Keep soil consistently moist during active growth and blooming periods
Fertilization
Apply balanced diluted liquid feed once monthly. Use a low-nitrogen feed to promote flower production rather than excessive foliage growth
Composted eggshell powder：Mix 1 tbsp of crushed, fully composted eggshell powder into the top 5 cm of soil in early spring to boost calcium levels and support strong stem growth; avoid direct contact with plant rootsPruning
- Deadhead spent flower stalks after blooming to redirect energy to basal foliage and root growth
- Trim yellowing or damaged basal leaves in early spring to maintain a tidy clump appearance
- Divide overcrowded clumps every 3–4 years in autumn to promote healthy growth and flowering
