Care Guide
Watering
Maintain even soil moisture; apply mulch to retain moisture and regulate soil temperature
Fertilization
Apply a balanced, slow-release organic fertilizer once in early spring. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of blooms
Banana peel compost tea：Use fully composted banana peels diluted 1:20 with water for root drenching; avoid raw peels to prevent pest infestations and odorPruning
- Remove spent flower spikes after blooming to redirect energy to rhizome growth
- Cut back dead foliage to ground level in late autumn to reduce overwintering pest habitat
- Thin crowded clumps every 3–4 years in early spring to improve airflow and reduce competition
