A gray white, dusty film on dogwood and crepe myrtle leaves across Frederick County right now is powdery mildew, and warm, humid weather is exactly the condition it thrives on.
It rarely kills an established tree outright, but it does stress the leaves and cuts into the tree's ability to photosynthesize and build energy reserves for next season.
Good airflow through the canopy is the most effective long term defense, which usually means selective thinning rather than repeated chemical treatment.
Frederick County homeowners seeing this coating on a dogwood or crepe myrtle can request an assessment to confirm the cause and the right next step.
