Seedling
3-4 weeksTiny seedlings with first true leaves emerging; fragile and light green in color.
Provide bright light for 14-16 hours daily under grow lights. Keep soil moist but not soggy. Maintain warmth (70-75°F). Begin fertilizing weekly with half-strength balanced fertilizer once true leaves appear.
Vegetative Growth
4-6 weeks after transplantingPlant develops multiple stems and darker green leaves. Bushy, compact growth habit typical of Oklahoma White variety.
Harden off before transplanting outdoors. Space 18 inches apart. Pinch out early flower buds to encourage branching. Maintain consistent moisture and provide balanced fertilizer every 2-3 weeks.
Flowering
3-4 weeks (overlapping with fruiting)Small white to pale yellow flowers appear at branch terminals. Flowers are self-fertile.
Ensure adequate water and nutrients to support fruit set. Pollinate manually with a small brush if indoors or in poor pollinator conditions. Continue balanced fertilization.
Fruiting
4-6 weeks per fruit setSmall green peppers emerge and elongate over time. Peppers gradually transition from green to white as they mature.
Switch to higher phosphorus/potassium fertilizer to boost fruiting (e.g., 5-10-10). Maintain consistent watering without overwatering. Provide support stakes if plants become heavily laden.
Mature Harvest
Until frost (in cool zones) or indefinitely in warm zonesPeppers reach full white color and size (typically 3-4 inches long). Plant may continue producing peppers throughout the season.
Harvest ripe peppers regularly to encourage continued production. Use sharp scissors or pruners to avoid damaging branches. Continue watering and fertilizing for subsequent flushes of flowers and fruit.

Harvest Tips
Harvest peppers when they turn fully white for best flavor and ornamental appearance. This typically occurs 70-90 days after transplanting. Use sharp pruning shears or scissors to cut peppers at the stem, avoiding damage to branches. Peppers can be harvested at any stage of maturity (green to white), but white peppers are mildest and most prized. Regular harvesting encourages continued fruit production throughout the season. In cooler zones, harvest all remaining fruit before the first frost.
