I am doing a job were I am replacing a lawn. I posted questions about how to do this last week and got great advice. Well the neighbor came over yesterday and wants his lawn replaced as well. I cant refuse the work because its an area close to home and he knows what I charged for the current job and didnt seem to flinch. The problem is his house is adjacent to a wooded lot and the tree roots have migrated onto his lawn and are covering the surface of the soil. He belives this to be killing his grass. I have no idea and was wondering if this would kill the grass. And how to remove the roots and keep them removed with out cutting down the trees as he does not own the other lot. Thanks.
