I have a customer that wants me to extend her beds, add about 3" of top soil and add mulch. There is about 35 - 40 sq. ft. of sod that needs to be removed to make the kidney shaped beds she wants. What is the easiest way for me to do this? Do I rent a sod cutter and take it out that way. I'm sure as hell not going to cut it up with a spade and take it out by hand. If I spray with round-up, can I just add the new soil and mulch on top of the existing grass? I am just a one man operation and I want to get this done as quickly and as efficiently as possible. Any suggestions would be helpful. I tried a search but could not find what I was really looking for.
