For reasons too lamentable to mention, I want t0 completely to renew my 60%-creeping-buttercup lawn. So I really need to get rid of every living thing there. Everything I read has spraying herbicides as step two 2 or 3. Probably illegal but anyway, not for me. A few "natural" sites say spraying with a powerful vinegar is an alternative. A myth: it does not have even the slightest effect on anything. I could buy turf but I doubt that one can simply place it over a bed of weeds and get good results. I guess I'll have to rototill the whole thing. But first - does anyone here have another suggestion?
