Proper Mowing Heights for St. Augustine and Bermuda Grass

What Height Should You Mow Your Central Texas Grass?

Central Texas growing conditions are harsh, so every step in lawn care is important.

When its past dormancy, and you’re properly watering and caring for your grass, it’s likely growing pretty fast.  But it’s important to remember that your mowing heights need to be changed depending on the season and the type of grass on your lawn.

With that in mind, let’s go over proper mowing for two different types of grasses you might have.

Mowing St. Augustine Grass

If you’ve chosen St. Augustine grass as your lawn-type, we can’t say that we blame you.  This medium-maintenance grass is not only attractive but also good at protecting itself when its nutrient-rich cuttings are mowed out onto itself.

Remember to select a lawnmower that utilizes adjustable height and allows you to easily identify what height you have it set on.


  • Mow in March, but not too much, just the very top brown blades to allow more sun into your lawn
  • Keep the lawn at two and a half inches to three inches
  • For shady lawns, keep it between 3 to 3 1/2 inches


  • Cut St. Augustine to two and a half inches to three inches in height 
  • Leave the clippings on the grass after mowing, provided they are not accumulating to more than 1/2 inch


  • Keep the lawn height at two and a half inches until your lawn goes dormant

Your mileage may vary but in these summer months, you could be mowing about once a week to keep things in the proper zone with your St. Augustine grass.

Mowing Bermuda Grass

For those with Bermuda grass, check out some of our pro advice for cutting the lawn.


  • One inch in height is best in spring, with gradually raising the grass height leading up to the hotter weather
  • This can be adjusted to 1/2 to 1 1/2 inches for hybrid varieties


  • The best height to keep your Bermuda grass is between two and two-and-a-half inches
  • Mow Bermuda once every 5 to 7 days, which protects your lawn from disease and thatch build-up


  • Continue with one-inch height again until lawn is dormant
