Seedling
2-3 weeksTiny plants with first true leaves emerging, very delicate and pale green
Keep soil warm (70-80°F) and moist under grow lights. Provide 12-16 hours of light daily. Avoid overwatering to prevent damping-off disease.
Vegetative
3-4 weeksPlants developing multiple sets of true leaves, becoming bushier with stronger stems and darker green foliage
Harden off gradually before transplanting. Pinch back growing tips at 4-6 inches tall to encourage branching. Maintain consistent moisture and warmth.
Pre-flowering
2-3 weeksCompact, bushy plants 8-12 inches tall with flower buds beginning to form at branch tips
Ensure full sun exposure and maintain soil temperatures 65-75°F. Continue regular fertilizing every 2-3 weeks with balanced or slightly higher phosphorus fertilizer.
Flowering & Fruiting
4-6 weeksSmall white flowers appear, followed by tiny green peppers that begin the color transition from yellow to orange to red
Maintain consistent watering and don't allow plants to dry out. The multi-colored fruit display is most striking when peppers are at different stages simultaneously. Pollinate flowers by gently shaking plants.
Mature & Harvest
Until frost or plant declinePeppers fully colored and glossy, plants heavy with fruit in various stages of ripeness creating the 'forest fire' appearance
Continue regular watering and feeding. Harvest peppers at any stage for ornamental display or wait for full ripeness. Remove fruit regularly to encourage continuous production.
