I have a Mimosa tree with a split in the main trunk at a Y. Is the proper fix a brace, or bolt the Y in place? Do I need to cut the bark at the split to help the bark to mend back together? I would like to save the tree from splitting the rest of the way and losing half or all of the tree. Plus, is there a disease going around for Mimosa that causes the sap to boil out and the tree to curl up and die? This happened to 2 of my mother's trees.
