Most likely
How to tell: Leaves turn yellow and wilt on one side of the tree before spreading. You might see dark streaks in the wood if you cut a small branch.
What to do: Unfortunately, there is no cure for this fungal disease. Remove and destroy the affected tree to prevent the fungus from spreading to others in your garden.
Overwatering
Possible
How to tell: The soil feels constantly soggy and the leaves turn yellow starting from the bottom. The roots may smell sour or look mushy.
What to do: Stop watering immediately and let the top 3 inches of soil dry out. Ensure the planting site has excellent drainage and avoid watering if the ground is still damp.

When to worry

Stopping it coming back

Plant resistant varieties if available and avoid wounding the roots or trunk during landscaping. Keep the tree healthy with proper spacing to ensure good airflow.
