Be careful. I bought over $200.00 worth of plugs from a combany and the plugs where fine. I live in a wooded area. Well in the fall two years ago I had the plugs put it and the next spring (last year) I went out side one day and there was little holes all over the place. I was freaking out, what the hack. Then the next moring I saw it. BIG, FAT GROUND HOG. I was kill that damn thing the next time I saw it and of course the next time I saw it, it had a baby with it. And I can't kill the mother and let the baby starv. So now, just two days ago. I saw that BIG, FAT GROUND HOG again. But no grass this time.
Also, if you live in an HOA you better make sure it's O.K. to plant Zoysia because it will take over the yard and if you have neighbors it will take over their yard in time.
