I can't seem to locate a landscaper who knows about zoysia lawns and the maintenance of it. They just cut the lawn. I had a beautiful lawn this spring. Now I have brown patches and weeds have taken over. Not sure if it's from the weed killer they put down in July. Before that I just had weeds but no brown patches. And I still have the weeds also.
