Harvest Tips
Peppers can be harvested at the glossy black stage (immature) or allowed to ripen to red for fuller flavor and higher heat. Use sharp pruning shears to cut peppers from the plant to avoid damaging branches. Harvest regularly to encourage continued production. In warm climates, plants often produce fruit continuously through fall.
