Care Guide
Watering
Water deeply during dry spells to maintain even soil moisture
Fertilization
Apply a layer of compost around the base of plants. Avoid high-nitrogen fertilizers to prevent excessive leaf growth at the expense of stalk production
Banana peel compost tea：Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 for root drench; avoid raw peels to prevent pest infestationsPruning
- Remove flower stalks immediately to redirect energy to edible stalk production
- Cut back dead foliage to ground level in late autumn after dormancy sets in
- Thin overcrowded clumps every 3–4 years to improve airflow and vigor
