Problems with Golden Elm
I have had a golden elm in the garden since we moved in 2005. Originally just a stick it has now grown into a largish tree. It has been fine until a couple of years ago when it suddenly 'sprouted' two green branches. This year it has developed some 'bumps'on some of the leaves. I haven't seen this before and have no idea what to do about the 'bumps' or the green branches.Can anyone help please.
