- 1). Install edging around the garden beds. This will stop the Bermuda grass rhizomes from growing underground and then popping up in the garden soil. Make sure the edging is sunk at least 3 inches under the soil to stop the rhizomes.
- 2). Mow the lawn carefully. Angle the lawnmower so that no grass blows into the garden bed or seeds could take root and germinate.
- 3). Dig up small patches by hand. Make sure to get the rhizomes out of the soil.
- 4). Encourage the preferred grass in the lawns. Mow the grass high, about 2 to 4 inches tall, so the Bermuda grass cannot get sunlight. Bermuda grass needs lots of sunlight and cannot tolerate being in the shade.
- 5). Use an herbicide like Roundup to spot treat small areas. Vinegar also works to kill Bermuda grass and it is safe to use around children and pets.
- 6). Dispose of Bermuda grass clippings in the regular trash instead of putting them on the compost pile--seeds or rhizomes may end up back in the garden.
