Is it safe to put grass seed down now, we have had a couple of frosty mornings but I need to get some grass in my field/garden, I'm getting married in the garden toward the end of the year and I need some established lawn, quality isn't important, like I said its a field/garden, a bit of a wild garden in a Field up the road that we acquired for our dogs, it will be a tough grass or the dogs will just churn it up.
