I was concerned that the product would be "stale", but I found that its germination was tested nine months ago ... giving me confidence that my efforts wouldn't be wasted. As seeds go, the germination and noxious weed content was above average. While it "came up" in 10 days as advertised, haven't yet had a good look at the grass. But from what I've seen, I think I'm going to like it. Next three weeks will tell.
