When to plant chili peppers in Hawaii
Hawaii is essentially frost-free (USDA zones 9b, 10a, 10b, 11a, 11b, 12a, 12b, 13a), so chili pepper timing there is set by heat and daylength rather than frost. As a warm-season crop, the main risk is mid-summer heat — spring and late-summer plantings usually do best.
Hawaii covers a wide range of climates, so your exact frost dates may differ from the state average by two weeks or more. For dates tuned to your town, use the calendar generator.

How to grow chili peppers in Hawaii, step by step
- Start seeds indoors (Nov 30 – Dec 14). Sow seeds ¼ inch deep in seed-starting mix under bright light. They take 7-21 days to sprout, fastest in soil around 85°F. Harden seedlings off for a week before they go outside.
- Prepare the bed. They need at least six to eight hours of direct sun a day and loose soil at least 12 inches deep, with a pH between 5.5 and 7.0. Dig in compost before planting.
- Plant out (Feb 8 – Feb 25). Space plants about 18 inches apart in rows 24 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, pepper maggot, spider mite. Diseases and disorders: bacterial leaf spot, anthracnose, phytophthora blight.
- Harvest (from about Apr 26 – May 26). Chili Pepper takes 70-100 days to reach harvest. Superhots (C. chinense) can need 100+ days and the longest indoor start. Withholding some water late raises heat.
