Growth Stages

1

Establishment

First 1-2 years after planting

Young sapling with developing root system and initial branch structure

Water regularly to keep soil consistently moist but not waterlogged. Apply 2-3 inches of mulch around base. Stake if in windy locations. Do not fertilize excessively.

2

Vegetative Growth

Years 2-4

Tree develops branching structure and establishes canopy form with distinctive compound, fern-like leaves

Remove competing central leaders if needed. Prune lower branches to create desired form. Maintain consistent watering. Monitor for pest issues.

3

Flowering

May-June, 2-4 weeks

Tree produces clusters of small white to cream-colored flowers in late spring

Minimal intervention needed. Flowers are self-fertile but benefit from insect visitation. Do not prune heavily during flowering period.

4

Fruiting

July-September development; persist through winter

Small round berries develop from spent flowers, gradually transitioning from green to bright yellow-orange as they mature

Berries are non-toxic and attract birds. Do not harvest fruit unless specifically needed; let birds feed naturally. Avoid over-pruning to maximize fruit production.

5

Dormancy

October-March

Tree loses compound leaves in autumn, displaying warm fall colors before entering winter rest with persistent berry display

Minimal maintenance required. Prune dead or damaged branches during dormancy. Do not rake fallen leaves; allow natural mulch layer. Avoid late-season nitrogen fertilization.

Common Pests

  • Monitor foliage for skeletonized leaves; spray with neem oil or insecticidal soap if severe; encourage natural predators

  • Prune affected branches; maintain tree vigor through proper watering and care; rarely requires chemical intervention

  • Prune infected branches 12 inches below visible damage; sterilize pruning tools between cuts; avoid nitrogen-rich fertilizers that encourage succulent growth

  • Spray with strong water stream; apply insecticidal soap or neem oil; natural predators usually control populations

  • and

    Improve air circulation through selective pruning; remove infected branches; ensure proper drainage; avoid overhead watering
