I have a problematic backyard. It's basically two inches of topsoil on top of at least two feet of clay. It's also flat as a pancake and lower than my neighbors' yards. Every spring it turns into a swamp. I need three or four days of dry weather before I can even attempt to mow it, which is not much of a problem because nothing grows there very well except nettles.
I'm planning on getting a big load of topsoil to "dome" it, but I really need to do something about the clay. They say the best thing to do with clay soil is to work "organic material" into the clay. The most readily available organic material ( that I don't produce myself! ) is mulch, basically wood chips. I would much rather go with some kind of compost. Where does one go to find a truck load of compost?
BTW, I live in SE Michigan, if that helps.
Thanks, Ven Hawkins
