Q: I need help. A big pecan limb split away from a similar-sized limb way up in the tree. Do you think I should cut off the whole limb to which both are attached?
A: Someone brave is going to have to climb up in the tree and cut away the original limb that snapped. I HIGHLY suggest you hire a professional arborist to do the work. In my opinion, the twin limb that remains can be left on the tree. Even though the wound is substantial, an arborist can trim the big splinters around the crack and let the tree heal the wound in its own way.
If, on the other hand, you arborist says everything needs to be removed, follow their advice.
