What Happens If You Mow Your Grass Too Often? (Solved!)

Cutting your grass can sometimes feel like a huge chore, but the look of a perfectly mowed lawn is super satisfying. You might find yourself mowing your lawn all the time in summer in order to keep your grass neat for any outside occasion.

However, it is possible to mow your grass too often, and your insistence on keeping the lawn perfect at all times could actually be doing your grass more harm than good. 

If you mow your grass too often, your lawn will begin to look too bald, and the grass will become depleted in nutrients if it is not given the chance to grow. You might end up putting too much tension on the grass plants and pull up your turf. 

It can also cause the build of thatch (the spongy top layer of soil), which can compromise the lawn’s health by preventing sunlight, water, and nutrients from getting to the roots of your grass.

Dangers of Mowing Your Grass Too Much

If you cut your grass too often or cut too much grass in one go, you can damage the health of your lawn. 

You may have heard of thatch, as it is a pretty common problem with lawns. Mowing too often is one of the causes of thatch build-up. 

Thatch collects on the soil’s surface and becomes intertwined with the grass, which makes it really difficult for the healthy grass to grow. As it thickens, it can essentially choke your lawn, as it prevents your soil from getting a sufficient amount of air, as well as hindering water absorption and stops nutrients from getting into the soil and roots.

To keep your grass healthy and make sure your lawn can be cut as often as you like, Flymo advises dethatching your lawn at least once a year.

So, how much grass should be cutting to prevent thatch from building up? As a rule, gardeners advise only cutting a third of the height of your grass in one go. This way, you are not damaging the roots or pulling on the grass plants, but strengthening the individual blades.

How Often is Too Often To Mow Your Grass?

For most lawns, mowing about once a week is appropriate. If you are cutting more frequently than this, your lawn might begin to look scalped, as the grass has not had enough time to thrive.

However, how often you should be mowing your grass depends on the climate you’re in and the season. It is unlikely that your grass is growing at the same rate all year, so it would not make sense to consistently mow it at the same intervals either.

In the summer, you might need to mow your lawn every five days, as the grass grows significantly faster. However, it is also worth noting that you will want to keep your grass a little longer in the warmer months. This is because it will protect the soil from the sun and evaporation, plus having healthier soil will help your grass in the long run.

In the winter, you will most likely find that your lawn growth really slows, so cutting your grass once a month might be sufficient. 

Either way, it is essential to remember to only cut one-third of the height of the grass. If you do this too often, your grass is going to get too short to look neat.

In the spring and fall seasons, cutting your grass about once a week should be the perfect amount. This should stimulate its growth and help it to survive colder weather without it getting matted and untidy.

How Often Should You Mow New Turf?

Extra precautions should be taken when mowing new turf, as it is even easier to mow a new lawn too often. The ground will most likely be much softer than a lawn that has been down for a long while, therefore it is more vulnerable to a lawn mower’s blades.

New turf should only be mowed after 3 weeks to a month of being out down. If you cut the grass too soon, you could slow its growth or even rip the turf up, creating a muddy mess.

To see if your turf is ready to be mowed, you can choose a patch of grass to test first. Grab a handful of the grass and tug. If the blades of grass easily break off in your hand, your new turf is ready for a cut.

If there is not enough turf to grab, it is too soon to mow your lawn. Likewise, if you pull up the plants and expose soil when you tug the grass, it is too soon to mow as a lawnmower will lift the turf and ruin all of your hard work.

Once you have mowed your new turf, you can follow the normal mowing rules and aim to mow your lawn once a week. This will strengthen the grass and prevent it from getting messy and overgrown.

However, if at any point the lawnmower seems to be damaging your new turf, be sure to give your lawn a break. It can sometimes take a little while for new turf to settle, and mowing your lawn too often could disrupt this settling process.

Using The Right Lawnmower

Lawnmowers can last a really long time, and you’ve likely had the same one for years. This probably means that you haven’t really thought about its condition and how it is cutting your grass.

Check out some of the best-rated lawnmowers to see how yours measures up. It could be that you’re mowing too often (and therefore ruining your lawn) because your lawnmower simply isn’t up to the job anymore.

To achieve a better cut, it might be time to say goodbye to your trusty old lawnmower and welcome a new one to the garden, as it will guarantee a sharper, more even cut that will keep your grass in excellent condition without it requiring a cut too often.
