Harvest Tips
Begin harvesting when peppers reach desired size and color. Yellow peppers are ready in 60-75 days from transplant; allow additional time for orange and red coloration if preferred. Harvest regularly (every 2-3 days during peak season) to encourage continuous production. Use sharp pruners or scissors to cut peppers, leaving a short stem attached. Peppers can be harvested at any color stage; green (immature) peppers are hottest, while fully red peppers develop more sweetness.
