I can't dig deeper because there is a bit of concrete where I want to put it. The concrete was put there probably 30 years ago, so it is almost level, but has shifted some. I was hoping I could use dirt and sand to level the edges, but I think I need a better level. Maybe a straight board that is about 3ft long that I could scooch (IT'S A WORD) around in a circle to smooth it all out. idk.
