Question: Why Do My Crepe Myrtle Shrubs Have Brown Leaves?
The reason for a crepe myrtle shrubs having brown leaves depends on the time of year....
Answer:
If you're seeing brown leaves (or partially brown leaves) on crepe myrtle shrubs at the end of a dry summer, your crepe myrtle's brown leaves could be due to drought. If, by contrast, you're seeing brown leaves on crepe myrtle in spring, it could be the result of a cold snap.
Neither case of brown leaves need be fatal to your crepe myrtle. Browning due to a moderate cold snap ruins the appearance of the crepe myrtle but probably won't kill the shrub. And while a crepe myrtle shrub is more likely to die from drought, it's usually easy enough to remedy the situation with irrigation.
