A sharp blade is key to a clean, even cut. Dull blades tear grass rather than cutting it, leaving behind unsightly brown tips and increasing the risk of disease. Sharpen your blade regularly, especially before each mowing season.

Mow at the Right Height

The height at which you mow will affect the health and appearance of your lawn. For most grass types, the ideal height is between 2.5 and 3.5 inches. Mowing too short stresses the grass and makes it more susceptible to weeds and pests. Mowing too high can block sunlight from reaching the lower blades, leading to a thin, weak lawn.

Mow in Overlapping Rows

To avoid missing any spots and ensure an even cut, mow in overlapping rows. Start at one end of your lawn and mow in straight lines, overlapping each previous row by about a third. This will help to evenly distribute the cut grass and prevent scalping.

Alternate Mowing Directions

To prevent soil compaction and help your lawn grow more evenly, alternate the direction you mow in each time. This will help to distribute the weight of the mower and prevent ruts from forming.

Leave Grass Clippings on the Lawn

In most cases, it is beneficial to leave grass clippings on the lawn. Clippings provide nutrients for the soil and help to retain moisture. They also act as a natural mulch, helping to suppress weeds and keep the soil cool. However, if your lawn is particularly thick or lush, you may need to remove some of the clippings to prevent thatch buildup.

Mowing Height Ideal for Grass Types
2.5 – 3.5 inches Most cool-season grasses, including Kentucky bluegrass, fescue, and ryegrass
1.5 – 2.5 inches Fine-textured grasses, such as bentgrass
3.5 – 4.5 inches Warm-season grasses, such as Bermuda grass and St. Augustine grass
