How to grow chili peppers in Louisiana, step by step
- Start seeds indoors (Jan 1 – Jan 15). 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 (Mar 12 – Mar 29). 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 May 28 – Jun 27). 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.
