We have a dog. She p***ses in the same place every time, its always one of the 4 corners of the lawn. She is away for a week and I have some new turf to put down (have laid it out flat on concrete and watered it for now). I wanted to know what is the best way to repair the bare ground where it is "contaminated". Would it be best to dig out a load of earth and replace with clean soil? Or will the turf take to the contaminated soil?
