How to grow bell peppers in New Jersey, step by step
- Start seeds indoors (Feb 16 – Mar 2). 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.

- Plant out (Apr 27 – May 14). 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.
