Guys/Gals, I am a homeowner. I just took out all my old grass with a sod cutter and then tilled the back yard with some topsoil and peat. I tilled between 4-6 inches. The ground is very very soft and mushy when I ran the sprinklers today. I have sod coming in about a week, I do not want to install on soft ground, or can I do it and just stay off of it for a few weeks and will it harden up? I already used a lawn roller on it in three directions. I just do not want to put down sod and then 2 weeks later go to mow it and have my foot going through into the soft soil. Any ideas or solutions would be great. Thanks in advance.
