In the last year a section of my yard on a slope has got where it WILL NOT dry up. When I walk on it its mushy and just really wet. I can dig down 6-7 in and the soil is soaked it seems like. Before the fence it was nice and had some of the best grass in the yard, but since the fence went up a little over a year ago it has gone to crap. After the lack of sun really thinned out the grass, Moles moved in really tore/rutted the ground. I guess from me walking on it every day just made it worse. When I don't get at the bottom of the hill/slope the ground is fine and dry. Any ideas what I can do? Its been multiple days of hot weather and no rain with no change. Its not just the part with no grass, it extends out into the grass 2-3 feet, and those parts get PLENTY of sun. Right now its early in the AM and the sun isn't't hitting them, but later it does except for the closet part to the fence. Its only on the sloped part too in that one 20 ft stretch, rest of the yard is great. Instead of trying it grass again next to the fence the wife wanted to plant some ground cover so I let her have at it. In the last pic, its mushy 2-3 feet into the grass and for 10 or 20 feet towards the house. I don't think its the fence because since the ground is fine next to the house and gate and fence by the house, its only here near the back.
