Having 6.5 acres I just cannot avoid grass. The alternative to grass is labour. I already have too many gardens (half of my property is wooded tho so that's ok). But I have no interest in "lawns". I just "let" a lot of clover, creeping charlie, plantain etc grow. Or rather, I make no effort to maintain it other than mow. So I just try to be strategic about when I mow to avoid toad and bee death.
