I would give this a 5 star except I have to consider the effort it takes. This seed makes a beautiful low maintenance lawn but getting it started is a great deal of time and planning. you must follow the instructions and water water water until it is established.
The rating is not a reflection of the product per se, but of the difficulty of having it work in mostly shaded areas (big trees) here in South Carolina. The seeds have (mostly) sprouted, about (66% gestation), but they're staying put and not spreading as we'd hoped. So we're getting Zoysia patches (rectangular sod pieces) for the bare spots. It's just a bit disappointing at present.
