Juvenile Growth
2-4 yearsYoung tree develops compound pinnate leaves and establishes main stem; grows 1-3 feet annually in favorable conditions
Stake for support if needed. Begin light pruning to shape form. Continue consistent watering. Mulch around base to retain moisture.
Vegetative Development
3-7 yearsTree develops strong branch structure and increased leaf mass; reaches 15-40 feet with spreading canopy
Thin crowded branches to improve form and air circulation. Apply balanced fertilizer annually. Maintain consistent watering schedule.
Flowering & Reproduction
Seasonal, typically springTree produces small clusters of yellowish flowers and develops woody capsules containing winged seeds
Minimal intervention needed. Allow natural seed development if you wish to collect seeds. Mature trees flower reliably.
Mature Growth & Timber Development
Ongoing after 15+ yearsTree reaches full size with dense heartwood accumulation and rich color development in wood
Maintain health through light pruning and pest monitoring. Allow natural senescence. Timber quality improves with age.

Harvest Tips
Allow tree to mature 15-20+ years before harvesting timber. Collect seed capsules in dry season when they turn brown and split naturally; seeds have papery wings for wind dispersal. For ornamental/shade purposes, no harvest is needed—simply maintain tree health through regular monitoring and light pruning.
Fun Facts
