planting lawn over stump grinding
Removed old silver maple and had stump and root grinding done. The stump and lateral root area that was ground covered approximately 900 square feet. i am currently digging the sawdust and ground root material to a depth of about 8 inches. i am then sifting out all the root material and discarding. My wife hired a landscape contractor and he just spread all the material and compacted it down. His plan is to add tops top of the compacted soil. Is this correct ? Or is it correct to remove all the stump and root material ? If topsoil is added what would be the correct depth ?
