During the Month:

Lettuce Factory: Sow heat-resistant lettuce outdoors, every 8 to 6 days, #10, 11, 12, 13, 14. Transplant 120/week (1/3 bed). #7, 8, 9, 10, 11 this month.

Deal with potato beetles with Spinosad [or Neem] once larvae are seen, if >50 adults/50 plants or >200 larvae/100 plants. Spinosad: Spray when bees not flying (early morning or late evening.) Shake well, 1-4 Tbsp/gall. Expect to need 1.5-2 hours and 9-10.5 galls. Clean and triple rinse the sprayer. Do not flush in creek or pond. Repeat if needed in 6-7 days – could spot spray where larvae are seen. Flame weed potatoes before 12” high, if needed.

Deal with asparagus beetles, if necessary. See notes under April.

Early May:

Continue cutting sweet potato slips until we have enough.

Transplant when hardened off: celery, celeriac, lettuce #7, main tomatoes (2’).

Set out drip tape & bioplastic mulch , transplant Romas (2’),  peppers (18” when soil 70°F, dogwood blooms dropping), hot peppers, and melons #1, sweet potatoes

Sow peanuts (120d), asparagus beans in bed w/ celery, okra, sunflowers. limas #1, cow peas #1 (68d)

Roll out driptape and bioplastic mulch for watermelons.

Cover Crops: Sorghum-Sudan, soy, buckwheat, or pearl millet as summer cover crops, now frost is past.

Mid-month:

Plant sweet potatoes, 16″ apart, with 4-4.5′ between ridges, 5’ at edges of patch. Install drip irrigation on ridges and plant at every other emitter. Ideal if soil temp is 65°F for four consecutive days before planting.  If weather dry, dip roots in mud slurry before planting.  Plant 2-3” deep, with at least 2 nodes in ground, and at least 2 leaves above ground.  If slips are long, plant horizontally to increase production.

Transplant lettuce #8, eggplant (2’ apart, single row in center of bed, spray off flea beetles with jet of water & cover immediately), watermelon, insectaries, (okra if not direct-sown – mulch later, when soil warm).

Set out drip tape and biodegradable mulch and transplant melons and watermelons at four weeks old max. Cover for 3 weeks. Move rowcover off broccoli (12 pieces) and strawberries (~8 pieces) Watermelon needs 12 pieces.

In greenhouse sow tomatoes #3, filler watermelons & Romas. Sow cukes & squash #2 if spring is late and cold, and direct-sowing not wise.

Sow beans #2 (5/14, 28 days after #1), edamame #2, carrots #6, sunflowers.

Till between rows of corn #1 & transplant in gaps and/or thin to 8”.

Weed onions 3 weeks before expected harvest date, and broccoli.

Garlic: Harvest garlic scapes, remove mulch from garlic, and weed.  Move mulch to weeded broccoli.

Check maturity of potato onions and garlic. Likely harvest order is fall potato onions 5/25-6/10, hardneck garlic 5/30-6/15, spring potato onions 6/3-6/18, bulb onions 6/11-6/30, softneck garlic 6/5-6/15.

#4 Spring Tractor Work mid-May – Disk areas for June potatoes, corn 3,4,5, & later succession plantings of beans, squash, cucumbers.

Late May:

Mow between no-till paste tomato rows before mulching with hay. Fill gaps, weed, tuck mulch.  Set up posts and string weave the tomatoes, using thick baler twine for lower 3 rows. Really try to keep up with weekly string-weaving.

String weave 1 row around peppers, using short stakes.

Clear empty coldframe and mulch with cardboard or plant something.

Till each corn twice, undersowing at 2nd tilling (30 days), when 12” high, with soy for #1-5, oats/soy for #6. Thin corn to 8”. Avoid cultivating corn after it’s knee-high—roots are shallow.

Sow corn #2, cowpeas #2; cukes #2 (picklers and slicers), summer squash & zukes #2 5/24 (or in greenhouse 5/14, transplant 6/7), watermelons #3, winter squash 5/26 (put woodash with seeds to deter squash vine borer). If squash sowing is late, don’t sow Tahitian butternut – slow.  Cover cucurbits (perhaps not winter squash) against cucumber beetles. Max. cuke beetle population is mid-May; keep susceptible plants well-covered until flowering.

Transplant lettuce #9, 10, 11; Roma paste tomato replacements for casualties, insectary flowers. Fill gaps in eggplant, peppers, melons, watermelons.

Store any seeds not needed until fall or next spring, in basement (radishes, onions, winter squash, watermelon).

Harvest fall planted Potato Onions in dry weather, after tops have fallen, (5/25-6/10, spring planted 6/3-18).  May not all be ready at once. Handle gently. Dry as clusters in barn on wooden racks for 1-2 months, using fans. Service fans or buy new as needed. Eat potato onions >2.5” without curing, unless yield is very low, in which case label & refrigerate, then plant in September. Weight after drying for 1 week is approximately twice the final weight. First sorting is late June. Use the Worksheet and Log Book

Harvest garlic when 6th leaf down is starting to brown on 50% of the crop (ie .5 green leaves, so that 5 skins cover cloves), or cut open horizontally- when air space is visible between. stem and cloves it’s time to harvest.  [Could replant small cloves immediately for garlic scallions.] Allow 15 mins/bucket harvesting and 15 mins/bucket for hanging in netting in barn,.

Till garlic area, sow soy & buckwheat to control weeds until fall carrot planting.

Plan fall and winter crops for raised beds.

Cover crops: can sow buckwheat, soy, millet, and sorghum-sudan during May.

Perennials: Put up blueberry netting before fruit sets. Weed & water & top up mulch. Mow grape & fall raspberry aisles. New grapevines: remove side branches and fruitlets. Weekly: visit grapes and log progress 4/20-5/30. If asparagus weeds are getting out of hand, mow down one or more rows to keep control.

Early March:

1st March: chit seed potatoes in flats for 2-4 weeks with bright light in basement.

Check irrigation and hoses. Buy replacements as needed.

Buy twine: make up to 6 binder and 2 baler twine.

Inventory cover crop seeds, buy buckwheat, sorghum-sudan, pearl millet, clover or other summer cover crops.

Compost needed in March: 6-9 tractor buckets for beds, 8-20 to disk in.

Compost and till raised beds for April plantings – carrots #4 & 5, lettuce 4-6, beans #1.

Mid-March:

Cut seed potatoes and heal for three days: two buds on each piece, one for insurance.  Ginger too.

Plant potatoes when the weather becomes suitable (when daffodils bloom.). Reduce sprouts/piece to 2. See Perfect Potato  Planting card.

In greenhouse: sow main crop tomatoes, lettuce #5 [sesame]. Protect cabbage and broccoli at 5-8 true leaves from cold stress (<40°F for a few days, or longer at 50°F).
