I had a large (20 ft) river birch planted in our yard last fall. This spring it has shown poor leaf development, with much fewer leaves than I expected.
The other day I discovered green flying aphids on some red osier dogwoods in another part of the yard. When I checked lower leaves on the birch I noticed some pale nodules on the underside of some leaves.
From the reading I’ve done I believe these might be leaf galls from aphid damage. I’ve attached pics of these nodules, as well as a pic of one of the green bugs, which I suspect is an aphid.
Could anyone confirm my assessment (or tell me what I’m dealing with), and let me know how to remedy this situation? Thanks in advance.
