When to Apply Fall Fertilizer to Your Lawn
Apply fall fertilizer in September for the main feeding and late October to November for the winterizer. For cool-season grasses, the September application is the most important of the year, it fuels root growth and nutrient storage. The winterizer goes down after the last mowing, when top growth has stopped but roots are still active. For warm-season grasses, the last feeding should be 6 weeks before first frost.
