What Is Crepe Myrtle Tip Blight?

Crepe Myrtle Tip Blight is a fungal disease that affects crepe myrtle trees by attacking their new growth tips.

The main cause of Crepe Myrtle Tip Blight is warm and humid weather conditions. The fungus thrives in temperatures between 60 and 80 degrees Fahrenheit, and when the humidity levels are high. Poor air circulation around the tree can also contribute to the spread of the fungus. Additionally, over-fertilizing the tree can make it more susceptible to diseases and pests, including Crepe Myrtle Tip Blight.

Symptoms of Crepe Myrtle Tip Blight
