How to grow okra in Montana, step by step

  1. Start seeds indoors (Apr 3 – Apr 17). 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.
  2. 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.
  3. Plant out (May 22 – Jun 8). 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.
  4. Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
  5. Watch for pests and problems. Pests: aphids, flea beetle, corn earworm, stink bug. Diseases and disorders: fusarium wilt, powdery mildew, root-knot nematode.
  6. Harvest (from about Jul 18 – Aug 2). 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.
