Winter radishes, planting garlic.

Our main task this week has been planting garlic, both hardneck and softneck. As we separated the cloves for planting, we put all the tiny cloves (which wouldn’t grow big bulbs) into small buckets. We use these to grow garlic scallions. Planting them is next on our list.

Garlic scallions are small whole garlic plants, pulled and bunched in the spring like onion scallions. They are chopped and cooked in stir-fries and other dishes. They are mostly green leaves at that point, although the remains of the clove can also be eaten. Hard-core garlic lovers eat them raw like onion scallions. They provide an attractive early spring crop.

To grow garlic scallions,  plant small cloves close together in furrows, simply dropping them in almost shoulder to shoulder, any way up that they fall. (If you’ve just finished a large planting of main-crop garlic, you’ll probably be too tired to fuss with them anyway!) Close the furrow and mulch over the top with spoiled hay or straw.

You could plant these next to your main garlic patch, or in a part of the garden that’s easily accessible for harvest in spring. Or you could plant your regular garlic patch with cloves at half the usual spacing and pull out every other one early. Think about quantities, though. If we double planted, we’d have over 7000 scallions, far more than we could use. The danger with double planting is stunting the size of your main crop by not thinning out the ones intended for scallions soon enough. We plant our small cloves for scallions at one edge of the garden, and as we harvest, we use the weed-free area revealed to sow the lettuce seedlings for that week.

With a last frost date of 20-30 April, we harvest garlic scallions from early March until May,  depending on how long our supply lasts out, and when we need the space for something else. Harvesting is simple, although depending on your soil, you may need to loosen the plants with a fork rather than just pulling. Trim the roots, rinse, bundle, set in a small bucket with a little water, and you’re done! Some people cut the greens at 10″ (25 cm) tall, and bunch them, allowing cuts to be made every two or three weeks. We tried this, but prefer to simply pull the whole plant once it reaches about 7-8″ (18-20 cm) tall. The leaves keep in better condition if still attached to the clove. Scallions can be sold in small bunches of 3-6 depending on size. If you do have more than you can sell in the spring, you could chop and dry them, or make pesto, for sale later in the year.

This week we also harvested our winter storage radishes, which we sowed in July. Winter radish varieties have large roots that may be round or long, with white, red, pink, green or black skin. They can be eaten raw, pickled, mixed in stir-fries or cooked like turnips. Our favorites are:

  • Shunkyo Semi-long  (32 days, OP), 4-5″ (10-12 cm), smooth, cylindrical, attractive rose-pink roots with crisp white flesh. The flavor is hot and sweetly nutty. The pink-stemmed leaves can also be eaten. This slow bolting variety can be sown throughout the year in mild climates.

The other varieties in this list are all day-length sensitive, for summer to fall sowing only. They bolt if sown in spring.

  • China Rose (55 days, OP). AKA Rose Colored Chinese, Scarlet China Winter. About 5″ (12 cm) in diameter. Round, with white flesh, pink skin. Cosmetically, this variety is more variable and less beautiful than Shunkyo.
  • Red Meat (50 days, OP). AKA Watermelon. Large round roots, 2-4″ (5-10 cm), depending on how long you let them grow. Green and white skin, with sweet dark pink flesh. Large leaves.
  • Misato Rose (60 days, OP). AKA Chinese Red Heart. Green and white skin, rose and white “starburst” flesh. Beautiful when sliced for salads. Unlike many radishes, this one will still bulb properly if crowded, according to Southern Exposure Seed Exchange. Attractive, spicy, not sharp, with “a rich sweet vegetable undertone.” Can grow as large as a big beet if given sufficient space. A good keeper.
  • Shinden Risoh Daikon (65 days F-1 hybrid). Daikon (pronounced “dye-kon”) is the Japanese word for radish. Daikon are huge long white roots which store very well and stay crisp for months under refrigeration. They can be grated or sliced thin for salads, pickled, or sliced and chopped for stir-fries. Kim Chee is a traditional Korean pickle made with daikon and napa Chinese cabbage. Daikon can also be harvested small.
  • Miyashige Daikon (50 days, OP). 16-18″ (40-45 cm) long by 2.5-3″ (6-8 cm) in diameter. These “stump-rooted” cylindrical white radishes are pale green near the crown. Very crisp and tender for pickling and storage.

This year we grew 45′ each of Shunkyo Semi-Long, China Rose, Red Meat and Shindin Risoh Daikon. In terms of yield, the China Rose is the clear winner: 54 lbs from 45′.

And they look very smooth and attractive. Next best in yield was the other pink one, Shunkyo Semi-Long at 25 lbs. The daikon came in at 21 lbs, lower than I expected. Maybe we should have thinned more drastically. A big disappointment was the Red Meat at only 15 lbs. Mind you, this one sells itself on its impressive looks. See the picture above.

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

During the month

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

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

Frost Alert:

Watch the forecast and if frost is expected that night

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

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

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

Spring hoop and cover: squash, cucumbers.

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

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

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

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

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

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

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

Roll up drip tape from winter squash and sweet potatoes.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Time to say goodbye to the rhubarb until April.

October Harvests: Asparagus beans, beans, beets and beet greens, broccoli, cabbage, cantaloupes, carrots, cauliflower, celeriac, celery, chard, Chinese cabbage, collards, corn, cow peas, cukes, edamame, eggplant, horseradish, hot peppers, kohlrabi, komatsuna, leeks, lettuce, limas, maruba santoh, okra, pak choy, peppers, radishes, Roma paste tomatoes, scallions, senposai, spinach, tatsoi, tokyo bekana, tomatoes, turnips and turnip greens, winter radishes, winter squash, yukina savoy, zucchini.  Could lightly harvest rhubarb before frost.

A busy fall week

Senposai, a delicious leafy green that grows fast and is fairly cold-hardy

This week has gone by in a flash. The weather has been conveniently dry, so we have been able to make progress on some of the weedy crops. We’ve uncovered turnips, senposai, kale, Chinese cabbage, Yukina Savoy, winter radishes, and a whole new sowing of beans that already have big fat beans on them! I noticed them a few days ago, but we ran out of time on Tuesday and didn’t harvest them.

The nights have been so chilly (one was 45F!) , and the mornings so dewy that it has been impossible to get everything harvested before lunch. So many of the crops at this time of year are best not touched while the leaves are wet, to minimize the spread of fungal diseases. Our crew only works in the mornings in summer, although some of us still have garden work during the rest of the day too. Today was our last morning shift, and tomorrow we start afternoon shifts, until next May. Not everyone relishes gardening in the afternoons, but it makes the most sense in terms of harvesting and also transplanting.

This year’s fall kale doesn’t look as good as this yet.

We had to resow all of our beets and some of our kale – I think they were eaten by baby grasshoppers or crickets. Possible because our lack of timely mowing around the edges of the plots this summer led to tall grass which is good habitat for grasshoppers. or possibly we over-watered in our effort not to under-water! The new kale is up and I’m keeping an eye on it in case it disappears. Some of our spinach seedlings have also disappeared, I fear. But there is still time to resow spinach. We reckon if we sow it before 9/20, we’ll get some to eat in late fall and during the winter. if we miss that date anmd sow 9/20-9/30, the plants will over-winter small, and we can start harvesting from them in the spring. Spinach makes some growth whenever the temperature rises above 40F in winter, and in our climate (and under the rowcover), it will get plenty of sunny days during the winter.

We started harvesting our broccoli last weekend – it’s over a week earlier than usual, this year. That’s good news, but it caught us hopping, because we are participating in the NOVIC variety trials, and need to record data each time we harvest. A comical event was that when I printed the rating sheet on our only color printer, it ran out of blue ink, and the broccoli colors came out in sunset shades! Luckily, I’d asked for some printed copies in the mail and those arrived later that day. Our color printer is in our Tofu office, and those who know our tofu know that blue features prominently in our tofu packaging and marketing – take a look at the webpage here. I guess that’s where the blue ink went!
