Cast Iron Plant Care Guide
Lighting
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
Water when the top 2 inches of soil are dry. It is drought-tolerant, so it is better to underwater than overwater. Ensure the pot has drainage holes to prevent root rot.
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.
Troubleshooting
- Brown Tips: Usually a sign of low humidity or tap water chemicals. Try using filtered water.
- Yellow Leaves: Typically indicates overwatering.
