Care Guide
Watering
Keep soil consistently moist during active growth and blooming; avoid wetting foliage to reduce fungal risk
Fertilization
Apply balanced, slow-release fertilizer when new growth emerges. Avoid high-nitrogen fertilizers, which can promote foliage over flower production
Crushed eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of plants in early spring and work lightly into topsoilPruning
- Cut back dead foliage to ground level in late autumn after the first hard frost
- Stake stems in early spring before blooms emerge to support heavy double flowers
- Remove spent blooms promptly after flowering to redirect energy to root and foliage growth
- Thin overcrowded clumps every 3–4 years in autumn to improve airflow and blooming performance
