Most lawn experts say taller grass stays healthier, but when winter nears, many wonder if that final mow should be shorter or left high. Experts recommend mowing your lawn higher (around 3 inches) and cutting only a third of the blade at a time for the healthiest growth. Keep mowing until grass growth fully stops in late fall. Growth can continue surprisingly late, sometimes even into December in cooler regions. Regular mowing promotes dense, healthy turf and keeps your lawn's surface even. Skipping late-season mowing can leave your lawn uneven and harder to manage next spring. For the final mow, slightly shorter grass can help reduce snow mold and keep things tidy, especially in snowy climates. However, mowing too low can damage roots, particularly in warmer regions where grasses differ and snow mold is less of a concern. After frost or freezing, avoid mowing or walking on your lawn to prevent lasting damage and potential plant loss.
