Growth Stages

1

Seedling

3-4 weeks

Tiny plants with 2-4 true leaves emerging from seed coat.

Keep soil moist but not waterlogged. Provide 14-16 hours of bright light daily. Maintain 70-80°F. Thin to strongest seedling if overcrowded.

2

Vegetative

4-6 weeks

Bushy growth with multiple stems, lobed leaves, and increasing plant height (12-18 inches typical).

Maintain consistent warmth (70-85°F). Water regularly. Begin fertilizing with balanced NPK. Pinch early flowers if more vegetative growth is desired.

3

Flowering

3-4 weeks

Small white to pale flowers appear in leaf axils and branch tips; plant reaches near-mature height.

Switch to slightly lower nitrogen fertilizer to favor fruiting. Maintain even moisture. Provide pollinator access or gently shake plants. Ensure adequate potassium and phosphorus.

4

Fruiting

4-6 weeks per flush (multiple flushes possible)

Long, slender peppers emerge and elongate; they ripen from green to bright red over several weeks.

Continue consistent watering and balanced feeding. Support heavy fruit loads with stakes or cages if needed. Monitor for pests. Harvest green peppers or allow to mature red.

5

Harvest & Maturity

Until frost or season's end

Plant produces sustained yields of full-size red peppers; slowing growth in cool weather signals season's end.

Harvest ripe red peppers regularly to encourage continued production. In frost-prone areas, pick remaining fruit before frost and ripen indoors. Can be overwintered indoors in containers.

Common Pests

  • Spray with water to dislodge; use neem oil or insecticidal soap; increase humidity; release predatory mites if severe.

  • Spray with strong water stream; apply insecticidal soap or neem oil; attract beneficial insects (ladybugs, lacewings).

  • Remove affected leaves; use blue sticky traps; spray with neem oil or spinosad; maintain good air circulation.

  • Use yellow sticky traps; spray undersides of leaves with insecticidal soap or neem oil; encourage natural predators.

  • Remove and destroy infested fruit; use pheromone traps; apply spinosad if available; rotate crops.

  • Avoid overhead watering; remove infected leaves; use copper fungicide; ensure good air circulation; rotate crops.

Harvest Tips

Harvest peppers green (after about 7-8 weeks from flowering) or allow to fully ripen to bright red (2-3 additional weeks). Use sharp pruning shears or scissors to avoid damaging branches. Pick regularly to stimulate continued flowering and fruiting. Aci Red peppers are excellent dried whole or ground into powder; hang-dry in a warm, airy location for 3-4 weeks.
