I'm in the Chicago area (KBG, rye, fescue). I put down 1 pound of N per 1,000sf in September. However I have been getting conflicting answers from suppliers and extension offices regarding winterizer. I have always used 10-1-10 (.4 pound of N per 1,000sf) in November with good results. However, I've also heard that using more N with quick release is best. What do you use and why?
