Seedling
2-3 weeksTiny seedlings emerge with first true leaves appearing within 7-14 days. Plants are very delicate and require high humidity.

Vegetative Growth
3-4 weeksPlant develops compact, bushy form with multiple stems and lush green foliage. Leaves are glossy and oval-shaped.
Pinch growing tips when 2-3 inches tall to encourage bushiness; maintain consistent moisture; feed weekly with balanced fertilizer; ensure shade in warm climates; transplant to larger containers as needed
Budding
1-2 weeksFlower buds form along stems in leaf axils; plant becomes stockier with visible flower clusters emerging.
Continue regular watering and feeding with slightly higher phosphorus fertilizer to promote blooming; maintain shade; watch for spider mites in dry conditions
Flowering
8-12 weeks or until frostAbundant coral-pink double or semi-double flowers bloom profusely throughout the plant. Flowers are about 1-1.5 inches across.
Deadhead spent flowers to encourage continuous blooming; maintain consistent watering; fertilize every 2 weeks; provide afternoon shade in intense heat; watch for powdery mildew in humid conditions
Late Season/Decline
Until frost or end of seasonPlant may become leggy or decline as temperatures drop below 60°F or with increasing shade in fall. Flowering slows or stops.
In frost-prone areas, bring containers indoors before first frost; cut back and propagate cuttings for next season; compost spent plants at season's end
