So When Should I Apply Weed & Feed?

So I understand the box store crabgrass preventer + slow release N is not considered the right way to go for either purpose, but I have a bag of it and should use it up. I'm thinking that since I applied several N apps in the fall and late fall, I should be OK and time the crabgrass preventer for optimum kill of the little bastards. Lawn is greening up quick around here (NE Iowa) and will need mowing in a week or so. When is the best time for granular app for crabgrass control?
