Hello, this will be my second year in the mowing biz, and i really feel i should dedicate this next month and a half to studying up on turf. to be honest i really don't know enough about it as i should. i was wondering if anybody out there has some good suggestions as far as good reads to get me studied up for the spring. i want to be able to answer my customers' questions about their lawns, and actually know what i'm talking about. of course even if they don't ask questions i should still know everything about grass in order to give them a nicer looking lawn. Thanks in advance!
