When to Stop Mowing Lawn in Fall: Your Last-Mow Guide
Time your final cut by growth, not the calendar: for most cool-season lawns that's late October to mid-November, once a few hard frosts slow growth to under an inch between cuts. Finish at 2 to 2.5 inches, shred or remove fallen leaves, and spread out snow piles so matted, soggy grass never gets a chance to grow fungus. If patches still show up in spring, rake them gently, hold the fertilizer, and reseed only what stays brown after three to four weeks of warm weather.
