Care Guide

Watering

Keep soil consistently moist during active growth; avoid waterlogging

Fertilization

Apply balanced slow-release fertilizer once in early spring. Use low-nitrogen fertilizer to promote flowering rather than excessive foliage growth

Eggshell powder topdress:Crush dried eggshells into fine powder; sprinkle 1 tbsp per plant around the base and work lightly into the top 2 cm of soil
Pruning
  • Remove dead, damaged, or crossing branches in late winter to early spring
  • Thin overcrowded stems to improve airflow and light penetration
  • Shape lightly after flowering to maintain a rounded form; avoid heavy pruning that reduces next year's bloom production
