Seedling
3-4 weeksTiny seedlings emerge with cotyledons; first true leaves appear within 1-2 weeks. Plants are delicate and pale green.
Keep soil consistently moist but not waterlogged. Provide bright light (grow lights 3-4 inches above seedlings). Maintain temperatures 70-80°F. Thin if overcrowded.
Vegetative Growth
4-6 weeksPlants develop multiple sets of true leaves and establish a branching structure. Stems thicken and become woody. Plant reaches 12-18 inches tall.
Harden off seedlings gradually before transplanting. Once in ground, water deeply and mulch 2-3 inches. Provide support cages or stakes early. Apply balanced fertilizer every 2-3 weeks.
Flowering
3-4 weeksSmall white or pale yellow flowers appear in leaf axils. Flowers typically appear in clusters and are self-fertile.
Ensure consistent watering during flowering to prevent flower drop. Reduce nitrogen fertilizer; switch to higher phosphorus/potassium ratio to encourage fruit set. Provide support for developing branches.
Fruiting
4-6 weeksGreen peppers form and begin expanding. Peppers are thick-walled and elongated, gradually increasing in size. Plants become heavy with fruit.
Maintain consistent watering (critical at this stage). Continue balanced fertilization. Prune some leaves if peppers become shaded to improve air circulation and ripening.
Maturity & Harvest
Until frost or plant senescencePeppers mature from dark green to deep red when fully ripe. Fruits reach 5-7 inches long with thick, meaty walls. Plant may produce until frost.
Harvest at green stage for fresh use or allow to fully ripen on the plant. Continue watering and harvesting to encourage additional production.

Harvest Tips
Peppers can be harvested green (at 5-7 inches) for fresh eating and cooking, or left on the plant to mature to red (approximately 2-3 weeks more). For roasting and drying, the traditional use, allow peppers to fully ripen to deep red. Cut peppers with pruners rather than pulling to avoid damaging the plant. Peak harvest typically occurs 2-3 months after transplanting, with continued production until frost or plant decline. For drying, hang whole peppers in a warm, dry location or use a food dehydrator.
