Care Guide

Watering

Keep soil consistently moist during active growth; apply 5–7 cm of organic mulch to retain moisture

Fertilization

Apply balanced organic fertilizer once in early spring before new growth. Do not fertilize in autumn or winter to prevent frost damage to new, tender growth

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of the tree in early spring; work lightly into the top 2 cm of soil to avoid disturbing shallow roots
Pruning
  • Remove dead, damaged, or crossing branches in late winter before new growth emerges to maintain tree health.
  • Thin crowded inner branches to improve air circulation and light penetration for better flowering.
  • Prune lightly to maintain desired shape; avoid heavy pruning as it can reduce flowering in subsequent growing seasons.
