Watering

Fertilization

Diluted balanced liquid feed every 2 weeks. Cease fertilization in autumn and winter when growth slows

Composted banana peel tea：Steep fully composted banana peels in water for 24 hours, dilute 1:20, and apply as a root drench to support leaf growth

Pruning

Remove yellow or damaged leaves at the base of the petiole to maintain plant appearance and reduce pest habitat
Trim overcrowded petioles to improve airflow and prevent fungal infections
Repot in early spring and trim circling roots to encourage healthy root development
