This species needs frequent watering to maintain substrate moisture, especially when young or during the hot months. However, it's important to avoid waterlogging, as this can cause root problems.
- Summer: More abundant watering to ensure constant humidity
- Winter: Reduce frequency, but avoid allowing the substrate to dry out completely.
- Dry environment: It is advisable to spray the leaves periodically
