How to Kill Grass in Ground Cover

By Melissa Lewis ; Updated September 21, 2017
Keep grass from growing in your ground cover.

A ground cover, such as a creeping juniper, is a practical alternative to grass. It grows and fills in a space and often has blooms that are aesthetically pleasing. In addition, a ground cover works well on slopes where mowing is often difficult, and acts as an effective erosion control. Sometimes though, before the ground cover has filled in an area, grass grow in the bare spots, competing with the ground cover for water and growing tall and unsightly. Fortunately, eliminating, killing and preventing the grass from growing is fairly easily.

Pull out the grass, which is easiest when the soil is moist. In larger areas, you can loosen the soil with a hoe to help in this process. Be sure to get up as much of the roots as possible.

Spray an herbicide designed to kill grass. Follow label directions, but usually you spray it directly on the grass and apply a second dose one week later. Do not use the herbicide within an hour of an expected rain and always check the label to be sure your specific ground cover will not be affected.

Apply a 2- to 4-inch layer of mulch, such as pine needles or bark mulch, after you have pulled the grass out or after it has died from applying an herbicide. As your ground cover continues to grow, fill in and shade the empty space, the mulch will help prevent grass from growing again.
