Quick Answer: In the New Orleans metro area, most lawns keep growing into late November or even December because of our long, warm fall. You should stop mowing when your grass stops growing, which usually happens after a few nights in the low 50s slow down warm-season grasses like St. Augustine, Bermuda, Zoysia, and Centipede. For most local yards, the last mow of the year lands somewhere between late November and mid-December. Watch the grass, not the calendar.
Detailed Explanation
Fall in New Orleans does not work the way it does up north. Our warm, humid climate keeps grass growing weeks longer than in colder states. While someone in the Midwest might put the mower away in October, your lawn in Metairie, Kenner, or Slidell can still need a trim well into December.
The warm-season grasses that dominate our region, St. Augustine, Bermuda, Zoysia, and Centipede, all go dormant when soil temperatures drop and daylight shortens. They do not die. They simply slow down and rest. The signal to stop mowing is steady cool weather, typically several consecutive nights in the low 50s or upper 40s. Once daytime highs settle into the 60s and stay there, growth crawls to a near stop.
A good rule of thumb: keep mowing as long as the grass is actively growing and needs it. If you mow and the lawn looks barely touched a week later, growth has slowed enough to wrap up for the season. Many local homeowners find their final cut happens around Thanksgiving or in the first couple weeks of December.
Important Considerations
Timing your last mow matters more than people think. Here are the local factors worth keeping in mind.
Do not scalp the final cut. Some folks lower the blade for the last mow of the year. For our warm-season grasses, that is a mistake. Leave St. Augustine on the taller side, around 3 to 4 inches, going into dormancy. Taller blades protect the crown and roots through the occasional cold snaps and frost we get in January and February.
Our cold snaps are short but real. New Orleans rarely sees a hard freeze, but when one arrives, dormant grass with a healthy blade height handles it far better. A lawn cut too short before a freeze is more likely to suffer winter damage and come back patchy in spring.
Leaf cleanup still matters after the last mow. Once you stop mowing, fallen leaves and storm debris can smother dormant grass and trap moisture, which invites fungus in our humid climate. Keeping the lawn clear through winter protects it.
Rain and our high water table. Our wet falls and high water table mean soggy lawns. Avoid mowing waterlogged grass late in the season, since it compacts soil and tears the turf. Wait for a dry window.
