Someone help me out here... I'm going to be installing a plan that calls for two small bed areas, in places that are presently covered with dormant bermuda grass. So... what do I do? Can't use roundup to kill it... Dig it up and haul off the soil, and bring in new topsoil? How deep would I have to dig it out to be sure to get all the rhizomes? Or is there another way of doing this that doesn't involve digging it up? I can't wait for it to come out of dormancy, that's over a month away and the client has made a decision about it NOW.
