How to grow okra in Maine, step by step
- Start seeds indoors (Apr 2 – Apr 16). Sow seeds 1 inch deep in seed-starting mix under bright light. They take 7-14 days to sprout, fastest in soil around 85°F. Harden seedlings off for a week before they go outside.
- Prepare the bed. It needs at least six to eight hours of direct sun a day and loose soil at least 24 inches deep, with a pH between 6.0 and 7.5. Dig in compost before planting.
- Plant out (May 21 – Jun 7). Space plants about 15 inches apart in rows 36 inches apart. It is killed by frost, so nothing goes outside until the danger has passed.
- Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
- Watch for pests and problems. Pests: aphids, flea beetle, corn earworm, stink bug. Diseases and disorders: fusarium wilt, powdery mildew, root-knot nematode.
- Harvest (from about Jul 17 – Aug 1). Okra takes 50-65 days to reach harvest. Loves real heat and shrugs off drought once established. Soak seed overnight before sowing. Pick pods at 2-3 in every day or two or they turn woody and the plant slows.
