Hi, Barb: Well. Sounds like you have quite a battle on your hands! This is a little difficult to answer because we don't know where you are, how big your yard is, whether you're near neighbors susceptible to plant invasion, why your yard is muddy (drainage, we assume), what your sun/shade is like, and so forth. If it were us, we would do a test on a part of the lawn to try out clover as a ground cover. Level and amend the soil so that it is 1:1:1 topsoil:sand:clay; doesn't have to be too deep--4 to 5 inches is fine, scratch it into whatever is already there. Then try white clover mixed with a tough grass seed (ask at a nursery), 1:3 clover:grass. Try consulting with your county/state extension service on this, too, as they might have more localized advice. Most of all, don't be afraid to experiment. Fence off a couple of test areas at a time if you can. You can win!
