Care Guide
Watering

Fertilization
Apply diluted balanced liquid fertilizer every 2 weeks. Discontinue fertilization in late summer to prepare plants for dormancy
Banana peel compost tea：Compost banana peels for 2 weeks, steep in water for 24 hours, dilute 1:20 with water, and apply as a root drench to support flower and calyx developmentPruning
- Cut back dead foliage to ground level in late winter to encourage vigorous new spring growth
- Thin overcrowded stems in early spring to improve airflow and reduce disease risk
- Deadhead spent summer blooms to promote additional flowering (optional)
- Remove faded lanterns after winter if desired, or leave them for seasonal decorative interest
