Growth Characteristics
- Environment: It thrives in partial shade, and it is best to avoid direct sunlight. Strong sunlight can burn the leaves.
- Temperature: It prefers temperatures between 18 and 24 degrees Celsius. Since it is sensitive to cold, special attention must be paid to indoor temperature management during the winter.
- Humidity: It likes high humidity. In dry environments, leaf tips may turn brown, so it is recommended to mist the surrounding air periodically.

Propagation Methods
- Division: The most common method of propagation is division. You can divide the root ball and plant it when repotting in spring or early summer. Plant the divided roots in a new pot and provide sufficient moisture. Cultivation Method

Important Pests and Control Methods
- Spider Mites: Spider mites can easily occur in dry environments. They can be prevented by increasing surrounding humidity along with periodic misting. If spider mites appear, apply soapy water or use appropriate pesticides.
- Scale Insects: If scale insects appear, remove them physically using a cotton swab soaked in alcohol, or eliminate them using pesticides that control the specific disease. - Leaf blight: Leaf blight can occur due to excessive moisture or poor ventilation. It can be prevented by adjusting watering and ensuring good air circulation.
