Zoysia grass is a warm-season, drought-resistant grass commonly found throughout the Southern United States. Because zoysia grass is considered low maintenance, it is often popularly chosen over rapid-growth grass such as Bermuda grass. Bermuda grass is also known as the sports turf of the South, and is frequently chosen for sports turf such as football fields and golf courses. Bermuda grass patches can be suppressed easily from your zoysia grass lawn without the need for specialized skills or landscaping professionals, all you'll need is a little bit of time and some old newspaper to get the job done.
Hand pull patches of Bermuda grass you wish to suppress from your zoysia lawn.
Dispose of Bermuda grass patches into plastic trash bags or compost bin. Ensure that remaining Bermuda grass patch is of an even height (no higher than 5 inches), as this will help successfully suppress any remaining Bermuda grass in your lawn.
Spread old newspaper over the remaining Bermuda grass you wish to suppress.
Weigh down the newspaper with bricks or heavy weights and leave them on top of the newspaper for a period of two weeks.
Remove the newspaper and bricks after two weeks have passed. The newspaper blocks sunlight that Bermuda grass needs to survive. Spot check the area to ensure the Bermuda grass has been suppressed sufficiently. Check the new growth on a weekly basis to continue to suppress any unwanted Bermuda grass in your zoysia lawn.
