My walnut tree has indentations on the leaves, I cannot see any bugs on there that may have caused this, is this something to be concerned about and treated?
Looks like some kind of gall, I don't know which ones live on walnut
It is a leaf gall mite. I found this site when I saw these bumps on my tree.
I have a lot of galls but that's a new one for me. My walnut has something to look forward to
Thanks all, have other people with this problem removed the leaves as suggested with any success or is it just a case of leave it alone?
Outdoor girls link suggests it's not too much of a problem. Most galls aren't
I have the same on my tree and tend to just leave it. Hasnt seemed to do any harm.
Thank you all for your replies, I shall just leave it be and hope for the best
