My plumb tree seems to have a disease that i can't seem to diagnose. On all the newly grown stems there are tiny,raised, circular lumps which dip in the middle. Could it be something to do with the aphids that i have just got rid of which were curling the leaves? They seem to appear in twos either side the base of the leaves. I have been on every website i know to try and find out what this is but no luck as yet.
