Care Guide
Watering
Deep water every 7–10 days during dry spells; avoid overwatering
Fertilization
Apply balanced slow-release fertilizer once at bud break. Avoid high-nitrogen feeds to prevent weak, leggy growth.
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of the tree and water in to release nutrients gradually.Pruning
- Remove dead or damaged branches in late winter to maintain a clean, upright form.
- Thin overcrowded interior branches to improve airflow and reduce disease risk.
- Trim suckers growing from the base to prevent unwanted spreading.
- Avoid heavy pruning, as it can disrupt the tree's tight columnar silhouette.
