Seed Germination & Seedling
7-14 days germination; 4-6 weeks to transplant sizeSeeds sprout with first true leaves appearing. Seedlings develop 2-4 inches tall with characteristic oval pepper leaves.
Keep soil warm (75-85°F) and consistently moist. Provide 14-16 hours of grow light indoors. Transplant to individual pots once first true leaves emerge.
Vegetative Growth
3-4 weeks after transplantingBushy, compact plants with dense foliage reach 12-18 inches tall. Stems thicken and branch structure develops.
Harden off seedlings gradually before planting outdoors. Plant after last frost when soil reaches 60°F. Provide consistent warmth, sunlight, and balanced fertilizer. Pinch early flower buds to encourage branching.
Flowering
3-4 weeksSmall white or pale yellow flowers appear at branch nodes in clusters. Plants become increasingly ornamental.
Maintain consistent watering and sunlight. Reduce nitrogen to encourage flowering. Support branches if heavy with fruit development. Allow flowers to pollinate naturally via wind or pollinators.
Fruiting & Color Change
4-6 weeksSmall tapered peppers develop and elongate to 2-4 inches. Peppers transition from green to deep red as they mature.
Continue consistent watering and feeding with balanced or slightly higher potassium fertilizer. Stake or support branches if needed. Maintain full sunlight for color development. Peppers can be harvested green or left to fully ripen to red.
Peak Production & Harvest
6-10 weeks or until frostMature plants produce multiple clusters of fully red peppers. Plants may become heavily laden with fruit.
Harvest peppers regularly to encourage continued production. Prune dead or diseased foliage. Continue regular watering and feeding. Plants can produce until first frost in cool climates.

Harvest Tips
Peppers can be harvested green at 2-3 inches long for a mild, fresh flavor, or left on the plant to fully ripen to deep red (7-10 more days) for maximum heat and sweetness. Use clean scissors or pruners to cut peppers from the plant rather than pulling. Regular harvesting encourages continued production throughout the season. For drying, harvest fully mature red peppers and hang in a warm, dry, well-ventilated space until completely dry.
