Establishment
First 1-2 years after plantingYoung 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.
Vegetative Growth
Years 2-4Tree 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.
Flowering
May-June, 2-4 weeksTree 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.
Fruiting
July-September development; persist through winterSmall 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.
Dormancy
October-MarchTree 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.
