If there’s one thing that St. Augustine grass—the most common type in our area—doesn’t like, it’s improper lawn mowing. It’s tempting to cut the lawn as short as possible in order to go longer between mowing sessions, but it’s risking the health of your lawn. Mowing at the right height is an important part of maintaining a lush, beautiful lawn.
Why mowing matters.
The grass needs sunlight, but cutting it too short allows too much sunlight to reach the soil in which it grows, and that’s where the problems begin. Not only will the soil dry out more quickly, which stresses your grass and allows pests to attack, but weed seeds will have the light they need in order to germinate.
At the other extreme, allowing your lawn to get too tall between mowings can make your grass a better home for all types of pests, including insects.
So what’s the proper mowing height for a warm-season turf grass such as St. Augustine? Most experts recommend a height of 3.5 to 4 inches during the active growing season. In general, the rule of thumb is to never cut off more than a third of the total height of the grass blade in one mowing session. You may need to mow about every five days during the warmest months, and perhaps twice a month when growth slows down in late fall and winter.
Although it’s a bit of a hassle, if you have some grass that grows in shady areas, it should be cut even higher than areas that get a lot of sunlight. Grass in shade may have to compete for nutrients with the roots of trees; the more leaf blade that’s left, the better the grass can compensate for the reduction in light.
