When to Plant Peppers
Timing guide for seeds and transplants
Quick Answer
Transplant peppers outdoors 2-3 weeks after your last frost date when soil temperature is at least 65°F. Start seeds indoors 8-10 weeks before your planned transplant date. Peppers need warm conditions - rushing them into cold soil stunts growth.

Frequently Asked Questions
When should I start pepper seeds indoors?
Start pepper seeds indoors 8-10 weeks before your last frost date. Peppers are slow to germinate (7-14 days) and grow slowly as seedlings, so they need this head start. Use heat mats to maintain 80-85°F soil temperature for best germination.
What temperature do peppers need to be transplanted?
Wait until nighttime temperatures stay consistently above 55°F and soil temperature is at least 65°F. Peppers are tropical and cold soil stunts their growth. Cold nights can cause blossom drop and slow fruit development.
Can I plant peppers directly in the ground from seed?
It's possible in zones 9-11 with long growing seasons, but not recommended elsewhere. Peppers need 60-90 days to fruit, so most gardeners start indoors. Direct-sown peppers often don't mature before fall frost.
When is it too late to plant peppers?
Count backward from your first fall frost - peppers need 60-90 days to produce. If you're less than 70 days from frost, it's getting late. In short seasons, choose early varieties (60 days) or grow in containers you can move indoors.
