Seedling
2-3 weeksTiny sprouted seeds with first true leaves appearing. Plant is 1-2 inches tall with delicate stems.
Keep soil consistently moist but not waterlogged. Maintain 70-80°F temperature. Provide bright light (grow lights 3-4 inches above seedlings). Thin seedlings to strongest plants if directly seeded.
Transplant/Early Growth
4-6 weeksYoung plants 4-8 inches tall with 4-6 true leaves and developing root system. Ready for outdoor planting after last frost.
Harden off transplants by gradually exposing to outdoor conditions over 7-10 days. Maintain consistent moisture and warm temperatures (65-75°F minimum). Begin light feeding with diluted balanced fertilizer.
Vegetative/Growth
3-4 weeksPlant establishes in garden, growing 12-24 inches tall with bushy foliage and branching structure forming. No flowers yet.
Maintain steady watering and full sun exposure. Apply 2-3 inches of mulch to retain moisture and regulate soil temperature. Prune lower branches if desired for air circulation. Begin weekly fertilizing with balanced fertilizer once established.
Flowering/Fruit Set
3-4 weeksSmall white flowers appear at leaf axils. Flowers bloom and pollinate (often self-pollinating), followed by tiny green fruit appearing.
Maintain consistent watering—do not allow drought stress during flowering, which can cause flower/fruit drop. Switch to higher-phosphorus fertilizer to support fruiting. Ensure full sun and good air circulation. Hand-pollinate flowers if bee activity is low by gently shaking plants mid-morning.
Fruiting/Harvest
4-8 weeks (or longer with continued production)Green peppers enlarge to 4-6 inches, turning darker green. Plants produce prolifically. Peppers gradually shift from green to red over 2-3 weeks.
Continue consistent watering and feeding every 7-10 days with fertilizer. Harvest green peppers to encourage continued production, or leave on plant for red maturity. Support heavy fruit branches with stakes if needed. Watch for pests and disease pressure.

Harvest Tips
Harvest peppers when they reach desired size—green peppers can be picked 60-75 days after transplanting for fresh use, or left on the plant for red maturity (75-90 days total). Cut peppers with pruning shears or a sharp knife, leaving a short stem attached. Early harvesting of green peppers encourages continued production. For maximum flavor and heat, allow peppers to fully ripen to red. Harvest in early morning when fruits are coolest. Regular harvesting prolongs the season and increases overall yield.
