Your Last Mow of the Season: How to Know When to Stop (and What to Do Before You Park the Mower)

The leaves are falling, the mornings are crisp, and you're starting to wonder: is it finally time to put the mower away? Not quite yet. The last few cuts of the year matter more than you might think, and getting them right sets your lawn up for a stronger start next spring.

So, When Do You Actually Stop Mowing?

There's no magic date on the calendar. Your lawn tells you when it's done. Grass stops growing when temperatures drop, and a good rule of thumb is that mowing ends once growth stops, usually after your first hard freeze or when daytime highs stay in the 50s.

In Dallas-Fort Worth and Atlanta, that might not happen until late November or even early December. In Nashville and Charlotte, you may be done by mid-November. Up in the Greenville-Spartanburg foothills, it can fall somewhere in between. Don't mow by the calendar. Mow by the grass.

Here's a simple test: if you can still see the grass blades visibly gaining height a week after a cut, keep mowing. If it looks about the same, you're likely finished.

Warm-Season Grasses: Bermuda and Zoysia Head to Bed

Bermuda and Zoysia are going dormant right now, and that's perfectly normal. As the days shorten and nights cool off, they slow down, turn tan or straw-colored, and stop needing regular cuts.

For your final mow or two, you can drop the height slightly, about a half inch lower than your summer setting. For Bermuda, that often means around 1.5 to 2 inches, and for Zoysia, around 2 to 2.5 inches. A slightly shorter cut helps clear off the last of the leaf litter and dead growth, and it keeps the lawn tidy through winter.

But don't scalp it. Cutting dormant grass down to the dirt exposes the crowns to cold and invites winter weeds like henbit and chickweed to move in. Lower is fine. Bare is not.

Tall Fescue: Keep Going a Little Longer

If you have Tall Fescue, you're on a different schedule. Cool-season grasses love fall weather, and your lawn may still be growing strong into November, especially if you aerated and seeded this season.

Keep your mower set to a taller height, around 3 to 3.5 inches, for most of the fall. On your final mow, you can come down to about 2.5 to 3 inches. That's short enough to prevent the grass from matting down under leaves and snow, but tall enough to protect the crowns.

If you recently overseeded, wait until new grass is at least 3 to 4 inches tall before its first mow, and make sure your blade is sharp so you don't tear up young seedlings.

Park Your Mower the Right Way

Once that final cut is done, give your mower a little love before it goes to bed for the winter. Future you will be grateful in March.

- Clean the deck. Scrape off caked-on grass and debris to prevent rust.
- Sharpen or replace the blade. A sharp blade makes a cleaner cut, and winter is the perfect time to do it before the spring rush.
- Handle the fuel. Either run the tank nearly empty or add a fuel stabilizer so gas doesn't gum up your carburetor.
- Change the oil and check the air filter. Quick wins that keep things running smoothly.
- Store it somewhere dry. A garage or shed beats a rainy side yard every time.
