Care Guide
Watering
Keep soil evenly moist during active growth periods
Fertilization
Apply a balanced diluted feed once at the start of growth. Avoid over-fertilizing, as this can reduce flower production and promote excessive foliage growth
Eggshell powder topdress：Crush clean, dried eggshells into fine powder; sprinkle lightly on soil surface and gently work into the top layer to boost soil calcium levels without causing nutrient burnPruning
- Trim back spent flower heads to encourage prolonged blooming and prevent self-seeding if desired
- Mow or cut back to 5 cm in late autumn to tidy growth and promote dense spring regrowth
- Thin overcrowded clumps every 2–3 years to improve airflow and reduce disease risk
