Seedling (0-3 months)
3 monthsSmall tender shoots emerge from seed with 2-4 initial leaves. Growth is slow initially.
Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Protect from strong wind. Thin seedlings if overcrowded.
Juvenile (3 months - 2 years)
1.5-2 yearsTree develops deeper root system and stronger stem. Leaves become more abundant; foliage is green and tender.
Water regularly during dry spells. Apply organic mulch around base (2-3 inches, keeping away from trunk). Support with stake if wind exposure is high. Begin light pruning to shape.
Vegetative Growth (2-5 years)
2-3 yearsTree establishes main branch structure with increasingly thick trunk. Canopy spreads wider; growth accelerates significantly.
Reduce watering frequency as tree becomes drought-tolerant. Prune lower branches for tree form. Remove competing leaders. Apply balanced fertilizer annually in spring.
Pre-Flowering (5-8 years)
2-3 yearsTree matures structurally; foliage is dense and full-sized. Small buds begin appearing on branch tips.
Maintain minimal intervention. Water during extended dry periods only. Light pruning for shape maintenance. Ensure good air circulation through canopy.
Flowering & Fruiting (8+ years)
Ongoing annuallyTree produces clusters of small white or creamy flowers, followed by small winged fruits (samaras). Peak medicinal potency occurs.
Harvest bark and leaves as needed for medicinal use. No fertilizer needed. Occasional deep watering during severe drought. Allow fallen fruit/leaves to mulch naturally.

Harvest Tips
Bark is traditionally harvested from mature trees (8+ years old) by careful, sustainable methods—scrape outer bark without girdling the trunk, allowing regeneration. Leaves can be picked year-round. Flowers and fruits are collected during blooming season (spring-early summer). For medicinal use, dried bark is most potent; dry harvested materials in shade for 2-3 weeks before storage.
