Care Guide
Water frequently to keep the soil evenly moist, ensuring high humidity.
Apply a diluted liquid fertilizer every two weeks as new growth appears.. Use a diluted balanced fertilizer during the active growing season.
Banana Peel Tea：Steep chopped banana peels in water for 24-48 hours, strain, and use the liquid to water the plant. Helps support robust tuber development. Avoid leaving raw peels on the soil to prevent pests.- Remove dead or yellowing leaves at the base to maintain a tidy appearance;
- Cut back all foliage once it naturally dies down in autumn to prepare for dormancy;
- Snip off flower spathes if they appear, to direct the plant's energy back into foliage and tuber growth.
