While it is famous for surviving in
Low Light, it will grow more robustly in
Bright Indirect Light. Avoid direct sunlight, which will scorch the leaves.
Watering

Seasonal Care
Spring/Summer: This is the active growth phase. Keep the soil slightly more moist and fertilize monthly. *
Fall/Winter: Reduce watering significantly as growth slows down. Do not fertilize during these months.
Maintenance
Cleaning: Dust the large leaves regularly with a damp cloth to help the plant breathe. *
Repotting: Because it is slow-growing, it only needs repotting every 3-4 years.
