New client has about 20 to 30 trees lining his driveway. They all have, to some extent, this white powdery mold on them. He sent me some pictures as we havent started to work on his property yet. I'll head out there tomorrow to take a look, just curious if anyone had any info on this or ideas on how to go about treating it. Thanks- Seen it before and had some info on it but cant find it now.
