Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with cotyledons (seed leaves), followed by first true leaves. Plants are delicate and light green.

Keep soil warm (70-80°F) and consistently moist. Provide bright light, 14-16 hours daily if indoors. Avoid overwatering to prevent damping off.

2

Vegetative Growth

3-4 weeks

Plant develops 4-6 true leaves and establishes a compact, bushy form. Stems thicken and foliage becomes darker green.

Transplant into larger containers if starting indoors. Begin hardening off 7-10 days before outdoor planting. Pinch growing tip if plant becomes leggy to encourage bushiness.

3

Flowering

3-4 weeks

Small white or pale purple flowers appear in leaf axils along the stems. Flowers are self-pollinating but benefit from air movement.

Maintain consistent watering and avoid temperature fluctuations. Provide air circulation to aid pollination. Feed with balanced or slightly phosphorus-rich fertilizer every 2-3 weeks.

4

Fruit Development

3-4 weeks

Small green peppers form at flower sites and gradually enlarge. The compact plant becomes laden with upright-pointing fruit.

Continue consistent watering. Apply mulch to retain moisture and regulate soil temperature. Support plant if branches bend under fruit weight.

5

Maturation & Harvest

Continuous until frost

Peppers ripen from green to bright red. Plant continues to flower and produce new fruit throughout the season.

Harvest peppers at red stage for best flavor and ornamental appeal. Continued harvesting encourages more fruit production. Maintain regular watering and feeding through frost.

Harvest Tips

Harvest peppers when they turn bright red for optimal sweetness and flavor, typically 60-90 days after transplanting. Use pruning shears or a sharp knife to avoid damaging the plant.

Plants are prolific and will produce throughout the season until frost.
