Care Guide

Watering

Keep soil consistently moist during active growth periods

Fertilization

Apply balanced slow-release fertilizer once after new growth emerges. Avoid over-fertilizing to prevent excessive vegetative growth at the expense of flowering

Eggshell powder topdress:Grind dried eggshells to a fine powder; sprinkle 1–2 tbsp around the drip line once every 6 months; avoid direct contact with tree stems
Pruning
  • Remove dead, damaged, or crossing branches in late winter before new growth begins
  • Thin crowded inner branches to improve air circulation and light penetration
  • Shape lightly immediately after flowering to maintain desired form; avoid heavy pruning that reduces next year's bloom potential
