When to plant

Plant outdoors after frost danger passes and the soil has warmed. In short-season areas, count back from your intended outdoor planting date for indoor starts. South Florida outdoor window: August–February.

How to plant

1. Prepare loose, well-drained soil or a clean seed-starting mix. Start indoors about 8 weeks before transplanting; slow hot peppers may need longer.
2. Sow ¼ inch deep. Keep the seedbed evenly moist until seedlings emerge. Then water when the soil needs it, allowing excess water to drain.
3. Thin or transplant to the listed final spacing. Give seedlings sufficient light and check moisture as roots establish.

How to harvest

Pick full-sized green fruit or allow the variety’s ripe color to develop. Use care when handling hot peppers.

Aunt E’s tip: Label sweet and hot seedlings separately before the trays all look alike.
