Growth Stages

1

Seedling

3-4 weeks

Small seedlings with 2-4 true leaves; delicate appearance

Start seeds indoors 8-10 weeks before last frost; maintain 70-80°F soil temperature; provide bright light to prevent leggy growth; keep soil consistently moist but not waterlogged

2

Vegetative

4-6 weeks

Compact bushy plants with well-developed foliage, 12-18 inches tall, no flowers yet

Harden off seedlings gradually before transplanting outdoors; space 18 inches apart; apply mulch (2-3 inches) to retain moisture and regulate temperature; side-dress with balanced fertilizer every 3-4 weeks

3

Flowering

2-3 weeks

Small white flowers appear in leaf axils; plant continues growing in height

Maintain consistent watering and soil moisture; avoid over-fertilizing nitrogen, which can delay flowering; provide support stakes as plant grows; hand-pollinate flowers if bee activity is low by gently shaking plants midday

4

Fruiting

3-4 weeks

Green peppers develop and enlarge; plant may reach 24-30 inches tall; peppers transition to red as they mature

Continue consistent watering; reduce nitrogen fertilizer and increase potassium and phosphorus; support heavy branches with stakes or cages; pick immature peppers to encourage continued flowering

5

Harvest

Ongoing through frost

Peppers reach full maturity at 6-8 inches long; color shifts from green to deep red when fully ripe

Harvest peppers when still green for milder flavor or allow to fully ripen for maximum heat and sweetness; use pruning shears to avoid damaging branches; continue harvesting to promote more fruit production

Harvest Tips

Pick peppers when they reach 6-8 inches long using pruning shears or a sharp knife; harvest at any stage—green peppers are milder, while fully red peppers have maximum heat and sweetness; regular harvesting encourages more fruit production; for drying, allow peppers to fully mature and dry on the plant or harvest and hang to cure indoors

Fun Facts
