When Should I Mow The Lawn?
Every grass has an ideal mowing height. It doesn't matter whether you're tending cool-season grass in Minnesota or warm-season turf in Houston Texas, your particular type of grass has specific height requirements. Maintain your lawn at the ideal height, and you'll be rewarded with lush, healthy turf that easily fends off weeds, drought and disease.
Forget the lawn-mowing myth that says the shorter you mow grass, the less often you'll have to cut it. That misguided concept lays a foundation for a problem-prone lawn. Grass that's cut too short is more susceptible to weed invasion, drought and heat damage.
Let your grass grow too long between cuttings, and you run the risk of creating an ideal habitat for insects like mosquitoes and critters like voles, mice and snakes. Grass that's too long is also hard to mow, and the extra-long clippings create more work, since they usually need to be raked or bagged.
It's worth the extra effort to mow a lawn frequently enough to maintain the ideal height. Even during peak growth, you'll probably only be mowing every five to seven days-at most. Your mowing frequency ultimately depends on your lawn's ideal height, which varies during the growing season and depends on growing conditions.
Cool-season turf, which includes fescues and Kentucky bluegrass, grows the most during the cool temperatures of spring and fall. While specific heights vary, the typical range for cool-season grasses falls between 1 and 4 inches high.
Warm-season turf includes St. Augustine, Bermuda, centipede and zoysia. These grasses achieve their peak growth when summer hits its stride. Specific mowing heights vary by grass type and can even be different for different types of the same grass. For instance, mowing height for Empire zoysia is 0.75 to 3 inches, while Zenith zoysia thrives when cut to 1.5 inches, and even those ideal heights vary by region.
The general rule of thumb for mowing is never to remove more than one-third of total grass blade length at a single cutting. The easiest way to accomplish this is to discover what your turf's ideal height should be and allow it to grow one third longer before mowing.
Follow these general guidelines to cut your grass at an ideal mowing height.
