How High Should You Mow Your Lawn in Tennessee?

A lot of people think a short cut looks cleaner and means they can mow less often. But cutting too short is one of the fastest ways to get a thin, weedy, brown lawn. The right height depends on your type of grass.

Know your grass

Most lawns around Cleveland are tall fescue. Some sunny yards have Bermuda or zoysia, which spread out and turn tan in winter. If you're not sure, text us a close-up photo and we'll tell you.

The right mowing height

  • Tall fescue: 3 to 4 inches
  • Bermuda: 1 to 2 inches
  • Zoysia: 1.5 to 2.5 inches

Follow the one-third rule

Never cut off more than one-third of the grass blade at one time. If your fescue is 6 inches tall, bring it down to 4 inches, then cut again a few days later. Cutting too much at once stresses the grass and can turn it brown.

Why taller is better in summer

Taller grass shades the soil, keeps it cool, and holds water longer. It also blocks sunlight from weed seeds, so fewer weeds sprout. In July and August, raise your mower up a notch.

Keep your blade sharp

A dull blade tears the grass instead of cutting it. Torn tips turn brown and invite disease. Sharpen your blade at least once a season, or twice if you mow a big yard.
