The neighbor had zoysia sod installed several years ago. It is putting-green beautiful in the summer. But...starts fading out in the Fall...is paper-bag brown by winter....then starts greening up again in Spring. And, incredibly invasive. I built a low landscape block wall to separate our yards...put a planting area with a 2-foot kill zone along the block wall. Anything green in that kill zone is Rounded-up. I should’ve done the same thing on the opposite side. That neighbor has a healthy supply of Bermuda...and it loves MY yard.
Nuke it from orbit....
