My lawn is in its 3rd year now and I really need to put some time into it. Here is what I have. When the house was built they tore up most of the yard, but left the last 100 feet alone. It was weeds and long grass. I have been maintaining it for a few years, but it is sooooo thick that when I mow, I always have to rake. The other planted grass is ok, but fairly thin. I have a ton of thatch in the thick part. What should I start to use this year to put on the yard? My neighbor's lawn is great and he fertilizes monthly. I guess I need some advise on what to put down or what to do first, second, etc. Thanks in advance.
