Seedling
6-8 weeksSmall, delicate plants with 2-4 true leaves develop 6-8 weeks before last frost
Keep soil consistently moist but not waterlogged. Provide 14-16 hours of bright light daily. Maintain temps 70-80°F. Thin to one plant per cell.
Vegetative Growth
3-4 weeks after transplantPlants grow rapidly, developing more leaves and branching structure. Reaches 12-18 inches tall before flowering begins.
Harden off for 7-10 days before transplanting outdoors. Pinch growing tips to encourage bushiness. Apply balanced fertilizer every 2-3 weeks.
Flowering
2-3 weeksSmall white flowers appear at leaf nodes; flowers are delicate and self-fertile
Maintain consistent watering and warm temps (70-85°F). Ensure good air circulation. Do not overwater. Light fertilizer with higher phosphorus (5-10-10) aids flower set.
Fruit Development
4-6 weeksGreen peppers form and enlarge at flowering nodes. Peppers gradually change from green to deep purple-black as they mature.
Water consistently to prevent blossom-end rot. Support heavy fruit with stakes or cages. Mulch heavily. Provide consistent nutrition with balanced fertilizer every 3 weeks.
Harvest
Ongoing through frostPeppers reach full dark purple-black color and firm texture. Can harvest at green stage or wait for full color maturation.
Harvest using pruners or scissors to avoid breaking branches. Picking peppers encourages continued production. Store at 50-60°F. Ripe peppers are sweeter.

Harvest Tips
Begin harvesting when peppers are fully sized; they are sweeter and have richer flavor at full dark purple-black maturity (90+ days from transplant). Harvest regularly to encourage additional fruit production. Cut peppers with pruners rather than pulling to avoid branch damage. Morning harvest yields crispest peppers. Ripe Phantom peppers keep 2-3 weeks in cool storage (50-60°F).
Fun Facts
- 🌱 Phantom peppers get their dark purple-black color from anthocyanins, the same pigments found in blueberries, providing powerful antioxidants.
- 🌱 Bell peppers are actually berries botanically, not vegetables, and the 'heat' compound capsaicin found in hot peppers is nearly absent in sweet varieties like Phantom.
- 🌱 A single healthy Phantom pepper plant can produce 20-30 peppers over a season if harvested regularly to encourage continued flowering.
