I just bought a house last month in Wisconsin. It has been empty for a year so the lawn wasn't taken care of at all and we had the 3rd hottest summer in Wisconsin history. The snow is now gone and I can see how bad the yard looks. In some areas it looks really bad. I can see all my neighbors yards and theirs are coming in great for snow just melting.
Do I try and save it with fertilizing or do I till it and reseed? If I do decide to reseed do I need to kill the lawn before I till?
