Harvest Tips
Pick peppers when fully mature and bright yellow for best flavor and visual appeal. Use sharp pruning shears to avoid damaging branches. Peppers can be harvested at green stage but develop full sweetness when yellow. Plant typically produces heavily for 2-3 months in warm climates before declining. In subtropical zones, may need to replant annually as a frost-sensitive annual crop.
