Growth Stages

1

Seedling

4-6 weeks

Tiny plants with 2-4 true leaves, slow initial growth

Keep soil warm (75-85°F), provide bright indirect light, maintain consistent moisture. Start seeds indoors 8-10 weeks before last frost.

2

Vegetative

6-8 weeks

Plant develops sturdy stem and multiple branches, grows 12-24 inches tall

Provide full sun, fertilize every 2 weeks with balanced fertilizer, pinch off early flowers to encourage branching. Harden off transplants before outdoor planting.

3

Flowering

4-6 weeks

Small white flowers appear in clusters at branch tips

Maintain consistent watering and full sun. Switch to higher phosphorus fertilizer to promote fruit set. Ensure temperatures stay between 70-85°F for best pollination.

4

Fruiting

4-6 weeks

Green peppers develop, grow upright on the plant, gradually enlarge

Reduce nitrogen fertilizer, increase potassium and phosphorus. Water deeply but allow soil to dry slightly between waterings. Support heavy fruit clusters if needed.

5

Maturation & Harvest

Ongoing through frost

Peppers transition from green to bright red, reach maximum heat and flavor

Continue regular watering and feeding. Pick peppers at full red color for maximum Scoville heat. Plant can continue producing through fall in warm climates.

Harvest Tips

Pick peppers when fully red for maximum heat (395,000-577,000 SHU) and flavor. Wear gloves to prevent skin irritation from capsaicinoids. Peppers can be harvested green, but waiting for red color increases potency. Cut peppers with pruners rather than pulling to avoid damaging the plant. Plants will continue producing until first frost in warm climates.
