Water: Maintain consistent moisture in the soil, ensuring it remains lightly moist but not waterlogged. Allow the top layer of the substrate to dry out slightly between waterings to prevent root rot. A well-draining, airy soil mix is essential to mimic its natural growing conditions. 

Light: Provide bright, indirect light to support healthy growth. Avoid direct sunlight, which can scorch the leaves, while insufficient light may slow growth and reduce leaf size.

Humidity: This species thrives in moderate to high humidity levels, ideally between 60-80%. Maintaining stable humidity is crucial, as fluctuations can stress the plant. 

Temperature: Maintain indoor temperatures between 19-24°C for optimal growth. Avoid exposing the plant to cold drafts or sudden temperature fluctuations, as these can cause stress and hinder growth.
