We live in Southern California and two weeks ago we planted marathon I sod in our front and back yard. The back yard is very nice, but the front yard feels very wet and muddy beneath the grass. We have sprinklers with a timer and have watered as we were told. My husband says there is no leak on the sprinklers. My husband did not use a roller over the dirt and after the sod was planted - could this be the cause? the back yard is fine and he didn't use it there either. Please help - I have a big event in a couple of weeks and there is no way we can walk on it the way it is now!!!!!
