Care Guide
Watering
Water occasionally during prolonged dry spells; avoid overwatering to prevent root rot
Fertilization
Diluted balanced liquid feed once monthly. Avoid high-nitrogen fertilizers to prevent excessive leaf growth at the expense of blooms
Banana peel tea：Soak 2–3 chopped banana peels in 1L of water for 3 days; dilute the infusion 1:20 with water before applying as a root drench; discard solid peels to avoid odor and pest attractionPruning
- Deadhead spent blooms promptly to limit self-seeding, as it is invasive in some regions
- Cut back stems to ground level in late autumn to encourage vigorous new growth in spring
- Remove diseased or yellowing foliage immediately to prevent the spread of fungal pathogens
