Critique these pruning cuts on American Elm
I'm consistently seeing this kind of callusing pattern on the pruning cuts I'm making on my American elms. You can see the horseshoe shape rather than the ideal circle of callus. These elms are prone to tight branching angles with some included bark, making the pruning cuts a bit tricky. Is the best I can expect, or am I doing something wrong? The cuts I make on other trees grow over just fine.
