Care Guide
Watering
Water deeply once every 1–2 weeks during extended dry spells
Fertilization
Apply slow-release granular fertilizer once at the start of growth. Use a balanced, low-nitrogen fertilizer to prevent weak, leggy growth
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle lightly on soil surface and water in to release nutrients gradually; avoid overapplication to prevent pH imbalancePruning
- Prune in late winter to early spring to shape; avoid heavy shearing of mature scale-like foliage
- Remove dead, diseased, or crossing branches to improve airflow and reduce pest risk
- Trim back new growth to maintain desired form for bonsai or hedge specimens
