I have to do a renovation. The topsoil, sod, and maybe a retaining wall, plants, etc. is no problem. The problem is the tree root above the ground. This guy wants sod, no bed, there. My suggetsion was to remove the tree AND the roots (if possible). It is pine(s), so the roots should not be too deep. Other option, cover the roots and lay sod. How can I cover the roots with dirt w/o smothering the pine? Or can I? What do you guys think? I can provide more information is needed.
