Vegetative Growth
4-6 weeksPlant develops multiple sets of true leaves, forms sturdy stems, and establishes root system. Reaches 6-12 inches tall before flowering begins.
Gradually acclimate seedlings to outdoor conditions over 7-10 days before transplanting. Transplant to larger pots when 2-3 inches tall. Maintain warm temperatures (70-80°F) and provide consistent moisture.

Ensure 8+ hours of direct sunlight daily. Begin fertilizing weekly with balanced fertilizer (14-14-14) or switch to lower nitrogen formula (5-10-10) to promote flowering. Maintain warm temperatures above 60°F at night.
Fruiting
4-6 weeks per flushSmall green peppers develop after flowers fade. Peppers gradually enlarge and begin color transition from green to yellow, orange, then red as they mature.
Continue consistent watering and fertilize every 2 weeks. Provide afternoon shade in extreme heat (above 95°F) to prevent sunscald. Support branches if heavily laden with fruit using stakes or cages.
Harvest
