What is the best way to get some bona fide "Turf Knowledge"? I am talking strictly about turf(grass) whether it be books you reccomend, classes, websites, tutors or whatever else. I am not talking about the stuff you learn from experience. I realize that can only be learned through experience. I just wanna better myself at this and believe I should start learning about it, but am not sure how to go about it. I will eventually learn about everything else, but for now my main concern is "Turf Knowledge". All help is already appreciated!!!!
