Too Late for Fertilization?

I skipped an application of fertilizer in the summer and put down Scott's Winterizer in mid October. It's obvious that the fertilizer is all depleted and the green grass starts fading. My question is: is it too late now if I put down some more of the fertilizer since the leaves are not growing. Would it at least help the roots?
I live in central NJ and the weather is unseasonably warm right now.
