Hi I have owned my house for 2 years now. We bouight it in winter so when spring came and all the water we notice major swamping in the middle of our backyard and it is a big section of it. It is so bad that I can't let the kids play back there. Any tips on how to fix this that won't be so costly. I am not sure if clay would work and then replanting grass back on top or what to do , I am stuck. Please help.:( :(
