I have a small split in the branch where it splits off it has broken and torn about a 1/4" its not hanging or anything but it is starting to tear the branch more and more. I have tied it together but is this going to kill those branches? Can anything else be done? Is there anything I can put on the tear like a sealent or anything to help it repair its self?Thanks . I will post a pic of the tear later to show you what I have done.
