Seedling
2-3 weeksTiny plants with 2-4 true leaves emerge; stems are delicate and pale green
Maintain warm soil (70-80°F), provide bright light 14-16 hours daily, keep soil consistently moist but not waterlogged, thin seedlings if overcrowded
Vegetative Growth
4-6 weeksCompact bushy plant develops multiple branches with dark green lance-shaped leaves; no flowers yet
Harden off transplants gradually before outdoor planting, maintain steady warmth (70-80°F minimum), provide balanced fertilizer every 2-3 weeks, pinch off early flower buds to encourage branching if desired
Flowering
3-4 weeksSmall white or pale purple flowers appear in leaf axils; plant becomes dense and heavily budded
Ensure consistent watering and warmth; avoid nitrogen-heavy fertilizers which reduce flowering, provide support if needed as fruit becomes heavy, mulch around base
Fruiting & Development
3-4 weeksPeppers develop from flowers, initially green and finger-like, gradually enlarging to 3-4 inches long
Continue regular watering and fertilizing with balanced or slightly higher potassium formula, support heavily fruiting branches, remove some lower leaves for air circulation if humid
Maturation & Harvest
8-12 weeks (continues until frost)Peppers transition from green to brilliant red; plant may produce continuously until frost
Harvest green peppers anytime for mild heat, or wait for full red color for maximum heat and sweetness, remove mature fruits to encourage continued production, monitor for pests and disease

Harvest Tips
Peppers can be harvested at any stage; green peppers are ready 60-70 days after flowering and have mild heat. Wait 75-90 days for full red maturity to develop peak heat (70,000-80,000 Scoville Heat Units typical for cayenne). Cut peppers with scissors or pruners leaving 1 inch of stem. Regular harvesting encourages more fruit production. Inferno Cayenne is particularly prized for drying whole or grinding into cayenne powder; peppers can be left on the plant to dry before harvesting, or harvested fresh and dried indoors in bundles.
