This is my monthly series of 14 Workhorse Crops (asparagus, beans, cabbage, carrots, chard, collards/kale, garlic, potatoes, sweet corn, sweet potatoes, tomatoes, watermelons, winter squash, zucchini/summer squash). These crops are reliable and productive under a range of conditions. You can use the search box to find previous month’s entries, such as January.

At last the daylight is getting noticeably longer, although we still have very cold weather. We reach 10 hours of daylight on January 21, and 11 hours on February 20. In our hoophouse we are clearing crops before they bolt, and planting some quick crops before the warm weather ones go in in March and April. In the greenhouse we are starting seedlings and clearing lettuce that is thinking about bolting. Our seed orders are arriving and we are finishing up our various planting schedules and crop maps.

Carrots

We sow carrots in mid-February, and again at the end of February. Yes, they take a long time to emerge when the soil is still so cold. But it’s a task we can get done now, and won’t have to do later, when we are busier. Carrots take 50 days to emerge at 41˚F (5˚C), (although of course it will have warmed up some before 50 days pass!); 17 days at 50˚F(10˚C); 10 days at 59˚F (15˚C); 7 days at 68˚F (20˚C); 6 at 77˚F (25˚C); 5 at 86˚F (30˚C) and don’t try hotter than that!

We use an EarthWay seeder and the Light Carrot plate (although that still puts out lots of seed!) We can’t really justify the cost of a precision seeder like the Jang, for the amount we’d use it.

Asparagus

If you are planning to start a new asparagus patch, early spring is the best time to plant. This will give them as much time as possible that first year, to grow strong roots. The usual suggestion is to plant at least 10 crowns per diner.

Most growers purchase two-year-old crowns, although it is possible to grow your own asparagus from seed, if you can find seed of your preferred variety. The old OP varieties are still available, but newer all-male hybrids yield far more heavily, often more than twice as much. We chose Jersey Giant, a male hybrid resistant to asparagus rust and well-adapted to the mid-Atlantic. It produces big, tender, succulent spears each spring.

The best soil temperature for planting asparagus is 50°F (10°C) –  planting in cold soil encourages disease and offers no advantage. Remove shipped asparagus roots from the box as soon as they arrive, and untie the bundles. Don’t water them. If you need to store the roots longer than two weeks, spread them in trays or crates, in a cool, fairly dry place, until planting conditions are right. You can read more about growing asparagus in Sustainable Market Farming, and my recent article in Growing for Market magazine.

Indoor sowings for later transplanting outside or in the hoophouse

In our greenhouse we have started a couple of flats of fast-maturing cabbage. We like Farao (60d) and Early Jersey Wakefield (63d). Both numbers are seed to harvest. Subtract 20 days if counting from transplanting to maturity.

We have already sown our kale and collards for outdoor spring crops, in our hoophouse. Here’s the info on that: On January 24 we sow Vates kale and Morris Heading collards in the ground in the hoophouse, in the space recently freed up by the Chinese cabbage. For 1080ft outdoors, we need 108ft of seedling rows. We can fit 14 rows of seedlings across a 4ft (1.2 m) bed. We will transplant these outdoors as bare root transplants in mid-March.

We don’t sow our chard and leaf beet until 3/24, because we want them for summer greens, after the kale, collards, broccoli and Asian greens have all bolted. But you can start them earlier, if you want earlier harvests. I’ll say more next month about chard, but if you want to get a start sooner, know that the seed will germinate from 41°F (5°C) to 95°F (35°C), and the best temperature is 86°F (30°C), when it needs only 4 days to pop up.

Hoophouse workhorse crops to plant in February

We do sow a few hoophouse greens successions during February, a row of snap peas, some lettuce mix, but nothing that qualifies as a Workhorse.

Collards and Kale can be lightly harvested outdoors here in February. About once per bed during each of the coldest months, January and February. We’ll be able to harvest those beds once a week each in March. Our mnemonic for sustainable harvesting of leafy greens is “8 for later”, meaning we leave at least eight inner leaves when harvesting the outer ones, to ensure the plants have enough strength to regrow.

Overwintered Carrots and Cabbage are a possibility some years, but not this one! I actually prefer to get all our carrots safely harvested and stored, rather than have them still in the ground, where more things can go wrong! We have had 3 nights in January down to 10°F (-12°C), and I don’t think even Deadon cabbage would survive that many cold nights! Some of our Tadorna leeks are looking quite damaged. We don’t usually have that problem.

Hoophouse Workhorse Harvests in February

Bulls blood beet greens, chard, and some greens not in our Workhorse group, (turnip greens, Yukina Savoy, spinach) are still going strong. Our experimental carrots are still doing OK, although I’m not a fan of giving them hoophouse space for such a long time with no harvests. I notice I’m slipping into mentioning non-workhorses more often now the winter is biting us.

At last we can start harvesting our Russian kales in the hoophouse. We were late getting them established last fall, and growth has been slow. Now many of the other greens (Tokyo bekana, Napa cabbage, pak choy, the first tatsoi and the first mizuna) have all been eaten, we are very ready for the kale. Russian kale wilts easily and is best harvested into buckets as if a bouquet of flowers, with a little water in the bucket.

Workhorse Crops from storage in February

From storage in February we can eat carrots, garlic, potatoes, sweet potatoes, winter squash. Also frozen summer goodies, and pickled things, sauerkraut, pickled beans, and canned goods like salsa.

Workhorse Crops Special Topics for February: Phenology

I wrote about seed germination temperatures and phenology signs in April 2021. I have an earlier post about phenology here, and one about Harbinger Weeds of Spring.

Certain natural phenomena are related to the accumulated warmth of the season (rather than, say, the day-length), and by paying attention to nature’s calendar you will be in sync with actual conditions, which vary from year to year, and are changing over a longer time-scale.

You can learn when to plant by natural signs. For instance, we sow sweet corn when white oak leaves are the size of a squirrel’s ear. I got excited one weekend (April 10) when I saw wind-driven twigs on the ground with oak leaves definitely bigger than squirrels’ ears. But they were Red Oak, not White Oak.

Keeping your own phenology record is a useful guide to when to plant certain crops, and a way to track how fast the season is progressing right where you are. Phenology involves recording when certain wild and cultivated flowers bloom, seedlings emerge, or various insects are first seen. These natural events can substitute for Growing Degree Day calculations. Your phenology record will help build resilience in the face of climate change. Ours might be interesting to you, but unless you live in central Virginia, you can’t use our dates. You do need to make your own. This can be a great home-schooling project, or a crew I-Spy competition, or a calming end-of-day walk around your gardens.

Cooking Greens to Harvest in Central Virginia in February

Harvest in Time! Lots of Bolting Greens in the Hoophouse!

Outdoors, we can still harvest collards, kale and spinach. This winter our chard has died. Remember that red chard is hardier than multi-colored and green chard is hardier still. To maximize your chance of keeping chard alive over the winter, use hoops and rowcovers (in zone 6-8) or, in colder zones, cut the tops off the plants (above the growing point) before it gets much below 15F (-9C), remove those leaves, then cover the bed with a mulch of thick straw, hay or tree leaves. Mulching doesn’t work in milder climates, especially those with back-and-forth temperatures) because new growth forces up out of the mulch and gets killed.

From the hoophouse we continue harvesting chard, Frills, kale, senposai, spinach, tat soi, turnip greens, and also yukina savoy (if we had it). We normally grow the Frills as salad crops, but once they get large and plentiful, we can cook some.

In the hoophouse, the extra warmth (sometimes!) combined with the reliably lengthening days causes some of the greens to start bolting. In January, I told you the order of bolting of our hoophouse greens. Our Koji has all bolted by February 1, and I pine for Yukina Savoy which usually lasts till early-mid March here, from our second winter sowing. We didn’t have any this winter.

We are keeping an eye on our turnip greens #1 (they will bolt in mid-February); tatsoi #2, spinach #1, and turnip greens #2 (usually bolt in early March). Our senposai and our turnips #3 usually don’t bolt till mid-March. Our Russian kales, chard, beet greens and January spinach sowings last till late April or even early May.

Hoophouse turnips have delicious greens too!

Cooking Greens to Sow in Central Virginia in February

Outdoors in mid-February, we sow spinach if our January transplant sowings failed. We presprout 4oz/bed spinach for 1 week before sowing. This rarely needs to happen, as we have a backup transplant sowing date to seed in flats in the greenhouse, if our first-line hoophouse sowing of transplants doesn’t come up well. This year, those look great!

In the greenhouse in early February, we sow: kale, cabbage, mustard, collards, senposai, broccoli #1, kohlrabi in open 3” (7.5 cm) flats.

In late February, we sow broccoli #2. This year we have reduced the size of our planting to make it more manageable.

In the hoophouse, December 15-February 15 is the slowest growing time. We do sow some salad crops, but not usually any cooking greens. if the January hoophouse sowings of kale and collards have come up well, we don’t need to sow those in the greenhouse this year.

We have a couple of unexpected gaps this year. We followed Radish #2.5 (an extra sowing we squeezed in on October 20) with Frills (frilly mustards) and we plan to follow some of our Koji #2 with a quick catch crop of Tokyo Bekana, marking five rows in the bed, but leaving the central row unsown. This will hopefully let us leave the greens growing after we transplant the warm weather crops down the centerline of the bed.

Young Ruby Streaks, Golden Frills and Scarlet Frills provide continuous harvest after the older ones bolt.

Cooking Greens to Transplant in Central Virginia in February

Outdoors, we transplant spinach from hoophouse [or flats] in early February

In the hoophouse, from January 25 to February 20 we fill gaps that occur in the beds with spinach wherever the gaps are, using the spinach Filler Greens which were sown October 24 and November 9 (spinach). We’re careful not to fill any places that will be sown in new crops in February, such as where we sow a row of early snap peas, or the salad crops I mentioned earlier.

From February 20, we only transplant spinach to fill gaps on the outer thirds of the beds, leaving the bed centers free for tomatoes, etc. in mid-March.

Other Cooking Greens Tasks in Central Virginia in February

In early February in the greenhouse we spot cabbage and kale. In late February, we spot senposai, cabbage #2 and collards. See the Special Topic below for more about the task we call ”spotting”. Other names for this task include “bumping up”and “pricking out.”

We really try to finish transplanting spinach outdoors, as our springs are short and quickly heat up, taking the spinach plants with them.

We weed our over-wintered spinach, kale and collards. Hoeing isn’t so effective in early spring, as the chickweed, henbit and dead nettle too readily re-root on damp soil. Hand-pulling weeds is slow, but more effective. Another approach is to hoe several times, choosing dry breezy sunny days.

During January we had two nights at 13F (-10.5C) and 12F (-11C). The Koji are looking quite damaged, beyond marketable but not beyond salvageable for home use. We grew too much of this, so we still have plenty to eat! The outdoor senposai is also damaged, but as this is a loose-leaf crop it could recover if it doesn’t get colder.

As I reported in January, we didn’t cover the spinach this winter, because of issues with rowcover fibers getting in the food. The plants are looking quite small, while those in the coldframes (with rowcover) are growing well. I have been expecting the growth of the uncovered spinach to be a lot slower, as spinach (like kale and lettuce) makes some growth whenever the temperature is 40°F (4.5°C) or more. 10°F (-12°C) could kill the large leaves and 5°F (-15°C) can kill spinach entirely. So far, temperatures haven’t get that cold this winter.

Special Cooking Greens Topic for February:

Planning our Field Planting Schedule.

In January we prepare our new Seedlings Schedule, then our complex Fall Brassica Spreadsheet and Map, Field Planting Schedule, Hoophouse Schedule for March to September crops (those are not cooking greens!), and then our Raised Bed Plan and our monthly Garden Calendar.

Field Planting Schedule:

We allow 6 hours. We bring the previous year’s greenhouse copy of the Seedlings Schedule, the shed copies (the copies we wrote notes on) of the previous year’s Field Planting Schedule and the shed and seed bucket copies of the Lettuce Log. We also bring the new (current year’s) Fall Brassica Schedule, Seedlings Schedule, Seed Order, Garden Plan, Rotation Plan, Maps, Succession Crop Plan, Sweet Corn Plan, Brassica Plan and Tomato Plan and any notes we made while doing the year’s planning so far.

  1. We work in Excel, copying last year’s Schedule to a new Worksheet and modifying that.
  2. We highlight and clear the contents of the“Location” column (Crop rotation in action!)
  3. We check against last year’s Shed copy and Field Manual copy of the Field Schedule. As we go, we make a list of questions or points to fix later.
  4. We check against the Seedlings Schedule for last year and the current year, for transplant date and varieties, row feet of the transplanted crops. (Leave the direct seeded crops varieties and row feet for step 6).
  5. Next we highlight the data, sort alphabetically by Vegetable, Variety to make the next stages easier.
  6. We check against the Seed Order (and Succession Plan as needed) for varieties and row feet of direct seeded crops.
  7. We check against the Tomato Plan for main crop and late bed.
  8. We check against the Garden Rotation Plan, Maps and Succession Crop Plan.
  9. We fill gaps in the Location column, in In-row Spacing and Space Between Rows cols.
  10. We check against Fall Brassica Schedule from the current or previous year, revising sowing dates, row feet, transplanting dates.
  11. We check against the Lettuce Log.
  12. We check against Hoophouse Schedule, for transplants in and out.
  13. We clean up the Notes column keeping useful info, adding any new useful info, checking against running list of things to fix.
  14. With all that done, we sort by Transplant date; then by Vegetable, then by Variety.
  15. We tidy up the page layout and print a draft copy
  16. We proofread and fix anything that didn’t make sense.
