This is my situation. A little bit more than half my back yard is grass less. This is because of a raised flower bed and pool. They have both been removed. The rest of the yard has some nice area of grass and other areas where you can see the ground in between clump of grass. I just had all of the dirt hauled away from my back yard which left two nice big tractor impressions in the grass. They are about a foot deep and are raised up on the sides with dirt tracks in between. I dont have the money to just resod the whole yard. So I was told that the first thing I need to do is get a roller and roll the yard where the tractor drove back flat. Then fill in the tracks with some nice fill dirt and get the ground back to level. Next step is to rent aerator and aerate the whole back yard. After that rent a thatcher and thatch the whole back yard. At this point they told me reseed and over seed the whole back yard including the two places where there is no grass at all. Then fertilize and begin to water it like crazy. Is this on the right track or should I do something else? Thanks for the help.
