OK - for guys with northern turfgrasses only.... What is your product of choice for 1st round (fert + pre, pre only, etc). AND Why do you keep going with it year after year OR why are you switching it up this season? I have been using 17-0-0 with .28 prodiamine and while I am fairly satisfied with crab control, the fert end of things just does not provide a super quality green up. I realize some of the green up may be dictated by what is applied late fall, so perhaps that is my issue??
