How to Fertilize Your Lawn in Fall
Fall is the most important fertilization time for cool-season lawns (Kentucky Bluegrass, Tall Fescue). Apply a winterizer fertilizer like 22-0-14 or 32-0-10 in late October or November, after the last mowing but before the ground freezes. For warm-season lawns, apply the final feeding 6 weeks before first expected frost with a potassium-heavy formula like 5-10-15 to improve winter hardiness.
