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).
Watch the forecast and if frost is expected that night
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.
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.
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.
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.
