Care Guide
Watering
Keep soil consistently moist during active growth to support flowering
Fertilization
Apply diluted organic liquid fertilizer once monthly to support bloom production. Use a balanced, low-nitrogen fertilizer to promote flowering rather than excessive foliage growth
Composted eggshell powder：Crush dried eggshells into fine powder, mix into the top 2 cm of soil in early spring; avoid overapplication to prevent soil alkalinityPruning
- Deadhead spent flower clusters regularly to encourage prolonged blooming through spring
- Cut back all foliage to ground level in late autumn to tidy growth and prepare for winter dormancy
- Remove yellowing or damaged leaves throughout the growing season to maintain plant health and airflow
