Care Guide
Watering
Keep soil evenly moist during active growth; avoid overwatering to prevent root rot
Fertilization
Apply a light balanced granular feed once at the start of growth. No fertilization needed in poor, lean soils
Crushed eggshell powder：Sprinkle a thin layer on the soil surface and water in to release nutrients; avoid overapplication to prevent soil alkalinityPruning
- Deadhead spent bloom clusters regularly to encourage prolonged flowering
- Cut back stems to basal foliage after the first frost to tidy the plant and prepare for winter
- Thin overcrowded clumps every 2–3 years in early spring to improve airflow and reduce disease risk
