Colorado consumers are often flooded with advertisements for zoysia grass, but the grass is not a good choice for this area.
Zoysia grass is best adapted to areas that have long, hot summers. Colorado summers are too short and the nights are too cool to allow zoysia grass to establish very effectively. It is a warm-season grass that will be green only from mid-May through early October.
Often zoysia grass is sold in small plugs that are transplanted into an existing lawn. In Colorado, the result is weedy looking because the zoysia grass does not take over the lawn. Only small patches of zoysia grass grow throughout the lawn.
