Has your Zoysia started invading areas that you did not want it to? Do not worry because there is a solution! Zoysia tends to spread even once established, which is beneficial because it can heal itself. However, if the right precautions are not taken, it may spread into unwanted areas.
Round-Up herbicide is one of the easiest ways to kill any vegetation, including Zoysia. It comes in an easy spray container, and it should be applied whenever a plant is green. Remember that this product will kill anything that you spray. You should not soak the grass; only give the unwanted grass a light mist with the product. For the best results, it should be applied in a zig-zag pattern. Round-Up is rain-proof in as little as four hours, but it is still best to apply it on a sunny day.
For a non-chemical solution, you can always put a plastic or metal border at least 4-6” deep into the ground to stop the Zoysia from spreading as well. This way, you will not have to remove the Zoysia from that area because the border will prevent it from ever entering the area. Overall, there are many solutions to get rid of Zoysia in unwanted areas; however your timing determines which solution you will have to go with.
