When is a good time to put winterizer down in Raleigh,NC? I basically have been using organic ferts(Alfalfa pellets, and most recently Espoma Organic Lawn fertilizer). I put down the Espoma in late september, and planned another application in late october. I was thinking it would be a good time to put down winterizer in mid-late november. Does that sound about right? Do I even need the winterizer? I believe the Espoma is 18-6-8, or 18-8-6. Thanks for your input.
