Seedling
4-6 weeks indoorsSmall plants with 2-4 true leaves, compact growth. Seedlings are tender and require warmth.
Maintain soil temperature of 70-80°F. Provide bright light (14-16 hours daily) to prevent leggy growth. Keep soil consistently moist but not waterlogged.
Vegetative
3-4 weeks after transplanting outdoorsRapid stem and leaf growth; plants develop a branching structure. No flowers yet. Height reaches 12-18 inches.
Acclimate seedlings gradually to outdoor conditions before transplanting. After transplanting, water regularly and apply mulch. Begin light feeding with balanced fertilizer every 2-3 weeks.
Flowering
3-4 weeksSmall white flowers appear at branch nodes. Flowers are self-fertile and attractive to pollinators.
Maintain consistent watering; drought stress can cause flower drop. Switch to a higher phosphorus/potassium fertilizer to encourage fruiting. Ensure good air circulation.
Fruiting
6-8 weeks as peppers mature and colorSmall green peppers form at flower sites, gradually enlarging and turning red. Plants remain highly productive with new flowers forming continuously.
Continue consistent watering and feeding. Remove any diseased or misshapen fruits. Provide support stakes if needed for heavy fruit load. Maintain mulch to regulate soil temperature.
Harvest
Continues until frost or plant declinePeppers reach full red color (fully mature) or can be harvested green. Mature red peppers have maximum heat and sweetness.
Harvest peppers regularly to encourage continued flowering and fruiting. Use clean pruners to avoid damaging the plant. Continue harvesting until first frost in cooler zones.

Harvest Tips
Peppers can be harvested green (younger, milder) or left on the plant to fully ripen to bright red (hotter, sweeter flavor). Red peppers are fully mature and have peak heat levels. Use clean pruning shears to cut peppers rather than pulling, which can damage the plant. Regular harvesting encourages more fruit production. Plants will continue producing until frost in warm climates or until brought indoors.
