If you don't have any snow cover, and you want to provide some fertilizer try something organic like Dry Roots, or Espoma Organic. Don't put down anything that is all chemical (straight fertilizer) during the winter, because the nutrients will more than likely run-off before being absorbed. You can use something like this later, in early spring, by itself, or with a pre-emergent if crabgrass is a problem. The organic sources of nutrients (including NPK and micro-nutrients) are, in my opinion better now because they will stick around longer in preparation for the spring. We put down the dry roots before rolling out sod here in Connecticut. Sometimes we use a 12-22-18 Starter w/iron and micronutrients that I have custom blended.
