How to make food come out of the ground twelve months a year in central Arkansas (roughly USDA zone 8a), so a community fridge, hub, and cellar never go empty. Built on University of Arkansas Cooperative Extension planting data. Every date is a regional average — a guide, not a guarantee; always check the current forecast.
Climate baseline (Garland County / Hot Springs): USDA hardiness zone 8a; average last spring frost ~April 3, first fall frost ~October 31 (~211 frost-free days, NWS Little Rock, 1991–2020). Clark County (Arkadelphia) is effectively the same.
The point isn't a summer garden — it's a supply that never stops. That takes three habits most gardens skip: plant a fall garden in the heat of August, grow crops bred to store, and keep the cold-hardy greens going through winter under cover.
| Month | Plant & start | Harvest | Store & do |
|---|---|---|---|
| Jan | Garlic (last call, by mid-Jan); start onion seed | Kale, collards, spinach, carrots — under cover | Soil-test; order seed; build beds with compost |
| Feb | Irish potatoes (mid-Feb); onion sets; peas, spinach, lettuce, radish, carrots, beets, kale; broccoli/cabbage starts | Overwintered greens | Row cover for early sowings |
| Mar | More cool-season; start tomatoes & peppers indoors | Early greens, radish, spinach | Harden off transplants |
| Apr | After ~Apr 3 frost: beans, sweet corn, tomatoes; sweet-potato slips (Apr 20+) | Spring greens, lettuce, radish, green onions | Mulch beds; trellises |
| May | Okra, peppers, eggplant, cucumbers, squash, melons, lima beans | Peas, lettuce, strawberries, spring onions | Succession-sow beans & corn |
| Jun | Southern peas; successions of beans, squash, corn | Squash, cucumbers, dry onions, early tomatoes, new potatoes | Keep water steady |
| Jul | Fall starts: tomatoes (Jul 1–15), corn, southern peas, summer squash; fall potatoes (Jul 15+) | Garlic, tomatoes, peppers, squash, beans, melons | Cure garlic |
| Aug | The fall garden (Aug 1–Sep 15): carrots, collards, broccoli/cabbage/cauliflower, beets, chard, turnips, mustard; kale (20th+), spinach (25th+), lettuce | Summer peak | Start fall transplants |
| Sep | Finish fall greens & roots (through 15th); last spinach, lettuce, radish | Summer tail + first fall greens | Set low tunnels / row cover |
| Oct | Garlic (start); overwintering onions | Before frost: winter squash, sweet potatoes; fall greens ramping | Cure sweet potatoes & squash |
| Nov | Garlic (still fine); overwinter onions | Fall peak: kale, collards, spinach, carrots, beets, broccoli, cabbage | Onions & potatoes into the cellar; cover winter beds |
| Dec | Garlic (still fine) | Cold-hardy greens & roots under cover — sweeter after frost | Plan next year; turn compost |
Most gardens quit in October; the ones that feed a community don't. In zone 8a, kale, collards, spinach, mustard, and turnip greens keep producing through winter, garlic and overwintered onions hold in the ground until summer, and carrots and beets keep under mulch. A floating row cover buys about 2°F of protection (heavier fabric 6°F+); a low tunnel or cold frame buys more.
The season-extension move that's capital, not labor — a hoop house. A high tunnel turns three seasons into four, and the USDA NRCS Seasonal High Tunnel cost-share helps pay for the structure (a grant that buys ten years of growing — see the engine). Rules: pre-manufactured kit, ≤30 ft wide, ≥6 ft peak, ≤2,160 sq ft, grown in native soil; you front the cost and get reimbursed. Get the current Arkansas rate from your local NRCS office.
| Crop | Cure | Store at | Keeps |
|---|---|---|---|
| Sweet potatoes | 85°F, 90% humidity, 7–10 days | 55–60°F, 85–90% humidity | 6–8 months |
| Irish potatoes | 60°F, a few days, dark | 38–42°F, ~90% humidity | 6–8 months |
| Winter squash & pumpkins | harvest before hard frost | 55–60°F, dry | 2–6 months |
| Garlic | dry down, airflow | 72°F+, dry (not cold) | ~8 months |
| Onions | dry down | 32°F, 65–70% humidity | 6–7 months |
| Dry beans | dry fully; freeze 48h to kill weevils | cool, dry, in jars | 1 year+ |
Two habits worth the ink: don't store onions and potatoes together (each speeds the other's spoiling), and onions sprout in a fridge — keep them cold-cold or cool-dry, not in between.
