Empire Zoysia Sod not Greening
March 2009, my landscape company installed Empire Zoysia sod. Every piece of sod they used was brown and I was told that it would green up when the weather got warmer. By May, only 50% of the lawn is green and it looks horrible. I believe he installed damaged sod in my yard. Should I ask him to replace the Empire sod immediately or wait and see if it greens up by July?
