Apply slow-release balanced fertilizer once in early spring. Avoid over-fertilization to prevent excessive foliage growth at the expense of root development

Eggshell powder top dressing:Crush clean, dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base and work lightly into topsoil to avoid pest attraction
Pruning
  • Remove dead, damaged, or diseased branches in late winter to maintain structural integrity
  • Thin overcrowded lower boughs to improve air circulation and light penetration
