Seedling
3-4 weeksSmall plants with 2-4 true leaves; tender and delicate with pale green coloring
Keep soil warm (70-80°F), maintain consistent moisture, provide bright light 14-16 hours daily. Use grow lights if indoors. Begin fertilizing with dilute liquid fertilizer every 2 weeks.
Vegetative Growth
4-6 weeksPlants develop multiple branches and deeper green foliage; no flowers yet. Stems thicken and become woody.
Transplant outdoors after last frost when soil is warm. Provide consistent warmth (70-85°F). Water regularly and fertilize every 2-3 weeks with balanced fertilizer. Pinch off early flower buds to encourage branching.
Flowering
3-4 weeksSmall white or pale purple flowers appear at leaf axils; plant is bushy and full. Flowers are self-pollinating but benefit from insect or hand pollination.
Maintain warm temperatures and consistent watering. Switch to lower-nitrogen fertilizer (higher phosphorus and potassium). Shake plants gently in morning to aid pollination. Keep soil consistently moist.
Fruiting & Maturation
6-8 weeksSmall wrinkled green peppers form and gradually enlarge; eventually turn bright red. Multiple peppers develop on each branch throughout the season.
Continue consistent watering and weekly fertilizing. Support heavy fruit with stakes or cages if needed. Prune lower leaves for air circulation to prevent disease. Harvest green peppers anytime, or allow to fully ripen to red for maximum heat and flavor.
Harvest & Extended Production
Ongoing until frostRipe red peppers ready for picking; plants continue producing new flowers and peppers in warm climates
Harvest regularly to encourage continued production. Use pruners to cut peppers rather than tearing branches. Continue weekly fertilizing and consistent watering. In frost-prone areas, harvest all peppers before first frost.

Harvest Tips
Peppers can be harvested green (slightly hotter, more herbaceous flavor) or allowed to ripen to deep red (sweeter, more complex heat). Cut peppers with pruners rather than pulling to avoid damaging branches. Harvest regularly to promote continued production. In cooler climates, pick green peppers before first frost.
