Germination & Seedling
2-3 weeksTiny seedlings with cotyledons emerge; very slow initial growth over 2-3 weeks
Keep soil moist and warm (70-75°F); provide consistent bright light; avoid waterlogging which causes damping-off disease
Vegetative Growth
4-6 weeksPlant develops true leaves and branching structure; roots establish deeply; foliage is soft green with serrated edges
Maintain warm temperatures (65-75°F); water consistently; apply balanced fertilizer every 2-3 weeks; pinch back early growth to encourage branching
Bud Formation
2-3 weeksTerminal and lateral buds appear at branch tips; buds are small, tight, and pale green
Switch to phosphorus-rich fertilizer to promote flowering; maintain consistent moisture; ensure adequate light
Flowering
6-12 weeksLarge, double white flowers open progressively along stems; blooms are ruffled and full, resembling roses; flowers last 1-2 weeks each
Continue regular watering and fertilizing; deadhead spent flowers to encourage more blooms; provide support with stakes if needed; maintain temperatures 60-70°F for longevity
Seed Development & Dormancy
4-8 weeksFlowers fade and seed pods form if not deadheaded; plant may enter dormancy in winter in cooler climates
Allow some flowers to set seed for future propagation if desired; reduce watering significantly in dormancy; minimal fertilizing needed
