Seedling
2-3 weeksTiny seed leaves emerge, followed by first true leaves. Plant is very delicate and requires consistent warmth and moisture.
Keep soil moist but not waterlogged. Provide 16+ hours of bright light daily. Maintain 70-80°F temperature. Thin seedlings to strongest individual if multiple sprout from same cell.
Vegetative Growth
4-6 weeksPlant develops multiple stems and leaves, creating a bushy, compact form. Internodes are short and growth is vigorous. No flowers yet.
Gradually acclimate to outdoor conditions if direct sowing. Provide consistent warmth (70-85°F). Fertilize bi-weekly with balanced fertilizer. Pinch main stem if needed to encourage bushiness.
Flowering
3-4 weeks (overlapping with fruiting)Small white or pale yellow flowers appear in clusters at leaf axils. Flowers are self-fertile but benefit from pollination.
Maintain consistent watering and nutrients. Ensure adequate air circulation and pollinator access or gently shake plants midday to aid pollination. Avoid excessive nitrogen which delays fruiting.
Fruiting & Development
6-8 weeksFlowers set fruit; small green peppers develop and elongate. Plant becomes laden with peppers at various stages of maturity.
Continue consistent watering and fertilizing. Provide support if needed. Thin overcrowded fruits if desired for larger individual peppers. Maintain calcium intake to prevent blossom end rot.
Ripening & Harvest
Until frost (continuous harvest season)Peppers transition from green to bright red. Fruits reach optimal sweetness and flavor when fully colored.
Harvest mature red peppers regularly to encourage continued production. Can harvest at any stage from light green to fully red depending on desired flavor intensity.

Harvest Tips
Harvest peppers when they reach full size and desired color, typically when fully red for maximum sweetness (about 80-90 days from planting). Use scissors or pruners to cleanly cut peppers from the plant, leaving stems intact. Harvest regularly to encourage continued fruiting throughout the season. Peppers can be harvested at green stage for slightly different flavor, though red stage is preferred for sweetness.
