Growth Stages

1

Establishment

6-12 months

Young tree develops root system and establishes branches. Foliage is bright green and sparse initially.

Keep soil consistently moist but not waterlogged. Provide shelter from strong winds. Support with stake if needed. Fertilize monthly with balanced fertilizer.

2

Vegetative Growth

1-2 years

Tree rapidly grows in height and branch structure. Develops compound pinnate leaves along extending branches.

Prune to shape and encourage branching. Continue regular watering. Apply mulch to retain moisture. Fertilize every 4-6 weeks during growing season.

3

Maturation

1-2 years

Tree reaches near-flowering size with fuller canopy and established branch structure.

Reduce nitrogen fertilizer to encourage flowering. Reduce watering slightly. Prune lightly to maintain shape. Begin hardening off for potential cool season.

4

Flowering & Dormancy

3-6 months flowering + dormancy

Flowers emerge on bare branches in late winter/early spring in brilliant coral-red clusters. Tree then produces leaves and may defoliate in dry season.

Minimal pruning after flowering. Allow natural leaf drop if it occurs. Reduce watering during dormant period. Do not fertilize during dormancy.

5

Fruiting

2-3 months

Produces distinctive black, bean-like seed pods that mature after flowering. Pods contain reddish-brown seeds.

Allow pods to mature and dry on tree. Collect seeds if desired for propagation. Seeds are toxic—do not consume. Allow self-seeding or collect pods before dispersal.
