Seedling
3-4 weeksSmall plants with 2-4 true leaves, tender and delicate
Maintain 70-75°F soil temperature. Provide bright light 14-16 hours daily. Keep soil consistently moist but not waterlogged. Avoid damping off by ensuring good air circulation.
Vegetative Growth
3-4 weeksRapid stem and leaf development; compact bushy growth habit with multiple side shoots
Harden off seedlings 7-10 days before transplanting. Plant after last frost when soil is warm. Pinch top if height exceeds container capacity. Apply balanced fertilizer every 2-3 weeks.
Flowering
2-3 weeksYellow flowers appear in clusters along the main stem and branches
Ensure consistent watering to prevent blossom end rot. Provide stakes or cages for support. Reduce nitrogen fertilizer; increase phosphorus and potassium to encourage fruit set.
Fruiting
3-4 weeksSmall green fruits develop rapidly in characteristic clusters; fruits gradually enlarge and ripen to red
Maintain consistent soil moisture to prevent cracking and blossom end rot. Remove lower leaves once fruits set to improve air circulation. Deadhead suckers if desired.
Harvest
4-8 weeks until frostFruits turn deep red and become slightly soft to gentle pressure
Pick fruits at full red color for best flavor, or harvest at breaker stage and ripen indoors. Continue harvesting regularly to encourage more production. Enjoy abundant yield until first frost.
