When Is the Last Lawn Mow of the Year?

The temp is finally starting to cool down, and you can feel that crisp autumn breeze in the morning. You may be wondering, “How in the world is my lawn still growing?” It’s getting close to the last mow of the season, but that timeframe varies by location and by year. Read on to learn when you should plan your last lawn mow.

Mow before the First Frost of the Year

It’s best to mow your lawn shortly before the first frost of the year. You can check the Almanac frost predictions for your local area to get an idea of when the first frost might hit you. Plan to mow a couple times before that day, reducing the blade height each time. In most cases, the first frost will hit some time in late October or in the month of November, occasionally dipping into early December.

When Does the Grass Stop Growing?

As long as the weather is relatively warm, the grass will continue to grow. Once temperatures consistently drop below 50°F, that’s when the grass stops growing. Again, this may vary by year and location, depending on the rainfall in the area and other factors.

How Short Should I Cut Grass for the Last Mow of the Year?

Your grass should be between 2 and 2.5 inches tall for the last mow of the year. This provides enough turf to not stress out your lawn during the cold weather. If the grass is too tall, it may lead to snow mold in the winter months. Too short, and it will have a hard time bouncing back in the spring.

As a general rule, don’t cut more than one third of the grass height every time you mow. If your grass is 3 inches tall, you’d cut off a max of 1 inch. If you need to get your grass shorter for the winter, taper down the height over several mows.

End-of-Year Lawn Care Checklist

The last lawn mow of the year isn’t the last landscaping task. Make sure to complete these other end-of-year lawn care steps to protect your landscaping through the winter:

  • Clean out the gutters
  • Rake and remove leaves, and keep leaf piles away from your fence line
  • Winterize irrigation lines
  • Remove water from outdoor fountains, hoses, or anything else that holds water
  • Wrap shrubs with burlap for the winter to prevent sunburning in the spring
  • Clean up the last remaining weeds to give your garden a fresh start next year
  • Top off mulch
  • Fertilize, as needed
