Looking for advice on crossed branches
I have a 5-year old plum tree, and I never noticed before that it has two branches at the base that are just about touching. I've heard, in general, that one should remove one of the branches in this situation. However, I hate to destroy the symmetry of the tree as these are fairly major branches, if I don't have to. These two branches are unlikely to produce a rubbing injury as they are so close to the trunk, but it is clear that they are just about to grow together. Here is a shot of the tree, and then a closeup, showing what I'm dealing with. I would appreciate any opinions on whether I need to prune, and, if I don't, what can happen. Thanks.
