Germination & Seedling
3-4 weeksSeeds sprout within 2-3 weeks under warm, moist conditions. Seedlings develop compound leaves and a single central stem.
Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Thin to strongest seedlings if crowded. Maintain temperatures above 70°F.
Vegetative Growth
1-2 yearsYoung tree develops compound pinnate leaves, establishing a strong root system and trunk structure. Growth is relatively rapid in tropical conditions.
Water regularly during dry spells. Apply balanced fertilizer monthly during growing season. Mulch around base to retain moisture and regulate soil temperature. Prune to shape if desired.
Pre-flowering
6-12 months before first bloomTree reaches maturity with full canopy development. Buds begin forming on branch tips as the tree prepares to flower.
Continue regular watering and monthly fertilizing. Reduce nitrogen to encourage flowering. Remove lower branches if desired for aesthetics. Prune dead or crossing branches.
Flowering & Fruiting
2-3 months flowering; 4-5 months for pod maturationDelicate pink and white flowers appear in clusters, followed by flat, elongated winged pods (samaras) containing seeds. Blooms typically occur in spring.
Maintain consistent moisture during flowering. Avoid heavy pruning during bloom. Allow some flowers to set seed if propagation desired. Monitor for pests attracted to flowering trees.
Dormancy & Rest
2-4 months depending on climateTree may drop foliage in cooler months or during dry season. Growth slows significantly as the tree rests and conserves energy.
Reduce watering frequency. Hold off on fertilizing. Clean up fallen leaves and pods. Prune dead growth. Prepare for next growth cycle.

Harvest Tips
Harvest seed pods in late summer or early fall when they turn brown and papery. Allow pods to dry completely before extracting seeds. For medicinal bark harvesting, prune branches in late winter and dry the bark in shade. Sustainable harvesting means taking no more than 10-15% of the canopy annually.
