Seedling
2-3 weeksTiny seedlings with first true leaves emerging, very delicate with thin stems
Maintain soil moisture without waterlogging. Provide bright light (grow lights if indoors). Keep temperatures at 70-80°F. Thin to strongest seedling if multiple seeds sprouted together.
Vegetative Growth
3-5 weeksPlant develops multiple sets of leaves, growing bushy and compact. Stems thicken and branching increases. No flowers yet.
Harden off transplants gradually before moving outdoors. Plant outdoors after last frost when soil reaches 60°F. Space 18-24 inches apart. Water consistently and begin weekly fertilizing with balanced fertilizer once established.
Flowering
2-4 weeksSmall white or pale flowers appear at branch tips and axils. Flowers are typically solitary or in small clusters.
Ensure consistent watering and maintain temperatures above 60°F (flowers may drop if too cold). Continue regular fertilizing, switching to lower-nitrogen formula. Ensure adequate sunlight for pollination. Provide support stakes if needed.
Fruiting
3-4 weeks to harvest maturityPeppers develop and enlarge, starting as small white buds and growing to 2-3 inch elongated fruits. Color remains white/cream initially, may yellow slightly when fully mature.
Continue consistent watering—critical during fruit development. Maintain fertilizing schedule. Remove any damaged fruits. Provide support cages or stakes to prevent branch breakage from pepper weight.
Harvest & Extended Production
6-12 weeks depending on climatePeppers reach mature size and desired color. Plant continues producing new flowers and developing additional peppers throughout growing season.
Harvest peppers regularly to encourage continued production. Use sharp knife or pruners to avoid damaging plant. Continue watering and fertilizing. In frost-free zones, plant can produce into winter.

Harvest Tips
Harvest peppers when they reach mature size and desired firmness, typically 60-90 days after transplanting. Pick peppers when white or cream-colored (they may yellow slightly more if left longer, but harvest is not dependent on color change like red peppers). Use a sharp knife or pruners to cut peppers from the plant, leaving a short stem. Harvest regularly to encourage continued flowering and fruiting. Can be harvested at any maturity stage from green to cream, though white/cream fruit is most distinctive.
