Care Priorities
The Cast Iron Plant's main needs are consistent, but not excessive, watering and protection from direct sunlight.
- Light: Prefers low to medium indirect light; direct sun can scorch leaves.

Common Problems
The most common issue for Cast Iron Plants is root rot, caused by overwatering. Yellowing leaves and soft stems are key indicators. Ensure proper drainage and allow the soil to dry between waterings. While generally pest-resistant, keep an eye out for spider mites or mealybugs, especially in dry conditions.
