Learn why it’s important that your grass is maintained at its ideal height.

No matter what grass you have on your property, every type of grass has an ideal mowing height. Maintaining your lawn at the right height is very important, and is the best way to keep your grass healthy and lush. Continue reading to learn about the ideal height to cut your grass.

Not Too Short, Not Too Long

Have you heard the saying that the shorter you mow your grass, the less often you’ll have to cut it? This is actually a myth, as grass that is too short is more likely to be harmed by weeds, drought, and heat damage.

On the other hand, grass that is too long is also damaging to your lawn. If you don’t cut your lawn frequently enough, your long grass may become the perfect habitat for insects, small critters, and snakes. Also, long grass is hard to mow, and your lawn will likely need to be raked or bagged, creating a long process. Rather than going through all that work and grass damage, it’s much easier to mow frequently enough for your grass to maintain its ideal height. The frequency of which you mow your grass depends on your grass’s ideal height, which varies during the growing season. Most lawns don’t need mowing more than once a week, even during peak growth.

Cool Season Grass

Since Maryland has extreme summers and extreme winters, lawns throughout the state are split between warm season grasses and cool season grasses, while some lawns have a blend. Cool season grasses generally perform better when cut higher, but the specific heights will vary among different types of grass. In general, their ideal height range is about .75 to 4 inches high.

  • Fine fescue: 1 ½ to 4 inches
  • Kentucky bluegrass: 0.75 to 3 ½ inches
  • Perennial ryegrass: 0.75 to 2 ½ inches
  • Tall fescue: 1 ½ to 4 inches

Warm Season Grass

Warm season grasses achieve peak growth in the summer, and their ideal heights will vary by region. The ideal heights for these grasses also have a wide range depending on the type of grass, from .5 to 4 inches.

  • Bahia: 2.5 to 4 inches
  • Bermuda: 0.5 to 2.5 inches
  • Buffalo: 1.5 to 4 inches
  • Centipede: 1 to 2.5 inches
  • Kikuyu grass: 1 to 1.5 inches
  • St. Augustine: 1 to 3 inches
  • Zoysia: 0.5 to 3 inches
