We have a large walnut tree in the yard that has a split down the middle of the trunk, all the way to the ground. The circumference of the tree is about 145", so it's a fairly old tree and we'd like to keep it around awhile longer if possible. Question: I've attempted to contact some local arborists in the area to look at it, but what is your gut feel for a tree this large? Is it possible to "repair" a tree like this and keep the split from getting worse, or would it just be easier to take the tree down now and avoid the expense of trying to save it?
