How Short Should I Keep My Grass?

We have probably wondered, “How short can I cut my lawn without damaging it?” The answer, of course, is conditional on things like the type of grass, the season, and the frequency with which you mow your lawn in Salt Lake City. Most lawns benefit from a mowing height of 3 to 4 inches for cool-season grasses and 2 to 2.5 inches for warm-season grasses. The roots of your grass will be protected from the scorching sun by the cooler soil at higher heights throughout the warmer months. Here are some things to remember if you want your grass to look beautiful and flourish all year long. 

Grass Varieties and Heights  

Depending on the sort of grass you have, even if you only raise or lower the lawn by an inch or two on occasion, you might be seriously damaging the grass’s general health. Getting to know your lawn by name is crucial because various types of grass have distinct requirements. Kentucky bluegrass, perennial ryegrass, creeping bentgrass, and tall fescue are all examples of cool-season grasses that thrive in cooler climes. To protect the soil and the roots from heat, they should be cut to a height of around 4 inches. Warm-season grasses, including Bermuda, centipede, and zoysia, are best maintained at a height of around 2 to 2.5 inches in the warmest climates.  

Don’t Steep it Too Much 

Some people choose to mow less frequently by keeping their lawns shorter. Mowing the grass excessively short, regardless of how appealing it may seem, can really be harmful to the lawn’s health. Mowing at too short of a height puts unnecessary strain on your grass and can cause the density of your grass to thin out, making your lawn an inviting environment for invasive weeds. Sunlight is essential for the development of lawn weeds like crabgrass and foxtail. Cutting the grass too short allows more sunlight to reach the soil, which in turn encourages the growth of weeds. However, when the grass is allowed to grow to a greater height, it blocks out more sunlight, making it more difficult for weed seeds to grow. The longer the grass, the better it can compete with weeds and protect itself from the damaging effects of the scorching summer sun. 

One Third Rule 

Never cut more than a third of the grass’s height in a single mowing, regardless of your grass type. Why? We tend to overlook that grass is a living organism that suffers trauma from being mowed. When you know the appropriate height for your lawn, you can prevent stressing out the grass by not removing too much of it. Then, wait until it’s one-third longer than necessary before cutting it. 

Mowing Frequency  

Cutting grass too short encourages weed growth, dryness, and heat damage. But if you let your grass grow too long, you can invite mosquitoes and other pests into your yard. How do you decide how often to cut the grass, given all these variables? You may only need to mow once every five or seven days, even though many people adhere to a mowing plan depending on climate, season, and current weather conditions. Your lawn’s optimal height and your preferences will influence how often you should trim it.
