The picture to the right shows a Zenith Zoysia test site.
A strip of Zenith grass was planted in a cool season lawn, which is our familiar rye, fescue and bluegrass.
The picture was taken during a July dry period. We can see how green and healthy the zoysia grass is compared to the surrounding cool season grass that has browned due to heat and drought stress.
Here, two lawns are shown. The top picture shows a cool season lawn that is turning brown due to lack of rain.
The bottom picture shows a zoysia lawn. We can see the zoysia lawn stayed green under the same drought conditions.
