Seedling
2-3 weeksTiny seedlings with first true leaves emerging; still fragile with cotyledons visible.
Provide bottom heat (70-80°F) and bright light indoors. Keep soil consistently moist but not waterlogged. Thin seedlings if crowded.
Vegetative
4-6 weeksPlant develops bushy foliage with multiple sets of true leaves; no flowers yet; transplant size (4-6 inches tall).
Harden off seedlings before transplanting outdoors. Plant after last frost when soil is warm (60°F+). Provide support stakes as plant grows.
Flowering
3-4 weeksSmall white flowers with yellow centers appear in leaf axils; plant reaches 18-24 inches tall.
Maintain consistent watering and temperatures above 60°F. Pollinate flowers by hand or allow bee activity. Ensure adequate phosphorus for flower development.
Fruiting
3-4 weeksSmall green peppers develop from flowers, gradually lengthening to 6-8 inches; plant becomes heavily laden.
Increase watering as fruits develop. Apply mulch to retain moisture and regulate soil temperature. Support heavy branches with stakes or cages.
Harvest & Maturation
6-10 weeks (ongoing until first frost)Peppers ripen from green to bright red; plant continues producing new flowers and fruits throughout season.
Pick peppers at green or red stage depending on use. Continue regular watering and feeding. In late season, stop new flower pinching to allow final fruits to mature.

Harvest Tips
Pick peppers at green stage (2-3 months) for immediate use in fresh applications, or allow to fully ripen to red (3-4 months) for sweeter flavor and higher capsaicinoid content. Use sharp shears to avoid damaging the plant. For drying, harvest red peppers and hang in warm, dry location (80-90°F) for 2-3 weeks. NM Cayenne can produce continuously until first frost.
