Many universities offer online classes to teach you just this sort of thing. Look for Turfgrass Management or similar. It's worth the time and money. You'll learn lots of info that you wouldn't even think to ask about. Take fall classes. You won't be as busy through the winter and by spring the classes will be over.

You can also go to your local supplier (JDL or others) and they can help you set up a yearly program. Its a start.
