Twin Oaks August Garden Calendar


Here’s the list of what we plan to do in our garden this month. We’re in central Virginia. Our average first frost is October 14

 During the month:

Lettuce Factory: Sow lettuce every 5 to 3 days. Switch to cold-tolerant varieties after 20th. Transplant sowings #22, 23, 24, 25, 26.Set out 120 plants every 6-5 days (1/3 bed). Store seed in fridge.

Sort potatoes 2 weeks after storing. Ventilate root cellar every few nights when coolest. Gradually get temperature down to 65°F by the end of the month. Try not to have temperature reversals.

String weave tomatoes once a week until plants reach top of posts.

Onions: move from basement to walk-in cooler as soon as space allows.

Monitor for grasshoppers on brassicas, carrots, beets.

Prevent nutsedge tuber formation by weekly cultivation in Aug and Sept.

Seed saving: Roma tomatoes – select plants, based on yield and septoria resistance. Mark & harvest seeds (usually 1 bucket each time) on days before bulk harvests. Don’t use diseased fruit or fruit from plants in decline. Keep 4-5 days till dead ripe, scoop seeds on Food Processing shift days. Ferment at 70°F for 3 days. Stir 3x/day. Wash, dry. Eg: Harvest Mon, scoop Friday, wash and dry Monday. Save 4 buckets tomatoes for 130gm seed.

Crimson Sweet Watermelon Seed: Overmature 10 days, harvest, scoop seeds, ferment 4 days at 70°F. Stir 3x/day. Wash, dry. Eg: Harvest and scoop Tuesday, wash Saturday. 1 melon = 22 g seed. 22 melons = 1 lb seed.

Perennials: Make new strawberry beds: Compost, till, raise, drip tape, newspaper and hay mulch. Chip or sawdust paths. One new patch follows corn #3, other follows part of the Green Fallow area. Plantnew strawberries using plugs, rooted potted runners or plants carefully thinned from last year’s beds. Water strawberry plants for next year’s crop, weed, and give compost. Mow aisles for fall raspberries, grapes. Remove blueberry roof netting if not done in July. Mow, weed, water in general. Grapes:visit, log progress, tie in, once in early August, once in late August.

Cover crops: Sow spring oats and soy for winter-killed cover in empty beds. (Not rye – may head up before winter.) Can sow buckwheat, soy, sorghum sudan, clovers; possibly winter barley, Miami peas; or Lana woolypod vetch at 2-3 oz /100 sq. ft. with oats

Early Aug:

Sow beans #6 (8/3, 15 days after #5), cukes #5 (slicing, by 8/5, latest) & zucchini and summer squash #5 (by 8/9), winter & fall radishes, turnips (by 8/15 if possible, by 9/15 latest), Swiss chard, 6 beds kale (2 each on 8/4, 8/10, 8/16, 8/24 until enough is established. Use rowcover against fleabeetles), beets (can sow dry or presoak 12 hours; sow 1/2″-1″ deep, tamp soil, keep damp, use shadecloth?). Sow all the fall carrots if not sown in late July & flame weed. Sow fall brassicas. Consider sowing sunflowers in kale beds to encourage grasshopper-predator birds.

Put spinach seeds in freezer now, two weeks before sowing, to improve germination .

Till between rows of corn #5, undersow with soy.

Transplant lettuce #22, 23. Finish transplanting all brassicas. Hoe and wheel-hoe the brassica patch, one section each morning. Re-cover or take covers from earlier plantings.

Water sweet potatoes when vines fully extended, (critical period for water).

Potato Onions, third sorting 8/5-10: check through, snip tops, separate clusters, sort by size, and weigh or estimate yield. Save 6 racks (150#) large (2-2½”), 5 racks (100#) medium (1½-2”), 4 racks (80#) small (<1½”) per 360 row foot bed wanted. Sell spare.

Plan and map next year’s main garden so best cover crops can be planted. Order winter cover crop seed.

Mid Aug: DON’T sow carrots or kale w/o cover (grasshoppers).

Till or wheel-hoe between broccoli rows (uncover), and undersow with mammoth red clover, white clover and crimson clover mix. Till between rows of corn #6 and undersow with oats & soy

Transplant lettuce #24

Sow kale #2, 3 (2 beds each time), fall radishes #2. Thin rutabagas to 10”, by 4 weeks-old.

Order seeds if needed: winter lettuce, early cabbage, other salads, kale, spinach, beets, onions, peppers, hoophouse tomatoes, winter hoophouse greens.

Late Aug: Sow kale as needed, scallions #5.

Finish fall carrot sowing if unable to get it done by early August – Flame weed.

Really finish transplanting brassicas, including kale from #1 beds. Transplant lettuce #25, 26

1st Fall disking: Disk corn #1 (future garlic), maybe form beds, sow buckwheat, soy (and Sorghum Sudan?) Disk corn #2 patch, sow oats & soy (future spring broccoli & cabbage). Or sow corn #1&2 in oats & soy and make garlic beds in October.

Disk old spring broccoli (may be already in summer cover crops), in time to sow rye and vetch 9/7.

August Harvests: Asian melons, asparagus beans, beans, cantaloupes, carrots, celery, chard, corn, cow peas, crabapples, cukes, edamame, eggplant, grapes (early or late Aug), komatsuna, lettuce, limas, maruba santoh, okra, pak choy, peppers, hot peppers, fall raspberries, Romas, senposai,  summer squash, Tokyo bekana, tomatoes, turnip thinnings, watermelons, winter squash (acorn & cha cha ), yukina savoy, zucchini.
