Harvest Tips
Peppers can be harvested when black and glossy (firm, slightly spicy) or left to mature to red (sweeter, slightly milder). Use sharp pruners or scissors to cut peppers cleanly from the stem. Regular harvesting (2-3 times per week) encourages continuous production. In warm climates, plants can produce for many months; in cooler zones, harvest before first frost and bring plant indoors if potted.
