Fertilization
Apply diluted balanced fertilizer once monthly. Use a low-nitrogen fertilizer to prioritize bloom production over foliage growth
Eggshell powder topdressing：Crush dried, rinsed eggshells into fine powder; sprinkle lightly on soil surface and water in to release calcium gradually without odor or pest issuesPruning
- Deadhead spent blooms regularly to extend the flowering period through early summer
- Trim faded stems to ground level in late autumn to tidy growth and prepare for winter dormancy
