Lilac tree #276538

Asked September 08, 2015, 11:50 AM EDT

Good morning---my lilac tree looks like it has some type of disease--our gardening service can not identify the problem. Is there any specific disease that is affecting lilac trees this year? If I sent a picture of a leaf would that help identi=fy the issue? thank you John Ferrara

Expert Response

Hi John:
Can you send a picture or two? If the leaves are covered in white, it is powdery mildew.

Hi John:
I am not sure what is causing this. Are there any other plants nearby with similar symptoms? Would you be able to bring samples into the Montgomery County Extension office? If the Master Gardeners cannot figure it out, they could send a sample to the Disease Clinic.
