Seedling
2-3 weeksTiny plants with first true leaves appearing; delicate and pale green
Keep soil moist; maintain warm temperatures (75-85°F); provide bottom heat if indoor; avoid overwatering which causes damping off
Vegetative
4-6 weeksPlant develops bushy growth with multiple stems and dark green leaves; no flowers yet
Provide full sun; fertilize every 2 weeks with balanced fertilizer; pinch off top shoots to encourage bushier growth; transplant outdoors after last frost
Flowering
3-4 weeksSmall white flowers appear at leaf nodes; plant is compact and vigorous
Maintain consistent watering; switch to slightly higher phosphorus fertilizer to support blooming; ensure adequate sunlight; avoid over-fertilizing with nitrogen which inhibits flowers
Fruiting
4-6 weeksGreen peppers develop rapidly from flower sites; peppers grow upright pointing toward sky
Continue regular watering; provide balanced to potassium-rich fertilizer for fruit development; support heavy branches with stakes if needed; thin fruit if oversized peppers desired
Maturation & Harvest
