Proper Mowing Heights for St. Augustine, Bermuda, Buffalo and Zoysia 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.

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

With that in mind, let’s go over proper mowing for four different types of Central Texas grass.

Mowing St. Augustine Grass

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

Spring & Summer

  • Mow in March, a notch or two shorter than you normally do to get rid of dead material (this allows the lawn to come out of dormancy faster)
  • Keep the lawn at 2.5″ to 3.5″
  • For shady lawns, keep it between 3″ to 3.5″
  • The mowing frequency will vary throughout the year based on rain, but you can expect to mow about once a week

Fall

  • Keep the lawn height at 3″ until your lawn goes dormant

Mowing Bermuda Grass

Bermuda grass is tolerant to both high-traffic and drought, making it an excellent choice for Central Texas. According to Texas A&M Co-op Extension, it grows “best under extended periods of high temperature, mild winters and moderate to high rainfall.”

Spring & Summer

  • Mow in March, a notch or two shorter than you normally do to get rid of dead material (this allows the lawn to come out of dormancy faster)
  • Keep the grass at 1.5″ to 2.5″ in height, gradually raising the grass height leading up to the hotter weather
  • Mow Bermuda once every 5 to 7 days, which protects your lawn from disease and thatch build-up

Fall

  • Continue around a 2″ height until the lawn is dormant

Mowing Buffalo Grass

Buffalo Grass is s a low-maintenance prairie grass and has less risk for lawn disease. It looks best (and is healthiest) in its natural state…nice and tall.

Spring & Summer

  • Mow in March, a notch or two shorter than you normally do to get rid of dead material (this allows the lawn to come out of dormancy faster)
  • Keep the grass at 4″ to 6″  in height
  • Mow Buffalo once every 2 to 4 weeks

Fall

  • Continue around a 5″ height until the lawn is dormant

Mowing Zoysia Grass

Zoysiagrass is another drought-tolerant option but requires regular dethatching.

  • Spring & Summer

    • Mow in March, a notch or two shorter than you normally do to get rid of dead material (this allows the lawn to come out of dormancy faster)
    • Keep the lawn at 2.5″ to 3.5″
    • For shady lawns, keep it between 3″ to 3.5″
    • The mowing frequency will vary throughout the year based on rain, but you can expect to mow about once a week

    Fall

    • Keep the lawn height at 3″ until your lawn goes dormant
