Apply a low-nitrogen, balanced diluted fertilizer once at planting. Avoid over-fertilizing to prevent excessive foliage growth at the expense of blooms
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle lightly on the soil surface to add calcium without altering soil pHPruning
- Deadhead spent blooms regularly to encourage prolonged flowering
- Remove yellowing or damaged foliage to improve airflow and reduce disease risk
- Cut back the entire plant to ground level after flowering to prepare for seed collection or disposal
