Seedling
2-3 weeksTiny plants with first true leaves emerging, very delicate and small
Keep soil evenly moist; provide warm temperatures (70-75°F); use grow lights if indoors; avoid overwatering which causes damping off
Establishment
3-4 weeksYoung plants developing multiple leaf pairs with initial color variation becoming visible
Gradually acclimate to outdoor conditions if grown indoors; begin light fertilization; pinch tips to encourage bushiness; maintain consistent moisture
Vegetative Growth
6-10 weeksVigorous branching with increasingly colorful foliage showing red, purple, orange, and green patterns
Apply balanced fertilizer every 2-3 weeks; pinch growing tips regularly to promote dense, compact form; maintain consistent watering; ensure full sun exposure
Peak Ornamental Color
Continuous through seasonPlant reaches full maturity with maximum color intensity and foliage density
Continue regular fertilization; deadhead any insignificant flowers; monitor for pests; provide consistent sunlight and moisture for color vibrancy
Winter/Senescence
Variable based on climateColor may fade in cool temperatures; growth slows significantly in zones below 10
In cool zones, bring containers indoors before frost; reduce watering and fertilizing; in warm zones, continue normal care; can rejuvenate with spring pruning
