Question: I discovered rows of holes on the trunk of one of my new pine trees, and the holes are oozing sap. I have never seen anything like this, and I don’t want the tree to die above all these holes. I thought maybe house caulk would stop the sap, and the tree might heal itself. Can I save the upper part of the tree?
