We had to have a new water line put in and where it was dug up (partial yard and sidewalk was taken up), it was all clay. It is so thick I could start making my own clay pots! What can we do to amend the soil? It is hard to even try to shovel out, and we don't know what to do with it once we are able to dig it out.
