Harvest Tips
Pick peppers when full-sized and glossy. Green peppers can be harvested anytime, but allowing them to ripen to red, yellow, or orange takes 2-3 weeks longer and increases sweetness and vitamin C. Use pruners or sharp knife to avoid damaging the plant. Harvesting encourages continued production. Regular picking can yield 8-10 peppers per plant over the season.
