I run a very short list (just google calendar invites, actually) for lawn care applications each summer. It's basically a rough guideline for putting down what chemicals and when, if that's your bag, baby. (That's totally my bag, baby.) If you're interested in this, send me your gcal email (via "karona" at youknowwhere) and I'll invite ya. The time to start it is in the next week or two.
I'm a bit of a lawn geek*, so this had started as a hobby and a few folks asked to be alerted. Maybe it's time to admit I have a grass addiction. I make no gaurantees if you are outside of the Southeastern PA area. Actually, I make no gaurantees inside that area, either, accept that I also do what I'm advising you to do, and a bad lawn makes me very crabby*.
*I may have signed up for soil temperature alerts this year.
