Crap... after working to save the split side of the tree, the other side started oozing sap heavily this morning, down low. I am attaching some pics for you to take a look at, but it appears to be the birch borer. I had thought the river birches were resistant, but I guess that doesn't equal immune.
Any way to treat this?
