I recently bought a house in Central Missouri. My lawn was horrible. There
were humps, holes, bare spots, etc. I've been using Ortho Weed B Gone, to
get rid of all the leafy stuff. I've pretty much got the weeds under
control, now I'm working on the moles.

My question is this: I have what seems to me as several kinds of grass in
my yard. What I DON'T know about grass could fill a thick book. How many
kinds of grass are there? What do I have to do to get an even looking yard?
I want it all the same shade of green and nice a thick. I wanna walk
barefoot and feel like it's carpet. I can't imagine I need to till
everything up and replant grass. Or do I? Do I need to fertilize or what?

Advice?
