Japanese maples are stunning ornamental trees that are often the centerpiece of a garden. However, these elegant trees can suffer from a variety of ailments that may affect their health and appearance. Below are some common issues that you might encounter and how to address them.
## Leaf Scorch
Symptoms: Browning and drying of leaf margins, followed by curling or shriveling.

Solution: Make sure the tree is well-watered and consider adding a shade cloth to protect it from harsh sunlight.
## Verticillium Wilt

## Aphids and Scale
