Harvest Tips
Harvest peppers at purple stage (50-60 days post-flowering) for ornamental appeal, or allow to fully ripen to red for sweeter flavor (70-80 days). Use clean pruning shears or scissors to cut peppers 1-2 inches from the stem to avoid plant damage. Regular harvesting encourages continued flowering and fruiting. Peppers keep 1-2 weeks at room temperature or 3-4 weeks refrigerated
