I went by today and look at a new account for this year. The lawn is Emerald Zoysia that was laid last March. A few areas in the lawn didn't grow very well last season and the growth is spotty. I talked to the homeowner about replacing these areas, and they wanted to just let it fill in on its own. This will be my first lawn with EZ and was wondering how fast EZ spreads? Most of the growth is spaced about 4 inches apart. Thanks.
