Harvest Tips
Harvest green peppers any time after they reach full size (2-3 inches long) by cutting with scissors or pruning shears. For red peppers, allow 2-3 weeks after fruit reaches full size for color development. Harvesting green peppers encourages more flowering and fruit production. Plants typically produce 20-30+ peppers per season in good conditions.
