Vegetative
4-6 weeksBushy growth with multiple branches; leaves dark green and fully formed; no flowers yet
Maintain warm temperatures (70-80°F). Fertilize every 2-3 weeks with balanced fertilizer (10-10-10). Ensure consistent moisture. Pinch growing tips to encourage bushiness.
Flowering
3-4 weeksSmall white or pale yellow flowers appear at leaf axils; plant reaches full height
Switch to lower-nitrogen fertilizer (5-10-10) to encourage flowering. Maintain consistent watering. Ensure good air circulation. Hand pollinate if growing indoors by gently shaking flowers.
Fruiting
30-50 daysSmall green peppers develop and grow; gradually change from green to yellow-orange as they mature
Reduce nitrogen; use higher potassium fertilizer (10-20-20). Water consistently but allow slight drying between waterings. Support heavy branches with stakes or cages. Mulch to regulate soil temperature.
Harvest Ready

Harvest Tips
Harvest when peppers reach full yellow color for optimal fruity flavor, typically 3-4 months after planting. Use clean scissors or pruners to cut peppers at the stem, leaving some plant material to prevent damage. Harvest regularly (every 3-5 days) to encourage continuous production. Peppers can also be harvested green if needed, though flavor is less developed. Store ripe peppers in cool conditions; they keep 2-3 weeks refrigerated.
