Seedling
2-3 weeksTiny leaves emerge; plant is 1-3 inches tall with initial true leaves developing
Keep soil consistently moist but not soggy. Provide bright light (12-16 hours under grow lights). Maintain temperature of 70-75°F. Thin seedlings if crowded.
Vegetative Growth
4-6 weeksPlant develops multiple stems and larger leaves; 4-10 inches tall with bushy appearance
Harden off seedlings by gradually exposing to outdoor conditions over 7-10 days before transplanting. Maintain warm temperatures (65-75°F). Begin dilute fertilizing at half-strength once true leaves appear.
Establishment & Growth
3-4 weeksPlant reaches 12-18 inches tall post-transplant; strong root system and multiple branch points visible
Water deeply and consistently. Provide support stakes if needed. Apply balanced fertilizer (14-14-14) weekly or slow-release fertilizer monthly. Mulch around base to retain moisture and regulate soil temperature.
Flowering
2-4 weeksSmall white or cream-colored flowers appear at branch nodes; plant continues expanding
Maintain consistent watering. Ensure temperatures are 70-85°F; below 55°F or above 95°F causes flower drop. Switch to lower-nitrogen fertilizer (5-10-10) to encourage fruit set. Do not overwater.
Fruiting & Harvest
5-8 weeksGreen peppers develop and swell; turn bright yellow when fully mature. Multiple fruits per plant typical
Continue consistent watering; mulch maintains moisture. Continue fertilizing every 2-3 weeks. Harvest green peppers or allow to ripen to yellow. Pinch off flower buds 6-8 weeks before first frost to redirect energy to ripening existing fruit.

Harvest Tips
Peppers can be harvested green or allowed to mature to bright yellow for sweeter flavor (7-10 additional days). Cut peppers with sharp pruners rather than pulling to avoid damaging branches. Yellow peppers are fully ripe when deeply colored and slightly soft to gentle pressure. Harvest regularly to encourage more fruit production. Each plant can produce 15-30+ peppers depending on conditions.
