Following a schedule and mowing your lawn more often during the grass growing season will help you maintain a long, lush lawn. The one-third rule is the best indicator of how often you mow your lawn. It simply means that you only need to remove a third of the grass blade per cut. For example, if you cut the grass to 2 inches, wait until the grass reaches 3 inches to cut it.
Usually, mowing the lawn weekly is the rule, but some lawns need to be mowed more often. Other lawns will grow more slowly and may only need to be mowed once every ten days or two weeks. Usually, do not cut more than a third of the grass blade. More than that can damage the grass.
We spoke to Liam, with Gutter Cleaning Queens NY and he said that "Properly maintained gutters, will definitely keep your home, particularly your lawn looking beautiful and in tip-top shape all year long."
Let the length of the lawn be what you judge, NOT the last time the lawn was mowed. During the peak of growth, mowing grass can leave unsightly rows or piles of wet clippings on the surface of the grass. Mowing the lawn more often will help avoid this problem. You should trim the grass when the grass has grown 30 to 50 percent above the height at which it was previously mowed.
If the grass is kept at a height of 2 inches, mow the grass again when it reaches 3 inches. If the grass has grown to 5 inches tall, you'll need to repeat the cut a couple of times, taking only a portion of the growth in each cut. Removing too much at once will only create more clippings that can shade the remaining grass and weaken it by removing too many active leaves. Short cuttings will seep between the remaining leaves and decompose quickly.
The speed at which the lawn grows and the desired height of the lawn determine how often you must cut it. Usually, mowing the lawn once a week during the growing season should be sufficient to keep the grass healthy. The rest of the time, you can reduce the cutting frequency to every two weeks, as needed. Mowing lawns is a necessity, of course, when it comes to having a beautiful lawn.
But many homeowners wonder how often you should mow your lawn. Mow the grass too often and the grass will look bare and with a cut scalp. Cut too infrequently and the grass will look overgrown and messy. Not to mention the possibility of weeds taking hold of an oversized lawn: mowing the lawn not only keeps it looking tidy, but also keeps it healthy.
In addition, since mowing lawns cuts the top of the grass, the oldest part, it can help show the younger, fresher part of the lawn. You may have heard of the “one-third rule” when it comes to mowing lawns. This rule says that you should never remove more than a third of the blade sheet during any lawn mowing. For example, if you keep Kentucky blue grass at 3 inches, mow the grass when it grows a little more than 4 inches.
In addition, tests have shown that allowing grass to grow to a length of 2½ to 3 inches reduces the amount of weeds in the lawn by reducing the amount of sunlight that reaches weed seeds. I found it useful when you said that you should mow your lawn at least once a week to achieve a beautiful lawn. A somewhat uneven lawn may not seem like a problem, and over time, any lawn can develop uneven spots. Leave grass clippings on the grass, provided they are not damp or heavy, to fertilize the grass.
Some people like a very short lawn, such as a putting green, but doing so requires a specific variety of grass and a lot of extra care in fertilization and other types of maintenance.
