Growth Stages

1

Seedling

Small sprouted plants with 2-4 true leaves, delicate and tender

Keep soil warm (70-80°F), provide bright light, maintain high humidity, protect from drafts

2

Vegetative

4-6 weeks

Plant develops multiple stems and leaves, growing bushy and compact; no flowers yet

Provide full sun, pinch off early flower buds to encourage branching, fertilize with balanced fertilizer every 2 weeks

3

Flowering

4-8 weeks

Small white or pale flowers appear at branch tips; plant continues growing taller and wider

Maintain consistent watering, switch to higher phosphorus fertilizer, ensure adequate sunlight for pollination, gently shake flowers to aid pollination

4

Fruiting

6-10 weeks

Small green peppers develop at flower sites, gradually enlarging and turning from green to red over time

Continue regular watering and fertilizing, provide support if needed, maintain temperatures 70-85°F, reduce nitrogen fertilizer to avoid excessive foliage at expense of fruit

5

Harvest

Ongoing until frost or end of season

Peppers reach full size and display vibrant red color; plant may continue producing new flowers and fruit

Harvest Tips

Harvest peppers when fully red and glossy for best flavor and heat development; this typically occurs 4-6 weeks after flowering. Cut peppers with pruners rather than pulling to avoid damaging the plant. Green peppers can be harvested early if desired for milder flavor. Regular harvesting encourages continued production throughout the season
