Installing stone patio over maple tree roots
We are thinking of installing a small (10'x10' or so) stone patio about 4' away from the trunk of a mature sugar maple tree. Most likely, we'd build a small retaining wall and lay the stone in a gravel/sand bed.
My concern is twofold: harming the maple and having its shallow roots dislodge the stones.
Another option would be to build a very short wooden floor.
What do you all think?
Thanks in advance,
