Don't like to admit it, but I have a neighbor whoose tree roots are climbing into my sewer line. Had it snaked and nothing but roots. How can I silently end this trees life? Its right on the line but it is clearly his and wouldn't consider asking him to remove it, but if in the Spring, it has no leaves... maybe he will remove it. Its a crappy Mulberry tree and drops those berries all over my lawn. Is there a injection I can give it? Or, a gallon of Tri-ox during the night do the trick?? I'm sorry if this seems harsh, I love trees, but when its costing me $ and agravation, thats where it stops.
