How to Stop Zoysia From Creeping Over Sidewalks
Zoysia are hardy warm-weather grasses that are often used in lawns. A lawn with Zoysia grass is green and lush when it's not dormant during the cooler months. Zoysia grasses are aggressive and will spread quickly over a sidewalk once they are established in a lawn. Compounding the problem is the fact Zoysia grasses spread sideways--as opposed to up. Stop Zoysia grass from spreading by installing a barrier along the sidewalk. Does this Spark an idea?

Other edging materials such as wood are also available, but it's better to use something that won't rot (or deteriorate) underground. Make sure edging is at least 8 inches high.

Tips & Warnings
You can also initially remove Zoysia grass from the area next to the sidewalk with a herbicide. This helps prepare the area to install the edging, but won't do anything to prevent the Zoysia grass from coming back.
