Proper mowing height is important for maintaining a healthy lawn, with recommendations differing based on grass type and seasonal changes, according to information released on Mar. 14.
The guidance highlights that cutting grass at the correct height helps prevent stress and damage, which can occur if lawns are mowed too short or too infrequently. Homeowners are encouraged to follow specific mowing heights for different types of grasses and adjust their practices throughout the year.
Warm-season grasses such as bermudagrass thrive when cut shorter, typically between 1 to 2 inches, while cool-season varieties like fescue and Kentucky bluegrass do better at taller heights around 2.5 to 3.5 inches. The advice also stresses the importance of never removing more than one-third of the grass blade in a single mow to avoid harming the turf.
Seasonal adjustments are recommended: raising mowing heights during summer helps protect roots from heat, while gradually lowering them in fall prepares lawns for winter dormancy. During spring, starting with a lower cut removes winter-damaged foliage before increasing blade height as temperatures rise.
Additional tips include sharpening mower blades regularly to prevent tearing grass, mowing only when the lawn is dry for an even cut, and changing mowing patterns each time to avoid causing the grass to lean in one direction. The release suggests that those who find it difficult to maintain optimal mowing schedules may benefit from hiring a local lawn care professional.
