Fertilization
Apply a diluted balanced organic feed once in early spring. Over-fertilization can reduce bloom production and increase susceptibility to pests
Eggshell powder top-dress：Crush dried, rinsed eggshells into fine powder; sprinkle 1 teaspoon per plant in early spring, avoiding direct contact with foliage to prevent burningPruning
- Deadhead spent blooms regularly to extend the flowering period through early autumn
- Cut back all stems to 5–10 cm above basal foliage in late autumn to encourage fresh spring growth
