Germination
7-14 daysSeeds sprout with tiny cotyledons emerging. Seedlings are fragile and pale green.
Maintain 70-80°F soil temperature. Use grow lights if indoors. Keep soil moist but not soggy. Sow indoors 8-10 weeks before last frost.
Seedling
3-4 weeksFirst true leaves develop; plant grows slowly and remains compact. Seedlings are vulnerable to damping-off.
Provide 14-16 hours of grow light daily. Maintain 70-75°F. Begin gentle air circulation with a fan. Thin to strongest seedlings if needed.
Vegetative
3-4 weeks after transplantingPlant develops multiple stems and increasingly dense foliage. Growth accelerates after transplanting outdoors.
Transplant after last frost when soil is warm. Pinch growing tip early to encourage bushiness. Water consistently. Apply balanced fertilizer every 2-3 weeks.
Flowering
3-6 weeksSmall white or pale purple flowers appear along branches. Flowers are delicate and short-lived.
Continue consistent watering and feeding. Flowers may drop if temperatures exceed 90°F or fall below 60°F. Provide afternoon shade in extreme heat. Light fertilizer with lower nitrogen promotes more flowers.
Fruiting
4-8 weeks until harvest-readySmall green peppers form at flower sites and gradually enlarge. Peppers progressively turn from green to bright crimson red.
Maintain consistent moisture—irregular watering causes blossom-end rot and fruit cracking. Reduce nitrogen fertilizer; apply phosphorus and potassium. Support heavy branches with stakes if needed. Peppers take 2-3 weeks to mature from green to red.

Harvest Tips
Peppers can be harvested green or left on the plant to turn brilliant red (red peppers are sweeter and riper). Use sharp scissors or pruning shears to cut peppers, leaving small stems attached. Harvest regularly to encourage more flowering. Ripe peppers are firm and glossy. In warm climates, plants can produce throughout the season.
