How to Landscape Grass to Soften a Stone Bench

Select a suitable bench. The surface must be flat and uniform to allow for the grass to be laid on top of it evenly. Look for one with a rim around its seat surface in order to hold the soil in place and prevent water, soil and sod from draining off of it completely.

Drill some drainage holes through the stone bench. Without some opportunity to drain water, the grass will quickly become soggy. Use a hammer drill and a concrete drill bit to make drainage holes of about 1/4 inch in diameter through the seat surface of the bench to allow excess water to seep and drain through. Space these holes about 4 inches from each other.

Lay a bed of triple mix soil over the bench. Spread the soil evenly and lightly pack it to the seat surface of the bench. Pack between 2 and 4 inches of soil onto the bench seat, ideally held in place with by a rim around the perimeter of the bench. If the stone bench does not have a rim, taper the soil to the edge.

Lay a roll of sod over the soil applied in step three. Trim the edges using a trowel to make clean and straight lines around the perimeter of the bench. Water the sod and bench immediately after the application of the sod to help integrate the sod with the new soil. Do not sit on the bench for at least one week to allow the roots of the sod to take hold in the soil.
