Growth Stages

1

Seedling

2-3 weeks

Tiny plants with first true leaves emerging; very delicate

Maintain 70-80°F soil temperature; keep under grow lights 12-14 hours daily; maintain consistent moisture without waterlogging; thin crowded seedlings

2

Vegetative

4-6 weeks

Compact plant develops multiple stems and small, narrow leaves; plant grows 2-4 inches tall

Provide bright light; maintain warm temperatures (65-75°F); fertilize every 2-3 weeks with balanced fertilizer; pinch growing tips if needed to encourage bushiness

3

Flowering

3-4 weeks

Small white or pale purple flowers appear at leaf nodes; multiple flower clusters form

Ensure adequate pollination by gently shaking plant or using a small brush; maintain consistent watering; apply low-nitrogen, high-phosphorus fertilizer to encourage fruiting

4

Fruiting

4-6 weeks

Upright green peppers develop at flower sites, typically 1-2 inches long; fruits gradually fill out and mature

Continue regular watering; maintain warm temperatures; support heavy fruit clusters with small stakes if needed; maintain fertilizer schedule for continuous production

5

Maturation & Harvest

Ongoing (4-8 weeks per fruiting cycle)

Peppers transition from green to red (optional); plant may continue producing additional flowers and fruits

Harvest at green stage for mild flavor or allow ripening to red for sweeter, hotter peppers; remove harvested fruits to encourage new growth; continue watering and fertilizing

Harvest Tips

Peppers can be harvested at green stage (75-90 days after flowering) for milder flavor or allowed to fully ripen to red (10-14 additional days) for increased heat and sweetness. Use sharp scissors or pruners to cut peppers cleanly from the plant to avoid damaging branches. Regular harvesting encourages continued production throughout the growing season.
