Seedling
2-3 weeksSmall plants with 2-4 true leaves, delicate and tender
Provide warm soil (70-80°F), bright light, and consistent moisture. Keep humidity moderate to prevent damping-off disease. Begin gentle air circulation with a fan.
Vegetative
4-6 weeksBushy growth with multiple stems, increasing leaf size and branching
Maintain warm temperatures (75-85°F daytime). Provide full sun exposure. Apply balanced fertilizer every 2-3 weeks. Pinch growing tips to encourage bushier growth if desired.
Flowering
3-4 weeksSmall white flowers with yellow centers appear at branch tips; flowers drop and set fruit
Ensure consistent watering and humidity (not soggy); temperature fluctuations cause flower drop. Maintain full sun. Switch to phosphorus-rich fertilizer to promote fruiting.
Fruiting
4-6 weeksSmall green peppers develop and elongate; gradually turn red as they mature
Maintain consistent deep watering, especially during fruit expansion. Fertilize every 2 weeks with balanced or slightly higher potassium formula. Support heavy fruit clusters with stakes if needed.
Harvest
Ongoing, 4-8 weeks or until frostPeppers reach full red color and desired size; mature peppers are firm and glossy
Pick peppers with 0.5 inches of stem attached. Green peppers are edible but lack full heat; wait for red maturation for optimal flavor. Continue harvesting to encourage more production.

Harvest Tips
Begin harvesting when peppers reach full red color (approximately 75-90 days from transplant). Use scissors or sharp knife to cut peppers with 0.5 inches of stem rather than pulling. Peppers can be harvested green for less heat or left to mature fully for more intense heat and complex flavor. Continue harvesting throughout the season to encourage continuous production. Morning harvest yields fresher peppers.
