Apply diluted low-nitrogen liquid feed once monthly. Avoid high-nitrogen fertilizers, which can promote leafy growth at the expense of flowering
Crushed eggshell top-dress：Sprinkle finely crushed eggshell powder around the base in early spring to boost soil calcium and improve drainage; avoid direct contact with foliagePruning
- Deadhead spent flower stalks after blooming to maintain a tidy clump
