Care Guide

Watering

Water regularly during prolonged dry spells; allow soil to dry slightly between waterings

Fertilization

Apply a balanced slow-release fertilizer once in early spring. Avoid over-fertilizing to prevent excessive leaf growth at the expense of blooms and berries

Composted eggshell powder:Sprinkle a thin layer around the base in early spring; avoid direct contact with stems to prevent potential burn
Pruning
  • Prune in late winter to shape the shrub and remove dead, damaged, or crossing branches
  • Thin dense inner growth to improve airflow and reduce fungal disease risk
  • Trim back overgrown stems to maintain desired size and compact habit
