Seedling
2-3 weeksTiny seedlings emerge with cotyledons and first true leaves appearing within 10-15 days. Plants are delicate and translucent.
Maintain high humidity (60-70%), keep soil moist, provide bright indirect light, and avoid touching fragile seedlings. Use bottom heat (70-75°F) to encourage germination.
Vegetative Growth
4-6 weeksYoung plants develop multiple stems and leaves with characteristic silvery or speckled foliage. Plant becomes bushier and more compact.
Pinch stem tips to encourage branching. Maintain consistent moisture and bright light. Feed lightly with diluted balanced fertilizer every 2 weeks.
Budding
2-3 weeksSmall flower buds form in clusters at stem terminals. Foliage becomes more prominent and silvery speckles are visible.
Continue consistent watering and light. Increase fertilizer slightly (switch to bloom-promoting formula with higher phosphorus). Remove any damaged or weak growth.
Flowering
8-12 weeks or longerDelicate pink or white flowers bloom in small clusters. Plant produces continuous blooms with proper care. Flowers are typically small but numerous.
Maintain bright indirect light and warm temperatures (65-75°F). Deadhead spent flowers to encourage more blooms. Keep humidity moderate (50-60%) and avoid wetting flowers.
Decline & Rest
3-4 monthsFlowering slows as temperatures cool in fall/winter. Plant may lose some leaves and growth rate decreases naturally.
Reduce watering frequency and fertilizing. Provide cooler temperatures (55-65°F) for dormancy period. Resume normal care in spring when new growth emerges.
