Growing directions
Sow seeds 1/4 inch deep in warm starting mix; peppers germinate best when soil stays above 75°F. Harden off transplants over 7–10 days before planting, and wait until soil temperature reaches at least 65°F. Keep moisture consistent to prevent fruit drop, and apply a balanced fertilizer once flowering begins. Pick green for mild flavor or leave on the plant to ripen to red, yellow, or orange for maximum sweetness.
