Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge; small leaves appear. Plant is very fragile and tender.

Provide bright light 12-16 hours daily under grow lights. Keep soil consistently moist but not waterlogged. Maintain temperature at 70-80°F. Provide gentle air circulation.

2

Vegetative

4-6 weeks

True leaves develop; plant grows bushy with sturdy stems. Leaves are dark green and increasingly robust.

Gradually expose to outdoor conditions if starting indoors (hardening off). Maintain warm temperatures (70-85°F). Water when top inch of soil is dry. Begin light fertilization every 2-3 weeks with balanced fertilizer.

3

Flowering

3-4 weeks

Small white flowers appear in leaf axils. Plant becomes increasingly compact and bushy.

Switch to slightly lower-nitrogen, higher-phosphorus fertilizer to encourage fruiting. Maintain consistent watering. Ensure adequate sunlight (8+ hours). Gentle hand-pollination or air movement aids fruit set.

4

Fruiting

4-6 weeks

Green peppers develop from flower bases and grow to 3-4 inches long. Plant becomes heavy with fruit.

Maintain consistent watering (critical during this stage). Provide stakes or cages for support if needed. Continue regular fertilization every 2-3 weeks. Remove first few flowers to encourage larger fruit.

5

Harvest

Continuous for 4-8 weeks or until frost

Peppers reach full size and firm texture. Can harvest green or allow to turn red over 2-3 weeks.

Pick peppers when firm and fully developed green color. Regular harvesting promotes continued production. Use pruners or scissors to avoid damaging branches.

Harvest Tips

Peppers can be harvested when they reach full size at the mature green stage (3-4 inches long), typically 60-90 days after transplanting. For red peppers, leave fruit on the plant for an additional 2-3 weeks after reaching green maturity. Harvest in the morning when peppers are firm. Use pruners to avoid damaging the plant. Regular harvesting encourages continued production throughout the season. In containers, expect 20-30+ peppers per plant depending on conditions.

Fun Facts

  • 🌱 Green Boy is specifically bred for container growing and was developed to produce full-sized peppers on dwarf plants, making it perfect for apartment gardeners and limited spaces.
  • 🌱 Green peppers are actually immature red peppers—if left on the plant for 2-3 additional weeks, Green Boy peppers will turn red and develop a sweeter flavor and higher vitamin C content.
  • 🌱 Bell peppers are actually berries botanically, containing multiple seeds in a hollow cavity, and a single Green Boy plant can produce 20-30+ peppers in a growing season when given consistent care.
