Bermuda and St. Augustine grasses are similar because they are both warm-season, rapid-growth grasses that are found throughout Florida, Texas, Mexico and the Southern United States. Because both grass types grow rapidly, it is sometimes more desirable to eliminate them from your lawn to replace them with a lower-maintenance grass. Getting rid of Bermuda and St. Augustine grasses will take a couple of weeks to accomplish, but it is a simple process that does not involve expensive materials or specialized skills.
Hand-pull patches of Bermuda and St. Augustine grass you wish to eliminate from your lawn.
Dispose of pulled grass patches into plastic bag or compost bin.
Spread old newspaper over the remaining patches of Bermuda and St. Augustine grasses in your lawn.
Weigh down the spread newspaper with bricks or heavy weights and leave in place for two weeks.
Remove the old newspaper from the Bermuda and St. Augustine grass patches and spot check the area to ensure no new unwanted grass has grown. Hand pull any new Bermuda or St. Augustine grass growth and spot check the area on a weekly basis until all St. Augustine and Bermuda grasses have been eliminated from your lawn.
