Seedling
3-4 weeksTiny green shoots emerge with first true leaves appearing within 2-3 weeks. Seedlings are delicate with soft stems.
Keep soil warm (70-80°F) and moist. Provide bright indirect light. Maintain high humidity and protect from drafts.
Vegetative Growth
6-12 monthsPlant develops sturdy woody stems and large, soft, oval-shaped leaves. Growth is vigorous with stems thickening and branching.
Fertilize every 2 weeks with balanced or slightly high-nitrogen fertilizer. Prune to encourage branching structure. Ensure consistent moisture and warmth.
Pre-flowering
4-8 weeksLeaf growth slows and flower buds begin forming at branch terminals. Plant becomes more compact and bushy.
Shift to slightly higher phosphorus and potassium fertilizer to promote blooming. Maintain consistent watering and full sun exposure.
Flowering
3-6 months (often summer through fall)Large, spectacular trumpet flowers emerge, typically drooping downward. Flowers are fragrant, especially in evening. Multiple blooms open sequentially over months.
Continue regular feeding with bloom-promoting fertilizer. Deadhead spent flowers to encourage more blooms. Maintain moisture and warmth for continuous flowering.
Dormancy (Winter)
2-4 monthsPlant may lose leaves in cooler conditions or slow growth significantly. Flower production decreases or ceases.
Reduce watering substantially. Minimize fertilizing. Prune back dead or weak growth. Move containers indoors in zones below 9b. Keep relatively cool but frost-free.
