Germination & Seedling
10-14 days germination; 4-6 weeks to transplant-readySeeds sprout and develop first true leaves. Plant is small with delicate foliage.
Start seeds indoors 8-10 weeks before last frost. Maintain soil temperature 70-80°F. Provide bright light to prevent leggy growth. Keep soil consistently moist but not soggy.
Vegetative Growth
4-6 weeksPlant develops sturdy stems and bushy foliage. Multiple branches form with alternating leaf pairs.
Transplant after last frost when nighttime temps stay above 55°F. Harden off gradually over 7-10 days. Apply balanced fertilizer every 2-3 weeks. Pinch center stems when 6-8 inches tall to encourage bushiness.
Flowering
3-5 weeksSmall white to pale yellow flowers appear at branch tips. Plant reaches 12-18 inches tall and becomes increasingly bushy.
Continue consistent watering and fertilizing. Switch to lower-nitrogen, higher-phosphorus fertilizer (5-10-10) to support flowering. Ensure adequate sunlight. Pollinate flowers by gently shaking plant or using a small brush.
Fruiting & Maturation
4-8 weeks per fruit cycle; 2-3 cycles possible in one seasonGreen peppers develop and enlarge at flower sites. Pods remain upright. Color gradually shifts from green to bright red over 2-3 weeks.
Maintain consistent water schedule; fluctuating moisture causes blossom-end rot and cracks. Fertilize every 3-4 weeks with balanced or potassium-rich formula. Mulch around base to retain moisture and regulate temperature. Support heavy fruit clusters if needed.
Harvest & Continued Production
Throughout growing season until frostMature red peppers are harvestable. Plant continues flowering and producing new fruit until frost.
Harvest red peppers by cutting at stem base rather than pulling to avoid plant damage. Remove green peppers near end of season to redirect energy to ripening remaining fruit. Bring potted plants indoors before frost to extend season.

Harvest Tips
Harvest peppers when they turn bright red for maximum heat and flavor (typically 60-90 days after flowering). Peppers can also be eaten at green stage for milder flavor. Cut peppers at the stem with sharp scissors or pruners rather than pulling to avoid damaging the plant. Regular harvesting encourages continued production. One plant can produce 50-100+ peppers in a season.
