Germination
2-4 weeksSeeds sprout with two small cotyledons (seed leaves); slow germination is normal
Keep soil consistently warm (75-85°F) and moist but not waterlogged. Germination can take 2-4 weeks. Bottom heat improves success.
Seedling
4-6 weeksTrue leaves emerge; plants develop small, delicate foliage; slow growth rate
Provide bright light (grow lights help). Keep soil lightly moist. Maintain warm temperatures. Thin seedlings to strongest specimens.
Vegetative Growth
8-12 weeksPlant develops woody stems and bushy foliage; slow but steady branching occurs
Pinch growing tips to encourage bushiness. Provide bright light and warm conditions. Water moderately. Begin fertilizing with balanced fertilizer every 2-3 weeks.
Flowering & Fruiting
8-16 weeksSmall white or pale pink flowers appear; tiny green peppers develop and ripen to bright red (occasionally yellow or orange)
Maintain consistent warmth. Reduce nitrogen fertilizer; use high-potassium formula. Hand-pollinate flowers if grown indoors. Water regularly but allow brief dry periods.
Harvest & Maturity
Ongoing throughout growing seasonPeppers fully ripen to red; plant continues producing fruit; may bear for several years if properly maintained
Harvest mature peppers when fully red for maximum heat and flavor. Reduce watering slightly in winter dormancy. Can be pruned to maintain shape.

Harvest Tips
Pick peppers when fully red (or yellow/orange if that variety) for maximum heat and flavor. The longer peppers remain on the plant, the hotter they become. Peppers are extremely hot (50,000-100,000+ Scoville Heat Units), so handle carefully and wear gloves. Harvest regularly to encourage continued production. Can be dried for storage.
