How to grow bell peppers in Vermont, step by step
- Start seeds indoors (Mar 12 – Mar 26). Sow seeds ¼ inch deep in seed-starting mix under bright light. They take 7-14 days to sprout, fastest in soil around 82°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 (May 21 – Jun 7). Space plants about 18 inches apart in rows 30 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, tomato hornworm. Diseases and disorders: bacterial leaf spot, anthracnose, blossom-end rot (calcium disorder), phytophthora blight.
- Harvest (from about Jul 27 – Aug 26). Bell Pepper takes 60-90 days to reach harvest. Needs warm soil; wait until nights stay above 55 F to transplant. Green peppers are just unripe coloured peppers left another 2-3 weeks.
