Growth Stages

1

Seedling

4-6 weeks

Small plants with few compound leaflets emerging from soil or containers

Keep soil consistently moist but not waterlogged. Provide bright, indirect light. Protect from cold drafts and temperature fluctuations.

2

Young Growth

1-2 years

Developing juvenile tree with increasingly compound leaves and slower growth pattern

Gradually acclimate to full sun. Maintain moderate moisture. Provide support structure or light staking if needed. Apply balanced fertilizer monthly during growing season.

3

Establishment

2-4 years

Tree becoming more robust with thickening trunk and fuller canopy; may reach 10-15 feet

Reduce watering frequency as drought tolerance increases. Prune to shape and remove crossing branches. Begin light fertilization with low-nitrogen formula.

4

Pre-Flowering

1-2 years before first blooms

Mature tree with dense foliage, typically 15-25 feet tall; flowering begins or is imminent

Encourage flowering by reducing nitrogen fertilizer and providing consistent sunlight. Prune lightly to maintain shape. Ensure good air circulation.

5

Flowering & Fruiting

4-6 months annually (flowering); year-round (mature pods)

Tree produces cascades of bright yellow flowers followed by long, dark brown seed pods; cycle repeats annually

Deadhead spent flowers if desired to prolong blooming. Reduce water during and after flowering. Monitor for pests and diseases. Collect seed pods for propagation.
