Eggshell powder topdressing：Sprinkle a thin layer of crushed, dried eggshells around the base of the tree; avoid direct contact with the trunk to prevent rotPruning
- Prune new spring candles by half to control growth and maintain a compact, contorted shape
- Remove dead, diseased, or crossing branches annually to improve airflow and structural integrity
- Thin overcrowded foliage to enhance exposure to sun and reduce pest risk
