## Why are my Calathea leaves curling

Calatheas are known for their beautiful foliage, but they are also sensitive plants that quickly show signs of stress. Curling leaves are one of the most common issues and usually indicate a problem with moisture, humidity, or environment.

The good news is that this is often easy to fix once you identify the cause.
