I just planted my whole yard with Kentucky blue grass seed. I airraided the yard then spreed the seeds and watered everyday for about 10 - 15 minutes and withen about two weeks my yard looks great. I was very surprised since I just cut down 26 pine trees which makes the ground have a lot of acid. It looks a lot better than I expected. I am going to fertilize this week. Then this fall I will airraid again and re seed the yard again just to take care of a few bald spots. I had tried to seed the yard a few times in the last few years using cheep stuff from K mart/walmart however nothing ever happened. This Kentucky blue grass is working great. I live in VA though.
