A maintenance customer is looking for us to create a front yard garden bed to run along the front of their house, down beside the driveway, and across the front city sidewalk. Currently the area is a healthy stand of kentucy bluegrass. It's only about a 300sq.ft. area to be excavated but I'm wondering what'd be the easiest, most efficient way to remove the sod. Spray it with roundup then till it under? Rent a sodcutter? I don't relish the thought of doing it by hand. What do you guys suggest?
