Seedling
3-4 weeksTiny plants with 2-4 true leaves emerge 7-14 days after sowing
Maintain warm soil (75-85°F), high humidity, and bright indirect light. Keep soil moist. Thin seedlings if overcrowded.
Vegetative
6-10 weeksPlant develops sturdy stem, multiple branches, and dark green oval leaves; no flowers yet
Transplant into larger pots when 2-3 inches tall. Provide full sun. Fertilize every 2-3 weeks with balanced fertilizer. Prune side shoots to encourage bushiness.
Flowering
4-6 weeks, ongoingClusters of small white or pale yellow flowers appear at leaf axils
Ensure consistent watering and abundant sunlight. Switch to lower-nitrogen fertilizer (higher phosphorus/potassium). Maintain warm temperatures (70-85°F). Avoid over-fertilizing, which reduces flowering.
Fruiting
8-12 weeksSmall green peppers develop and elongate to 1-2 inches; begin color change from green to red over time
Continue consistent watering and full sun exposure. Support branches with heavy fruit using stakes or cages. Maintain warm temperatures. Continue moderate fertilizing with balanced formulation.
Harvest
Ongoing, 3-6 months of heavy productionPeppers mature to bright red color, fully developed and pungent
Harvest green peppers anytime for milder heat, or wait for full red color for maximum flavor and spice. Pick regularly to encourage continued production. Plants can produce for 2-3 years in warm climates.

Harvest Tips
Harvest green peppers anytime for a milder, grassy flavor, or allow them to fully mature to bright red for maximum heat and fruity sweetness. Use sharp scissors or pruning shears to cut peppers from the plant to avoid damaging branches. Pick regularly (every 2-3 days during peak season) to encourage continuous production. Mature peppers can be dried for use in powders and sauces. In cooler climates grown as annuals, harvest all remaining peppers before the first frost.
Fun Facts
- 🌱 Hawaiian peppers (Capsicum frutescens) are one of the few plants that will naturally self-pollinate, making them easier to grow and breed compared to other pepper varieties.
- 🌱 These peppers are typically 30,000-100,000 Scoville Heat Units, making them significantly hotter than jalapeños (2,500-8,000 SHU) but milder than habaneros (100,000-350,000 SHU).
- 🌱 Hawaiian chili peppers have been cultivated in Hawaii for centuries and were likely introduced by Polynesian voyagers; they've become so integral to Hawaiian culture that they're featured in traditional dishes and island commerce.
