I recently purchased a new home and have been having problems with puddles forming and soggy grass in the back yard every time it rains. The home has been in place for almost two years. There is a significant hill that slopes down into the center of the lawn where the puddles occur. I believe that low spots on the surface and hard top crust may be my problem. The builder did try to correct this problem by burying the existing lawn with only an inch or two of soil. The soil he used was horrible it was loaded with rocks and sticks. This did very little to solve the puddles and soggy lawn. I would like to try to correct this myself. Here is what I am thinking let me know if this sounds like it would work. 1. Till the problem area 6-8 deep, grass and all 2. Add screen loam and till again to mix the soils 3. grade the soil with a slope of 1ft for every 50ft away from the house 4. lightly roll the soil 5. Add more loam if necessary and level with a landscape rake Thanks for your time and suggestions.
