Seedling
2-3 weeksTiny plants with 2 cotyledons (seed leaves) emerge; first true leaves appear small and serrated
Keep soil consistently moist but not waterlogged; provide 14-16 hours of grow light 2-3 inches above seedlings; maintain 65-75°F
Vegetative Growth
3-4 weeksPlant develops 6-8 true leaves and establishes strong root system; stems thicken and foliage becomes dense
Harden off seedlings by gradually exposing to outdoor conditions over 7-10 days; transplant when 6-8 inches tall with 6-8 true leaves; stake or support early
Flowering
3-4 weeksYellow flowers appear in clusters; plant reaches full size for determinate type; vigorous leafy growth continues
Provide consistent watering and maintain nutrient balance; lightly fertilize weekly with balanced or slightly higher phosphorus formula; ensure good air circulation; avoid excessive nitrogen which promotes leaves over fruit
Fruiting & Maturation
4-6 weeksSmall green fruits develop and rapidly enlarge; fruits transition from green to blush to full red color over 20-30 days per fruit
Maintain consistent soil moisture (critical to prevent cracking and blossom-end rot); continue fertilizing every 2 weeks; prune suckers on determinate types only if needed for air flow; monitor for pests and diseases
Harvest
2-4 weeks ongoingFruits reach full red color, slightly soft when gently squeezed; plant may slow production in high heat
Pick at full color for best flavor; harvest regularly to encourage continued production; remove any diseased fruit immediately
