Honestly, I don’t want/need to. The burs are an issue all by themselves. The Bermuda is about work: DH is fed up fighting the mowing (because of gopher holes, LGD digging, mild pig rooting, etc it’s gotten to be quite difficult. We bought a new Scag zero-turn with the “extra comfy seat” this year, hoping to reduce the jarring and back pain, but it really hasn’t helped). I figured if I could find a way to “start over” with a bur-free (ok, reduced-bur), lower ground cover, it would be optimal for my marriage and the longevity of living in the country.Why do yo want to kill off the bermuda grass? It is a good grazing grass.
