I have two pine trees that are about six feet away from the back of my house. I would guess they are about 30' tall. The problem is that over the years the ground between the two trees has raised up above the grade causing water to run back toward the house. I tried digging some of the dirt out between the trees, but there seems to be a lot of roots right below the surface. I thought about using a rototiller to break up some of the roots, so I can correct the drainage. Does this sound feasable?? I don't want to screw up the rototiller. I really am not too worried about the tree. I wouldn't mind having them cut down and rooted, but I am not sure if I could afford it. Anyone have a general idea what it would cost to cut down two pine trees about 30' tall with a trunk diameter of a 1'?
