gray patches in zoysia in yard.
I have zoysia in yard. There are some brown patches that have been showing up at one side of house. What could this be?

Given the time of year, this could just be zoysia's natural tendancy to go dormant in cool weather. This results in large brown patches in the winter months. If the brown patches do not regreen in the spring, then it is a funus and you will need to treat the lawn with a fungicide.
