Did someone take a hole punch to my Rhodi? Or is it weevils?
I recently received a Northern Hi-Lights Rhododendron from a well respected mail order site and after returning from a long weekend getaway I've found neat round holes all over the leaves. It really does look like a hole puncher was taken to my plant (see pics below).
I have another rhodi that has been completely healthy and pest free for the 2 years I've owned it. I've moved the infected plant away from the clean plant.
Can someone please tell me what this pest is and how best to treat it. My current theory is that it's Black Vine Weevil and I'm thinking of purchasing some nematodes. But I'd really like to be sure about it before I try any treatments.
Thanks in advance for your help!
