Improving Drainage in Clay Soil
Had the entire front yard sodded last season. I had asked the landscaping company to remove several inches of the existing soil and replace with clean soil before laying the sod as I knew that there was a lot of clay. They didn't (I fought them on this and got a substantial amount of cash knocked off the bill). As you move from the foundation toward the street, the sod gets worse and worse as the soil cannot drain. A tree in the parkway that shades the ground closer to the street doesn't help either. I considered replacing 1/3 - 1/2 of the sod (after abating some of the clay) this summer but someone told me that the application of gypsum may help to break down the clay and improve things.
