My front yard is hard clay. I have an idea, what do you think of it? I would aireate the yard well. Then I would buy bags of topsoil and mix it with with water so it is fairly runny (not just muddy, but liquidy). Then pour that over the soil to get it down into the holes. Would be some work but it seems like a good idea, would it work? I would have to do it several times. Or would just pouring sand over the top be better and easier? Thanks!
