Seedling
2-3 weeksTiny seedlings with first true leaves emerging; plant is 1-2 inches tall with delicate foliage
Keep soil consistently moist but not waterlogged. Provide bright light (14-16 hours under grow lights). Maintain temperature 70-80°F. Thin seedlings if overcrowded.
Vegetative Growth
3-4 weeksBushy plant developing 3-4 sets of true leaves; plant reaches 4-8 inches with increasing branching; compact, rounded habit forming
Gradually acclimate to outdoor light if growing indoors. Fertilize with balanced fertilizer (10-10-10) every 2 weeks. Maintain warm temperatures (65-75°F minimum). Keep soil consistently moist.
Flowering
2-3 weeksSmall white flowers with yellow centers appear in clusters along branch tips; plant is 10-14 inches tall and dense
Shift to higher phosphorus fertilizer (5-20-20) to encourage fruiting. Ensure adequate light and consistent moisture. Gently shake plant when flowers open to aid pollination, or use a small brush. Maintain warmth (70-80°F during day).
Fruiting
3-4 weeksSmall peppers (1-2 inches long) develop at branch tips, progressing from green to scarlet red; plant may have multiple fruits at various stages
Continue regular watering and balanced fertilization. Peppers may benefit from light staking if heavily laden. Remove oldest foliage if crowded to improve air circulation. Maintain consistent warmth.
Mature/Harvest
Until frost or 2-3 months+Peppers fully color to deep scarlet red; plant reaches full compact size (12-18 inches); heavily productive with continuous flowering
