When to Plant Peppers

Bell pepper seedlings

Plant pepper seedlings in the garden 2 to 3 weeks after the last frost in spring. Start pepper seeds indoors 8 to 10 weeks before setting transplants in the garden. Don’t set out pepper seedlings until the average night temperatures are 55°F (13°C).

You can set pepper seedlings in the garden earlier if they are protected from the cold by a plastic tunnel or other season-extending devices.

Sweet peppers mature in 60 to 70 days. Sweet peppers can be harvested and used before they mature, or they can be left on the plant until they reach full size and ripen to a deep red color. Hot peppers are ready any time they are usable size.

Peppers grow best in sandy loam that is well-drained and fortified with a lot of organic matter such as aged compost. Plant peppers in full sun. Keep the soil evenly moist from flowering through harvest.

Peppers can share space with cabbage and onions. Carrots are a companion that is said to enhance the growth of peppers.
