Care Guide
Watering
Water newly planted shrubs regularly to establish roots; established plants need minimal supplemental water
Fertilization
Apply a balanced slow-release fertilizer once at the start of growth. Avoid high-nitrogen fertilizers, which can promote excessive leaf growth at the expense of flowers
Eggshell powder topdress：Crush dried eggshells into fine powder and sprinkle lightly around the base of the shrub; avoid direct contact with stems to prevent irritationPruning
- Prune immediately after flowering to maintain a compact shape and encourage new growth for the following year
- Remove dead, diseased, or damaged branches in late winter to improve airflow
- Thin dense inner growth to reduce the risk of fungal diseases and promote even flowering
