Most Champaign lawns are nearing their final mow of the year, which is when winterizer timing comes into play. University of Illinois Extension says a winterizer fertilizer is optional and, if used, is applied one week after the final mowing. The main feeding for Central Illinois lawns is August 15 to September 15.
