Seedling
3-4 weeksSmall leafy growth with cotyledons, then true leaves emerging. Plant is fragile and compact.
Provide 14-16 hours of grow light daily indoors. Keep soil consistently moist but not waterlogged. Maintain 70-80°F for germination and growth.
Vegetative
4-6 weeks after transplantingRapid growth of stems and leaves. Plant becomes bushier. No flowers yet. Stem thickening and branching occurs.
Harden off before transplanting outdoors. Transplant when 2-3 inches tall. Water consistently. Apply balanced fertilizer every 2-3 weeks. Pinch growing tips if desired to encourage bushiness.
Flowering
3-4 weeks, then continuous floweringSmall white or pale purple flowers appear at leaf axils throughout the plant canopy.
Continue consistent watering and balanced feeding. Ensure adequate sunlight and pollinator access (or hand-pollinate if indoors). Avoid excessive nitrogen which promotes foliage over flowers.
Fruiting
4-6 weeks from fruit set to maturitySmall round peppers develop from flowers, initially green, gradually enlarging to marble-sized fruits. Peppers mature to deep red over time.
Maintain consistent watering; fluctuations cause blossom-end rot or fruit cracking. Switch to slightly higher phosphorus fertilizer to support fruiting. Support heavy-laden branches if needed.
Harvest & Maturity
Continuous until frost or end of seasonPeppers reach full size (0.75-1 inch diameter) and turn bright red. Plant continues producing throughout season in warm climates.
Harvest regularly to encourage continued production. Pick when peppers are firm and fully colored. Can be harvested green for pickling or left to mature for sweet, spicy flavor.

Harvest Tips
Harvest peppers when firm and full-sized. For pickling, pick when green to light green (0.75-1 inch diameter). For fresh eating, allow to mature to bright red for maximum sweetness (about 1 week after green stage). Harvest regularly to promote continued flowering and fruit production. Use clean scissors or knife to avoid damaging stems. Morning harvests preserve the best quality.
