Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with two cotyledons emerge, followed by true leaves. Plants are delicate and light green.

Keep soil moist but not waterlogged. Provide bright light, 12-16 hours daily under grow lights. Maintain temperature of 70-75°F.

2

Vegetative Growth

4-6 weeks

Plant develops multiple stems and dark green compound leaves. Bushy structure forms with increasing branching.

Thin seedlings or transplant when 2-3 inches tall. Maintain warm temperatures (65-75°F). Fertilize every 2-3 weeks with diluted balanced fertilizer. Can pinch growing tips to encourage bushiness.

3

Flowering

3-4 weeks

Small white flowers with yellow centers appear at branch tips, typically arranged in clusters. Buds may drop if stressed.

Ensure consistent watering and warmth (70-85°F optimal). Avoid temperature fluctuations below 60°F. Continue regular feeding with balanced or slightly phosphorus-rich fertilizer. Hand-pollinate if growing indoors by gently shaking flowers.

4

Fruiting

4-6 weeks per color stage

Small peppers develop and point upward. Fruits progress through color changes: bright yellow, then orange, then deep red at full maturity. Multiple flushes of fruit develop.

Maintain consistent watering. Switch to slightly higher potassium fertilizer (e.g., 5-10-10) to support fruit development. Remove diseased or damaged fruits. Provide support stakes if plant becomes heavily laden.

5

Harvest

Ongoing through season

Mature peppers are firm, glossy, and have reached full desired color. Plants may continue producing new flowers and fruit.

Harvest regularly to encourage continued production. Use sharp scissors or pruners to avoid damaging stems. Harvest peppers at any color stage for use; fully red peppers are sweetest.

Harvest Tips

Harvest peppers when they reach desired color and feel firm. For maximum pungency, allow to ripen to red. Peppers can be picked at yellow or orange stage and will continue ripening off the plant. Regular harvesting encourages continued production. Use sharp pruners to avoid damaging branches. Store fresh peppers in refrigerator for up to 2 weeks, or dry for long-term storage.
