There is a dense thicket at the end of my patch. This year one tree has been overloaded with these yellow plum-like fruit. They are sweet, oval shaped and in all respects they are a small yellow plum. I have looked up on Google images and I think they are either a Bullace, or more probably a Mirabelle. Does anyone have an idea what they are? Meanwhile elsewhere on the patch, I have been pruning and clearing up my soft fruit bushes. It is much easier to prune redcurrants and harvest the berries whilst sitting comfortably at a table!
