Elm Tree leaves turning brown

Asked June 6, 2016, 5:47 PM EDT

I have a large elm in my backyard. Many leaves are spotted and look like they are drying out. On closer inspection it seems as if they are being eaten by a very small mite. This has gone on for a few years. Is there some way to treat this? Your suggestions would be greatly appreciated. Thanks, Frank Crotti Corvallis

Elms are pretty susceptible to leaf miners and the elm leaf beetle.

you might try contacting the Master Gardeners at the Benton County Extension office for further assistance.
