Growth Stages

1

Seedling

6-8 weeks

Small plants with 2-4 true leaves, 2-3 inches tall, developing root system

Keep soil consistently moist but not waterlogged. Provide bright light 14-16 hours daily. Maintain temperatures 70-75°F. Harden off gradually before transplanting outdoors.

2

Vegetative Growth

3-4 weeks

Young transplants establishing in garden, developing stronger stems and more foliage, 6-12 inches tall

Water regularly and deeply. Mulch around base to retain moisture and regulate soil temperature. Consider light staking for support. Monitor for pests weekly.

3

Flowering

3-4 weeks

Plant reaches 18-24 inches tall with profuse flower buds and small white flowers appearing throughout the plant

Maintain consistent watering; fluctuating moisture causes flower drop. Apply balanced fertilizer or bloom-promoting fertilizer every 2 weeks. Provide adequate air circulation. Hand-pollinate flowers if bee activity is low by gently shaking branches at midday.

4

Fruiting and Growth

4-6 weeks

Small green peppers develop from flowers, rapidly enlarging. Plant continues flowering while earlier fruits mature. Peppers grow to full size (4-5 inches long, blocky shape)

Continue consistent watering and fertilizing every 2-3 weeks. Support heavy fruits with small stakes or cages if needed. Pinch off some flowers if plant appears overloaded to encourage larger fruits. Prune lower leaves for air circulation.

5

Maturation and Harvest

Until first frost or end of season

Peppers reach full size; green peppers can be harvested at this stage or left to ripen to red, yellow, or orange depending on variety characteristics

Continue watering and light fertilizing. Harvest regularly to encourage more fruit production. Support branches with heavy fruit to prevent breakage. In fall, protect from early frosts with row covers if needed.

Harvest Tips

Pritchard's Giant peppers can be harvested green when full-sized (typically 3-4 weeks after flowering) or left on the plant to mature to red or yellow. For maximum sweetness and nutrient content, allow to fully ripen to color. Cut peppers with a short stem using pruning shears rather than pulling to avoid damaging the plant. Harvest regularly to encourage continued production throughout the season.
