Care Guide
Watering

Fertilization
Apply 5–10 cm of compost around the drip line once annually. Avoid high-nitrogen fertilizers that may reduce nut production
Composted banana peel tea：Soak fully composted banana peels in water for 3 days; dilute 1:20 with water for root drench to avoid burning rootsPruning
- Remove dead, diseased, or crossing branches in late winter to improve airflow
- Thin crowded upper branches to increase light penetration for nut production
- Avoid heavy pruning, as shagbark hickories have slow regrowth rates
