Crepe myrtle leaves will start to fall and your tree will start to look pretty shabby. So what is causing this problem?

Cercospora Leaf Spot

Cercospora Leaf Spot is a fungus that causes all the problems mentioned earlier. While it won't severely damage your tree at first, it will return each year can start hurting your tree.  The fungal spores spread from splashing water during warm wet weather. Trees in humid areas with little air flow are more severely affected.

Treating Cercospora Leaf Spot

Buy a fungicide labeled for Cercospora Leaf Spot. Treat your tree as specified on the label starting in early summer when you first notice new spots. Most products have a short control period. If so, you will need to retreat your tree every one to two weeks, depending on the product label. Thinning the branches on the crepe myrtle will lead to better airflow and reduce the chance of Cercospora Leaf Spot recurring.
