Care Guide
Watering
Water deeply during prolonged dry periods; avoid overwatering to prevent root rot
Fertilization
Apply slow-release balanced fertilizer once in early spring. Avoid high-nitrogen fertilizers which can promote weak, disease-prone growth
Composted eggshell powder：Sprinkle a thin layer around the tree base in early spring; avoid direct contact with the trunk to prevent bark burnPruning
- Remove dead, damaged, or crossing branches in late winter to improve airflow and reduce disease risk
- Thin crowded inner branches to maintain an open, rounded crown structure
- Avoid heavy pruning, as oak trees heal slowly and are susceptible to fungal infections
