini, yellow squash, bush beans, small cucumbers can grow fast.
  • Garlic scallions can be grown over-winter, but will grow quickly in spring. Plant scrappy little garlic cloves you don’t want to cook with in close furrows and wait till the leaves are 7” (18 cm) tall before digging up the plant and preparing like onion scallions (spring onions). Can be eaten raw, but more often cooked. You can also plant whole bulbs without separating the cloves. This is a good use for extra bulbs that are already sprouting in storage.

  • Try Eat-All Greens, an idea form Carol Deppe. Patches of carefully chosen cooking greens are sown in a small patch. When it reaches 12″ tall, Carol cuts the top 9″ (23 cm) off for cooking, leaving the tough-stemmed lower part, perhaps for a second cut, or to return to the soil.

  • Spinach is good for salad or cooking uses. Be aware that the fastest biggest spinach may not last long once it warms up! We have found Acadia and Reflect have good bolt-resistance from outdoor spring sowings.

Fast Varieties of Lettuce and Greens

  • Grow the right lettuce variety for the conditions. Ones that do well in early spring are often useless here after the end of March, or even mid-February. I like to sow 4 varieties each time (for the attractive harvests, and to reduce the risks if one variety bolts or suffers disease): at least one red and one romaine. We have 5 lettuce seasons, with different varieties:
    • Early Spring (Jan – Mar), 6 sowings
    • Spring (April – May 15), 5 sowings
    • Summer (May 15 – Aug 15), 17 sowings (lots of seed!)
    • Fall (Aug 15 – Sept 7), 9 sowings
    • Winter Sept 8 – 27, 9 sowings
  • Baby lettuce mix can be ready in as little as 21 days from mid-spring to mid-fall. A direct-sown cut-and-come-again crop, the plants regrow and can be harvested more than once in cool seasons. Weed and thin to 1″ (2.5 cm). When 3″–4″ (7.5–10 cm) tall, cut 1” (2.5 cm) above the soil. Gather a small handful in one hand and cut with using large scissors. Immediately after harvesting, weed the just-cut area so the next cut won’t include weeds
  • Leaf lettuce can be harvested by the leaf much sooner than waiting for a whole head of lettuce.
  • Small-leaf lettuces (aka Eazyleaf, One-Cut, Multi-Cut, Multileaf): Johnny’s Salanovas, Osborne’s and High Mowing’s Eazyleaf; Tango, Oscarde, and Panisse (older varieties) too. Full-size plants can be harvested as a head, or harvested with a single cut, providing a collection of bite-sized leaves. Or just one side (or the outer leaves) of the plant can be cut and the plant will regrow for future harvests. Growing multileaf heads takes 55 days, compared to 30 days for baby lettuce.

  • Other greens can be sown in close rows for harvesting as salad crops at a height of 3”-4” (7-10 cm). These are called mustard mixes or brassica salad mixes.
  • Many cooking greens can be used as salad crops while plants are small, as you thin the rows of direct-sown crops.

Ways to Get Crops to Grow Faster

  • Sow when the conditions are right. Soil temperature is important. I have a table of soil temperatures in Year-Round Hoophouse on page 208. Vegetable Seed Germination: Optimum soil temperatures for germination and days to emergence, where known.
  • Grow transplants. By starting your plants in a place with close-to-ideal temperatures, rather than direct-seeding when it’s still a bit too chilly outside, you’ll get bigger plants sooner. You’ll also buy time to prepare the soil where you are going to plant out.
  • Find warm sheltered micro-climates, in front of a south-facing wall for example.
  • Make your own warm sheltered micro-climates with rowcover or low tunnels.
  • Take advantage of plastic mulch to warm the soil, for crops that like warmth. Regular black plastic mulch will need to be removed at the end of the growing season, but biodegradable mulch does not. However, if you are taking over part of your yard near your house, I should tell you that you will see shreds of the bioplastic next year. See Setting out biodegradable plastic mulch by hand

  • Consider landscape fabric with planting holes burned in, as a reusable alternative to throw-away or biodegradable mulch.
  • Use mixes for salads: Our general salad mix harvesting approach is to mix colors, textures and crop families. I like to balance lettuce of different kinds with chenopods (spinach, baby chard, Bull’s Blood beet leaves) and brassicas (brassica salad mix, baby tatsoi, thinnings of direct-sown brassicas, chopped young leaves of Tokyo bekana, Maruba Santoh or other Asian greens, mizuna, other ferny mustards such as Ruby Streaks, Golden Frills and Scarlet Frills). See Making salad mix
  • Microgreens: See Andrew Mefferd The Greenhouse and Hoophouse Grower’s Handbook.
  • When the weather warms up, consider using shadecloth for heat-sensitive plants, particularly lettuce, but any of the cool weather greens you still have by then.
  • In warm weather, greens and lettuces inside a tipi of pole beans will benefit from the shade.

Ways to Get More Crops from a Small Space

  • With transplants, you can fit more crops into each bed throughout the season, because each crop is occupying the bed for less time than if direct-sown.
  • Transplanting can help you grow more successions of summer crops, as each one needs less time in the garden or field.
  • Grow a vertical crop on a trellis and something short in the space below it. You can even use the same trellis twice, growing tomatoes after peas, for instance.

  • Relay Planting is a method of growing short crops alongside taller ones. We have often sown peas down the center of a bed of overwintered spinach. As the peas grow tall, we trellis them, and continue harvesting the spinach. When the spinach bolts, we pull it up. This overlap of bed use lets us get more crops from a bed in less time than if we sowed the crops one after another. We have also sowed peanuts down the middle of a bed of lettuce on the same date we transplant the lettuce. We make sure to use vertical romaine lettuces rather than sprawly bibbs or leaf lettuces. We have transplanted okra down the middle of a bed of early cabbage. This does involve breaking off outer leaves of the cabbage if they are about to smother the okra.
  • Sow some slower-maturing crops the same time as you sow the fast ones, so you have food later as well as sooner! Carrots, turnips, cabbages, broccoli, collards, kohlrabi,
  • Sow some multiple-harvest crops to save work later. Greens that are harvested by the leaf, rather than the head, offer good value.

For each bed, determine how many months that food crop occupies that bed and so assess the productivity value of one crop compared with another. Short season crops grow to harvest size in 30-60 days, allowing series of crops to be grown in the space, and feeding people quickly. 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!
  • Curtis Stone, in The Urban Farmer, distinguishes between Quick Crops (maturing in 60 days or less) and Steady Crops (slower maturing, perhaps harvested continuously over a period of time). He has designed a Crop Value Rating system based on 5 characteristics. To use this assessment, you look at each characteristic and decide if the particular crop gets a point for that characteristic or not. Then look for the crops with the highest number of points. Spinach gets all 5 points; cherry tomatoes only 3. The smaller your farm, the higher the crops need to score to get chosen. His 5 are:
  1. Shorter days to maturity (fast crops = chance to plant more; give a point for 60 days or less)
  2. High yield per linear foot (best value from the space; a point for1/2 pound/linear foot or more)
  3. Higher price per pound (other factors being equal, higher price = more income; a point for $4 or more per pound)
  4. Long harvest period (= more sales; point for a 4 month minimum)
  5. Popularity (high demand, low market saturation)

Cooking Greens to Harvest in Central Virginia in October

Beet greens, broccoli, cauliflower, cabbage, chard, Chinese cabbage, collards, kale,  komatsuna, Maruba Santoh, pak choy, senposai, spinach, tatsoi, Tokyo Bekana turnip greens and Yukina savoy can be available here all month (and perhaps longer, depending on the temperature). OP Yukina Savoy seems more cold-hardy  and bolt-resistant than the hybrid Koji.

The new outdoor greens this month are tatsoi, kale, spinach, collards, and mizuna (if we have that outdoors).

Eat-All Greens harvests can start, if you sowed some last month. When we sowed some on September 16, we got two harvests in October and several in November.

From the hoophouse we start to harvest spinach, tatsoi, and leaves of Tokyo bekana.

Cooking Greens to Sow in Central Virginia in October

This month we finish sowing spinach and kale for overwintering outdoors (10/30 is our last chance). No more outdoor sowings until spring!

“Filler Greens”

Filler greens: short rows of Tokyo bekana, Yukina Savoy and senposai used to fill gaps in the winter hoophouse.

On October 10, we sow Brassica fillers #1. These are short rows of senposai, Tokyo bekana, Yukina Savoy, Maruba Santoh,  to use to fill gaps later during the winter as soon as they occur. We simply dig them up, replant where needed and water well. Alternatively you could keep some plug flats of these plants handy. Bare-root transplanting is much easier than many fear.

During December we use the “Filler” greens plants to replace casualties and harvested heads of Tokyo bekana, Maruba Santoh, Chinese cabbage, Pak choy, Yukina Savoy and tatsoi daily. We stop filling gaps in these early harvest crops on December 25, as they will bolt in the hoophouse conditions in January at the latest.

We continue to fill gaps elsewhere with senposai until January 25. Asian greens don’t make good growth before bolting if transplanted after January 25. From January 25 to February 20 we fill all gaps everywhere with spinach transplants

Hoophouse Bed preparation and Planting

In the hoophouse we have a lot of bed preparation (all the beds except the Early Bed which we plant in September), as well as transplanting and sowing.

On October 14, we sow turnips #1: Red Round (1 row on North), Hakurei (2 rows South). Oasis, White Egg.

On October 20, we sow Filler Greens #2.

By October 23, we clear and prepare two more beds and sow spinach #2; tatsoi #2, turnips #2, chard #2 and perhaps Frills (Frilly Mustards) #1.5.

Brassica (Mustard) Salad Mix

Interesting mustard mixes are sold for salad mixes. We often mix our own Brassica Salad Mix from leftover random brassica seeds. For a single cut, almost all brassicas are suitable – just avoid turnips and radishes with prickly leaves! We sow between October 2 and November 14 for harvests during the winter, and from December 4 to February 12 for March and early April harvests.

We could, but so far we haven’t, sow Eat-All Greens in hoophouse in October.

Catch crops

Useful if a crop fails, or you have an empty space. Don’t delay, as rates of growth slow down as the temperatures and daylight decrease. Don’t expect much from sowings during the Persephone Days (less than 10 hours daylight).

This year we grew an early catch crop of Tokyo bekana when we realized we had space that wouldn’t be needed till mid-October (for turnips). We direct sowed it August 28, weeded and thinned to 1” (2.5 cm) on September 5; weeded and thinned to 3” (7.5 cm) on September 16, using the small plants for salad. We need to clear this crop by the middle of October to sow the turnips, and the Tokyo bekana has got to a fine size.

  • Ready in 30–35 days in fall, longer in winter: brassica salad mixes, spinach, chard, salad greens (lettuce, endives, chicories), winter purslane., kale, arugula, radishes (the fast small ones and the larger winter ones), many Asian greens: Komatsuna, Maruba Santoh, mizuna, frilly mustards, Senposai, tatsoi, Tokyo Bekana and Yukina Savoy.
  • Ready in 35–45 days in fall: corn salad, land cress, sorrel, parsley and chervil.
  • Ready in 60 days in fall: beets, collards, kohlrabi, turnips

Cooking Greens to Transplant in Central Virginia in October

September sown White Russian kale (transplanted in October).

In our hoophouse in early October, we transplant Tokyo Bekana, Chinese cabbage, Pak choy, Yukina savoy #1,  using plants which we sowed outside under insect netting.

By October 13, we transplant chard #1, Frills #1, and Red and White Russian kales, from our outdoor nursery seedbed.

By October 21, we clear and prepare another bed and transplant 1/2 bed kale, plus Yukina Savoy, and frilly mustards. (This is our favorite crop selection to suppress nematodes),

By October 23, we clear and prepare two more beds and transplant senposai and Yukina Savoy #2 from the outdoor nursery bed.

Other Cooking Greens Tasks in Central Virginia in October

October is our month to weed and thin the fall crops in the outdoor raised beds, especially spinach and kale. We thin kale to 12” (30 cm); perhaps more space would be better, although Vates is a dwarf variety.

We put rowcover over any beds of pak choy, Chinese cabbage or Tokyo bekana we have that year. Later we weed (again!) and cover the spinach for faster growth, but leave the kale uncovered after a bad experience of Vates kale with rowcover fibers mixed in. The cooks didn’t love us!

Galinsoga dies with the frost.

We prefer to wait to cover spinach after frosts kill the galinsoga. As well as raised beds, we plant spinach in our cold frames, making good use of the space until the frames are needed in spring for hardening off transplants.

We roll, label and store drip tape from the fall broccoli and cabbage

Special Cooking Greens Topic for October: Get Soil Tests; Be Ready for Cold Nights.

October is a good month to do soil tests, when the soil is not too wet, and the soil temperatures are still warm (the soil life is active).

Weather Forecasting

We use Wunderground, but subtract 5F° from their forecast night lows for our nearest town, and mentally downgrade the chance of rain by 10%, as rain often passes us by as it scoots along the river valley north of us.

See Weatherspark.com for the typical ranges of weather in your area:

Predicting Frost

Frost is more likely at Twin Oaks if:

  • The date is after 10/14 or before 4/30 (our average first and last frost dates).
  • The Wunderground forecast low for Louisa Northside is 37°F (3°C) or less.
  • The daytime high temperature was less than 70°F (21°C).
  • The temperature at sunset is less than 50°F (10°C).
  • The sky is clear.
  • The soil is dry and cool.
  • The moon is full or new (maybe to do with tides and gravity?).
  • If temperatures are falling fast, the wind is from NW and the sky is clear, then polar air may be moving in, and we’ll get a hard freeze.
  • The dew point forecast is low, close to freezing. Frost is unlikely if the dew point is 43°F or more.

Watch for cold night temperatures and decide which crops to harvest, which to cover, which to abandon:

In a double-layer hoophouse (8F/5C warmer than outside) plants can survive 14F/8C colder than outside, without extra rowcover; with thick rowcover (1.25 ozTypar/Xavan) plants can survive at least 21F/12C colder than outside.

The hoophouse winter crops are an important part of feeding ourselves year-round

Each winter I update my Winter-kill Temperatures of Cold-Hardy Vegetables.

Here are some early winter numbers for killing temperatures outdoors (without rowcover unless otherwise stated). Your results may vary!  Let me know!        

35°F (2°C): Basil.

32°F (0°C): Beans, cucumbers, eggplant, melons, okra, peppers, tomatoes.

27°F (–3°C): Many cabbage, Sugarloaf chicory.

25°F (–4°C): Some cabbage, chervil, chicory roots for chicons and hearts, Chinese Napa cabbage, dill, endive, some fava beans, annual fennel, some Asian greens (Maruba Santoh, mizuna, most pak choy, Tokyo Bekana), some onion scallions (many varieties are hardier), radicchio.

22°F (–6°C): Some arugula (some varieties are hardier), Bright Lights chard, large leaves of lettuce (protected hearts and small plants will survive colder temperatures), rhubarb stems.

20°F (–7°C): Some beets, broccoli heads (some may be OK to 15°F/-9°C), Brussels sprouts, some cabbages (the insides may still be good even if the outer leaves are damaged), celeriac, celtuce (stem lettuce), some head lettuce, some mustards/Asian greens, flat leaf parsley (curly parsley is hardier), radishes, most turnips.

15°F (–9.5°C): Some beets, beet greens, some broccoli, some cabbage, rowcovered celery, red chard (green chard is hardy to 12°F (-11°C)), cilantro, endive, some fava beans, Russian kales, kohlrabi, some lettuce, especially medium-sized plants with 4-10 leaves, curly parsley, rutabagas if not covered, broad leaf sorrel, turnip leaves, most covered turnips, winter cress.

Cooking Greens to Harvest in Central Virginia in September

Chard and senposai are available here all month (and longer).

Some of the unusual warm weather cooking greens, such as Malabar Spinach, sweet potato vine tips, okra leaves, molokhia (Egyptian spinach, related to okra), manihot (aibika) are still edible in early September. See the July and August posts for more about those.

Yukina savoy, komatsuna, Maruba Santoh, pak choy, Tokyo Bekana and Chinese cabbage, can be available throughout September, if they were sown in late June or early July.

At last it is the season here for delicious new cooking greens! Broccoli (from 9/10), cauliflower (from 9/15), beet greens (from 9/20), cabbage (from 9/25), turnip greens (from 9/25), and collards from late September.

We may still have spring cabbage in the cooler, if we had a good harvest.

Cooking Greens to Sow in Central Virginia in September

September is a busy month for sowing greens outdoors. We want the crops to be established before cold weather, so they can make growth throughout the winter whenever it’s warm enough (anything above 40F (4.4C) is warm enough for kale, spinach and lettuce to grow a bit.).

We also prepare and plant our first hoophouse bed. That post is  an excerpt from The Year-Round Hoophouse © Pam Dawling and New Society Publishers.

Here’s our day-by-day schedule for both outdoors and our hoophouse:
  • September 6: Direct sow in the hoophouse: spinach #1, tatsoi, Bulls Blood beets
  • September 7: Last date for first round of kale sowings outdoors.
  • By September 15: Sow outdoors if not done yet: kohlrabi, kale and collards; Hoop and net.
  • Early-mid September: Sow spinach #1 outdoors (pre-sprouted). We have trialed various spinach varieties for our hoophouse and for outdoors, and our current favorites are Reflect (outdoors) and Acadia (both outdoors and in the hoophouse).
  • September 15: our first round of nursery sowings for the hoophouse: pak choy, Chinese cabbage, Yukina Savoy, Tokyo bekana, chard, (as well as lettuce and frilly mustards for salad mixes). Two or three times in September we sow crops in an outdoor bed to be bare-root transplanted at about 3 weeks old into newly prepared hoophouse beds. This gives the warm weather hoophouse crops (including cover crops) longer to grow, and also gives the seeds cooler conditions to germinate in. Because the pest pressure outdoors is fierce at that time of year, we hoop and net these very important plants. Our rough formula for all transplanted fall brassicas is to sow around a foot (30 cm) of seed row for every 12’–15’ (3.6–4.6 m) of crop row, aiming for three seeds per inch (about 1 cm apart).
  • September 15 is our last date for resowing kale outdoors, if we are to get any winter harvests from it.
  • Mid-September: Sow spinach in the coldframes. In spring we will use the coldframes to harden off seedlings, but over the winter they make a nice sheltered space to grow more spinach. We will cover the coldframes in the middle of winter. An advantage of using the coldframes for spinach is that the area around the frames is all mulched, and accessible regardless of the weather.
  • By mid-September: Sow turnips outdoors, hoop and net them.
  • September 20-30: Sow spinach #2 outdoors for spring harvest. The goal here is to provide a succession of spinach harvests. This later sowing will size up in early spring and give good harvests before the newly transplanted spring spinach, and be better quality and more abundant than the beds sown in early September.
  • September 24: nursery sowings #2 for the hoophouse: we first -resow any failed #1 sowings; and also sow Red Russian kale, White Russian kale, senposai, Yukina Savoy, Frilly Mustards, and more lettuce. We hoop and net.
  • Late September: Sow Eat-All Greens See the Special Topic for September below.
  • September 30: As needed we resow any of the hoophouse transplants that we are short of.

Cooking Greens to Transplant in Central Virginia in September

In early September, we transplant collards and kale if we didn’t finish in August.

We only grow Vates kale, a very cold-hardy dwarf Scotch curled type outdoors. When the kale is about 3-4 weeks old, we use plants from any of the beds to fill out any other (if we have enough spare plants). We resow if the survival rate is really poor. We eat any extra plants.

In late September, we finish the kale gap-filling. From then on, what we see is what we’ll get.

Other Cooking Greens Tasks in Central Virginia in September

Weed and thin kale to 12”

To improve spinach seed germination we have put spinach seeds in the freezer in mid-August or earlier (at least two weeks). We reclaim it from the freezer and let the waterproof container warn up to ambient temperatures before opening it. Otherwise condensation will land on the seeds and ruin them for future sowings.

To presprout spinach, measure the required amount of seed, put it in a jar and cover with water overnight. Fit a mesh screen lid (a piece of window screen held on a Mason jar by the metal band works well, although you can buy longer-lasting metal or plastic mesh lids too. In the morning, strain off the water, turn the jar on its side, shake out the seeds to lie along the side of the jar, and lay the jar in the fridge. Once a day, give the jar a quarter turn to shuffle the seeds and even out the moisture. You are not growing bean sprouts, and you do not need to rinse and drain the spinach seeds. After 6 or 7 days, the seeds will have sprouted enough to plant by hand. Perhaps spread the seeds to dry for an hour on a tray or a cloth. If the seeds stick together as you start to plant, mix in a little dry, inert, absorbent material like uncooked corn grits, bran or oatmeal (but not sticky bread flour).

Beet seeds can also be presprouted, but a bit more care is needed, as it is easy to drown beet seeds. Soak them in water for only an hour or two, and do not use much more water than needed. I realize that’s a tall order the first time you do this, as you won’t know how much is too much! Err on the side of caution! Don’t let the sprouts grow very long, as they are brittle. A short red sprout is all you need.

Special Cooking Greens Topic for September: Eat-All Greens

I introduced the topic of Virginian Eat-All Greens in my blog in November 2015.

Carol Deppe, in her delightful book The Tao of Vegetable Gardening explained the concept and the practice of growing Eat-All Greens. Carol grows these by broadcasting seed of one of her carefully chosen greens crops in a small patch. When it reaches 12″ tall, she cuts the top 9″ off for cooking, leaving the tough-stemmed lower part, perhaps for a second cut, or to return to the soil. I wanted to try this idea in Virginia, where the climate is fairly different from the Pacific Northwest where Carol lives. I decided fall was a promising time of year to try this scheme, and we sowed some on September 16 that year. We hadn’t planned ahead, and didn’t have the perfect range of seeds (see The Tao of Vegetable Gardening for that). We experimented with seeds we had on hand or could get quickly, and we sowed in rows rather than broadcast, because we knew we had a lot of weed seeds in the soil.

Carol Deppe has an article on How to Easily Grow High-Yielding Greens in Mother Earth News Feb/March 2016, which you can read about here

We harvested in October and for the third time on 11/3, and several more times. By December 22, I was noting “Our Eat-All Greens are still alive, if not exactly thriving. The peas have been harvested to death; the kohlrabi, beets and chards are never going to amount to anything; some of the more tender Asian mustard greens are showing some frost damage. On 12/10 we made one last crew foray to harvest – not greens, but roots!” We harvested two and half buckets of radishes and 5 gallons of turnips before the end of the year. I’m not sure how many harvests of cooking greens we’d had, but it felt plentiful..

Some Eat-All Greens in early November.

On January 12 I noted: “We had a low temperature of 6F on January 5th. Not much [of the Eat-All Greens patch] is left alive. Always enthusiastic to keep updating my list of cold-hardy winter vegetable crops, I took my notebook and walked the rows a few days later.”

I wrote up our Eat-All Greens for Growing for Market magazine and you can read it in the January 2016 issue. We thoroughly enjoyed the experiment, and the sight of all those rows of abundant greens in the late fall and early winter.

SSAWG Conference, Mother Earth News and Eat-All Greens, Growing for Market

I’m home from a very successful Southern Sustainable Agriculture Working Group (SSAWG) Practical Tools and Solutions for Sustaining Family Farms Conference in Lexington Kentucky. It was the biggest so far, with 1400-1500 participants. My workshop Intensive Vegetable Production on a Small Scale ran out even of standing room, so I was asked to repeat it in the afternoon. I did that and the new room was half full. I gave out over 230 handouts. The impossibly broad topic was a challenge for a 75 minute workshop, but I did my best. Last week I blogged the info on Bio-intensive Integrated Pest Management that I had to drop from the slideshow.

I love the SSAWG conference. I learned so many useful tips that will improve my farming this year and in the future. Such as another way to tell a ripe watermelon: stroke it and feel the texture of the skin. If it’s slick the melon isn’t ready. When it becomes a little rough, it is. Such as, yes a 60cfm inflation blower really should be adequate for a 30′ x 96′ hoophouse, so we almost certainly have holes in the plastic. Such as ways to deal with tomato diseases in the Southeast (thanks Joe Kemble of Auburn University).

If you are now wishing you’d been there, go to SlideShare.net and search for SSAWG. There are so many valuable presentations from conferences over the years. Also the audio of this year’s presentations (and last) are available from Rhino Technologies. Wait a few days for them to get home and load everything on their website.

And while the soil outside is waterlogged and you can’t do much gardening or farming, what better than more veggie-reading? Mother Earth News Feb/March issue has an article by Carol Deppe,  on How to Easily Grow High-Yielding Greens. Carol is the inventor/discoverer of Eat-All Greens, which I have been writing about on this blog. Her 20 years of trialing this method of growing cooking greens quickly with very little work has led her to now recommend seven greens as particularly suitable. Green Wave mustard, Shunkyo and Sensai radishes (I was interested to read that Carol also harvested the radish roots as we did with ours in December), Groninger Blue collard-kale (must get that this year), Burgundy amaranth, Tokyo bekana (check!), and Red Aztec huazontle. No mention this time of peas. Peas provided our earliest harvests this fall. Keeping them tender was a challenge though. The article includes information on where to buy the varieties she recommends. Carol also has her own seed company Fertile Valley Seeds, selling varieties and strains that she has developed.

In the same issue of Mother Earth News is some of what I have written about dealing safely with green potatoes.

GFM_February2016_cover_300pxLastly for this week, the February Growing for Market is out. This is the first issue from the new editor, Andrew Mefferd. He tackles the thorny topic of hydroponics and whether it can ever be considered Organic. (Many organic and biological growers believe it is important to Keep the Soil in Organic)  As well as the Organic status of hydroponics, he describes the various types of hydroponic production for those that want to grow food that way, and for the rest of us to understand what we are talking about.

There is an article by Nick Burton about his hydroponic system and developing a trust-based sales system in a gym for people on a “paleo diet”, who eat lots of vegetables. Then a salad mix kit. He had moved from running a plant nursery to selling produce to selling convenience for people short of time and enthusiasm for shopping and preparing food. I admit to being skeptical about the paleo diet. Didn’t those paleo people spend all day scavenging for food?

Gretel Adams writes about running a bouquet business efficiently. (I’d be no good, I would dither for too long!)

My own article this issue is very down-to-earth: growing oats as a cover crop. They are easy-care and in climates in zone 7 or colder, they reliably die in the winter, making for easy early spring cultivation. We like to undersow oats and soy in our last sweet corn patch. This saves us from having to disk up the patch to establish a winter cover crop (it’s already there!), and means we can follow the late sweet corn with an early spring crop the next year. In our case it is the March potatoes.

I wrote about our Eat-All Greens in November and December. Here’s the last installment for this season. We had a low temperature of 6F on January 5th. Not much is left alive. Always enthusiastic to keep updating my list of cold-hardy winter vegetable crops, I took my notebook and walked the rows a few days later. Here’s a (short) list of the survivors:

Best was (were?) the Morris Heading collards. We grow these overwinter in our garden too, and we are enjoying eating those. This photo shows young plants before they reached full size.

Also still showing some life were Purple Top White Globe turnips, Ortolani Market Grower arugula and some (not all) of the Hanover kale (which is after all, a Siberian spring kale, not recommended for over-winter growing).

It will be interesting to see if any of these survive until mid-February, when we will need to disk the plot (El Nino willing) to plant some new grape vines along one side. This plot is also my back-up area in case the plot where we want to plant our spring cabbage and broccoli is too wet when the time comes. The rotation puts these in the wettest part of our gardens.

I have written up our Eat-All Greens for Growing for Market magazine and you can read it in the January issue.

In this issue you can also read an article by the new editor Andrew Mefferd about growing microgreens. I’ve never grown these, so I valued getting professional tips from someone who has. How not to grow them (sowing too thickly, using expensive potting soil when you don’t need to, over-watering, under-ventilating.

GfM January 2016
GfM January 2016

He also includes tips on which seeds are best for microgreens, and how to tidily harvest. If you want to add microgreens to your market crops, a sub to Growing for Market will repay you pretty quickly with just this one article. And if you are growing them at home, it will save you lots of frustration.

The long-time editor, Lynn Byczynski, who is retiring, has an article about growing turmeric, which has similar growing requirements to ginger (but a bit easier). Eric and Joanna Reuter have written about raising shiitakes for market. Gretel Adams has written about selling cut flowers to supermarkets, which has served her as a good way to increase sales volume. All good inspirational reading while the weather doesn’t encourage working outdoors!

Ate more Eat-All Greens; Changed vegetable crop rotation

Our Eat-All Greens are still alive, if not exactly thriving. The peas have been harvested to death; the kohlrabi, beets and chards are never going to amount to anything; some of the more tender Asian mustard greens are showing some frost damage.

On 12/10 we made one last crew foray to harvest – not greens, but roots! I’d noticed in the wet mild weather of late November the radishes and turnips had fattened up. We can always use a few more turnips, I thought. Plus, I was inspired by the quick-pickle radishes we’d had recently. See sustainexistence – sustainable sustenance for our existence, the local foodie blog written by one of my fellow Twin Oakers. 

As we were harvesting the two and a half buckets of radishes, someone came by who said he was planning to pickle radishes, so I told him we’d keep him busy! (Actually, ten days later, there are many left to deal within the walk-in cooler.) The daikons predictably did well, as they are a fall crop. Other good varieties included Crimson Giant, which I picked up at a seed swap, and White Icicle. Sparkler (a small radish was unsurprisingly tough and woody at this overgrown stage.

We also pulled a 5-gallon bucket of delectable small turnips, including some rather pretty Mezza Lunga Bianca Colletto Viola from Seeds from Italy.

Meanwhile we have been working on our garden planning for next year. Back in 1996 we devised a 10-plot crop rotation, which has generally served us very well for 19 years. The first few years we tweaked it a bit, but we haven’t needed major changes. You can see our pinwheel rotation plan in my book Sustainable Market Farming and in my slideshow Crop Rotations for Vegetables and Cover Crops  on SlideShare.net.

Here you can see the original card version, complete with modifications. The central card disk is fastened with one of those brass-legged paperclips and can be turned one notch each year.

The bit we want to change is the fast-turnaround where the spring potatoes are followed by the fall broccoli and cabbage. This has worked well in terms of getting high usage from our land, and freeing up one plot in ten to be Green Fallow (all-year cover crops). We did that by undersowing the fall brassicas with clover about a month after transplanting, and then letting the clovers grow for a year and a half before disking in. The difficulties with such a fast turnaround in July are

  1. If we have a wet spring, and we plant the potatoes late, we have to terminate them early (by mowing the tops) and the yield isn’t as good as it might have been. Climate change suggests we might be in for more wet springs, and with El Nino upon us, this is a good time to switch.
  2. If the weather doesn’t co-operate in July, the soil might be too wet to harvest the potatoes when we want to, and too wet to disk in preparation for the transplanting. We need to build more climate resilience into our rotation!
  3. July is stressful enough – it’s hot and humid, people are taking their turn at having a vacation.
  4. If we are late transplanting the broccoli and cabbage, the plants are oversize and don’t do well, so we get reduced yields of broccoli and cabbage that year.
  5. We prefer transplanting in the evenings in the summer (cooler for us and for the plants), and if we get late into August, the daylight is getting too short to get much done.

And so, we are seizing the opportunity to make the switch. The opportunity comes because for the last several years we have not needed to grow winter squash in the vegetable garden because it is grown elsewhere on the farm by the Twin Oaks Seeds.

Our crop rotation contains several sequences of crops that we want to keep. For example, Fall brassicas/Green Fallow/early spring crop (Could be corn or potatoes, but not the spring broccoli and cabbage). Another sequence that works well for us is the Early corn/Garlic next to spring brassicas/fall carrots in one half, rye vetch and peas for no-till cover crop in the other half/paste tomatoes on the no-till the next year.

What we’ve planned for next year (a transition to our new plan) is to use the former winter squash plot for the fall brassicas/clover bit. This involves snipping that plot out of the pie and moving it after the corn #6/sweet potato and the spring potato/cantaloupe (which had morphed into 100% potatoes over the years), so that the newly housed fall brassicas can be followed by the clover year.

But that leaves potatoes only two years after other potatoes, and the late corn only two years after the middle corn, so we don’t want to do that more than once! So for 2017 onwards, we plan to insert the late corn & sweet potato/spring potato sequence after the clover, and move the early corn after the spring potatoes (when we have time to plant a winter-killed cover crop and make cultivation for the early corn easy). And switch the watermelon piece of the pie with the 3rd, 4th and 5th sweet corn successions to even out the years between corn patches.

This will give potatoes, tomatoes, potatoes 3 or 4 years before the plot is nightshades again. With the corn  we get 3 years, 5 years and 2 years. Not ideal. But we don’t get much in the way of corn diseases (compared to tomato diseases) so it seems the best place to compromise.

If you get bored with holiday jigsaw puzzles and TV offerings, you could draw up your own version of our rotation, chop it up and rearrange it, and send us you suggestions. Remember to plan the winter cover crops too! Have fun!

Meanwhile, here and now, on the ground, a photo of our much-beloved Ruby Streaks, in our Eat-All Greens patch, being used as salad greens.

Virginian Eat-All Greens

Carol Deppe, in her delightful book The Tao of Vegetable Gardening introduces us to the concept of Eat-All Greens. Carol grows these by broadcasting seed of one of her carefully chosen greens crops in a small patch. When it reaches 12″ tall, she cuts the top 9″ off for cooking, leaving the tough-stemmed lower part, perhaps for a second cut, or to return to the soil. I wanted to try this idea in Virginia, where the climate is fairly different from the Pacific Northwest where Carol lives.

I decided fall was a promising time of year to try this scheme, as our spring planted greens only have a short season before they bolt. And summer is too hot, winter too cold. . . We sowed in mid-September, and are about to make our third harvesting foray. Unlike Carol, we sowed our greens in rows side by side. This fitted better with the space we had, a large rectangle where our asparagus used to be. The organic matter content of the soil is lovely, as we used to mulch the asparagus with hay twice a year. But the weed seed-bank is awful! After each asparagus harvest season we let the ferns grow up and the plot became impenetrable. So we got lots of summer weeds, especially morning glories and cocklebur. After about 12 years or so, we decided to give up on that asparagus patch and grow a series of cover crops until we got the weeds under control again. Having the Eat-All Greens in rows, and hoeing between the rows, fit that strategy nicely.

We sowed on 9/16. I had a lot of help that day. Somehow the seed got sowed very thickly. Carol recommends leaf or pod radishes, some beets, some chards, quinoa, some mustards, some snow peas, some Napus kales, some amaranths, some leafy Asian greens (mustards but less spicy). She has put a lot of research into which grow best – see her book for the details. We decided to use some seeds we had on hand and some we got given, that resembled the things Carol recommends. We didn’t want to invest a lot of money first time around, nor wait for a seed company to fill our order. We knew our results wouldn’t be the same as if we lived in the Pacific Northwest anyway.

Most of the seeds emerged by 9/21 (5 days), and we hoed between the (wavy) rows on 9/23. We also thinned some of the radishes, because they were sown too thickly. The fava beans didn’t come up till 9/30, but then they grew fast, and became one of the first crops big enough to harvest. Eating the tips of fava bean plants is a practice I learned in England, so I knew these unusual plants are edible. I noticed the beets and chards are all slow-growing in our climate at this time of year, as are the kohlrabi. We had lots of seed of Early Purple Vienna kohlrabi and the seedlings are so pretty I thought they might work for Eat-All Greens, but no, not at this time of year anyway..

We got our first harvest on 10/21, 35 days after sowing. The biggest varieties were the fava beans (seed we’d bought, then decided not to grow) and dwarf grey sugar snow peas (seed from last year – we don’t like these as snow peas any more). We cut along the rows with scissors. People found it hard to cut at 3″, high enough to leave the tough stem behind. I noticed we all tended to cut low. The plan was to lay the cut greens in shallow crates with the stems all aligned to make it easier for the cooks. Some people didn’t do this with the peas, putting them in a big mat in the crate. The peas got served raw, which wasn’t my intention. The stems were too tough for most people – even for cooking, we should have cut higher. We got 3 cratefuls, a generous amount, which we didn’t make the best use of, despite an instructional label. Presentation and instructions are our version of marketing to our cooks.

One week later (10/28) we went for our second harvest. By then the radishes had clearly come into their own, and one of the rows of dwarf grey peas that we harvested the week before had already made enough growth for a second cut. You can see in the photo above the big difference in growth rate between the radishes and everything else. The harvest was bigger than we’d hoped for. We got 10 crates and two very stuffed 5-gal buckets we decided to give to the chickens as a sign of our appreciation.

What next? I ‘m looking forward to the Maruba Santoh, and the Ruby Streaks especially. But we have to explain more carefully how these should be cooked, to people unaccustomed to cooking mixed greens. And we need to switch to more frequent forays and smaller harvests at a time. And cut higher up the stems. And then, it depends on the weather. The kohlrabi already got some frost damage. Currently the nights are mostly above freezing. Some of these crops are good down to 25F, some better than that.

I’m already thinking what would I do different if we do this again. No chards, no beets, no kohlrabi. Thinner seed sowing, straighter rows (easier hoeing). Try some other Asian greens? Buy some of the specific varieties that Carol Deppe recommends. Maybe sow a week earlier. And a smaller patch! It’s being fun!
