Seedling
2-3 weeksTiny green cotyledons emerge, developing true leaves within 2-3 weeks. Plants are delicate and require consistent warmth and moisture.
Maintain soil temperature of 70-80°F. Provide bright light to prevent leggy growth. Use grow lights if needed. Keep humidity moderate to prevent damping off.
Vegetative
4-6 weeksPlant develops multiple leaf sets, branching structure becomes visible. Sturdy stems form with increasingly larger leaves. Plant grows 6-12 inches tall.
Thin seedlings to strongest specimens. Continue warm conditions. Gradually acclimate to outdoor conditions if transplanting. Begin fertilizing with diluted balanced fertilizer every 2 weeks.
Flowering
3-4 weeksSmall white flowers appear at leaf axils along branches. Flowers are delicate with pale petals and yellow stamens. Plant reaches mature height of 12-18 inches.
Maintain consistent watering and fertilization. Apply balanced or slightly higher phosphorus fertilizer to encourage fruit set. Ensure adequate light and warmth for pollination. Hand-pollinate or allow insects to pollinate.
Fruiting
4-6 weeks to first maturitySmall, upright white peppers develop from flower sites, initially pale green then turning creamy white at maturity. Peppers are typically 2-3 inches long. Plant becomes very ornamental at this stage.
Maintain steady watering; avoid drought stress. Continue regular fertilization every 2-3 weeks. Provide stakes or cages if needed for support under heavy fruit load. Protect from extreme heat stress with shade cloth if necessary.
Harvest/Production
8-12 weeks or until frostContinuous production of white peppers throughout growing season. Plant remains productive for 2-3 months in optimal conditions. Peppers can be harvested at white stage or left to develop deeper flavor.
Harvest regularly to encourage continued flowering. Remove any diseased or damaged fruit immediately. Maintain consistent fertilization and watering. Deadhead spent flowers to redirect energy to ripening fruit.
