Can anyone help me with a problem I seem to have with my Plum Tree?
Firstly I'll describe the tree. I don't know it's age but it's around 2ft high. It's a Prunus Avium.
The problem is that there are small a few red 'blobs' just below almost every leaf. It didn't worry me at first, but then I noticed ants on most of these blobs, and it knew it wasn't coincidence. Are the ants eating the blobs and the blobs are natural parts of the tree, or have the ants even created the blobs (e.g. eggs?!) . I don't know what to do!
If anyone can diagnose the prblem (if there is one) or/and give me any advice, I would be very grateful. I really don't want the infection to get to my beloved Goji Berry Tree!
