A lot of homeowners think that cutting their lawn super short will give it a neat, putting-green-like look. However, they soon discover that this neat look is short-lived as they start to see things like brown patches, thin spots, or even yard pests.

When you mow your lawn too short, it leaves your soil and turf too exposed to weather, pests, potential diseases, or weed infestations. At the same time, letting it grow too long can prevent it from getting the sun, water, or nutrients that it needs.

We believe that there is an art and a science to mowing to the perfect height. There is a lot of misinformation out there about this topic, so let’s set the record straight and talk about why it’s about more than just aesthetics.

How to Mow a Lawn to the Perfect Height

As a good rule of thumb, you will want to trim your grass to about 4” (or 10 cm) to ensure it has enough length to protect your soil, and you never want to remove more than one third of the blade when you mow.

You may also want to leave a little more length during peak summer months for added protection from the sun and heat.

However, these are just guidelines. Your best bet is to contact a local lawn care expert who has firsthand experience with your specific grass type and knows the local weather.

Pro Tip: Always Sharpen Lawn Mower Blades

A dull lawnmower blade can tear the grass instead of cutting it clean. This can slow the healing process and leave you open to a possible turf disease attack.

You’re going to want to have your blade sharpened as soon as you buy a new lawnmower. It may surprise you to learn that factory blades on new mowers aren’t sharp.

From there, you will want to sharpen it once or twice a year, depending on how often you’re mowing.

Of course, you can find YouTube videos that show you how to remove a lawn mower blade, as well as how to sharpen a lawn mower blade. But there are also local small businesses and hardware stores that can take care of this for you.

How Often Should I Mow My Lawn?

This depends on how much rain and sunshine your area is getting, which will dictate how quickly your lawn grows.

• Peak periods may need you to mow more than once a week

• Slow periods may stretch that to once every two weeks. Maybe more

The Rule of Thumb That Most People Don’t Know

Never cut more than 1/3 of the leaf blade in a single cutting.

Removing too much will stress the grass and can cause it to turn brown. This means that if your lawn has grown excessively long, you should raise your mower to the highest setting before mowing.

Should I Bag My Clippings?

Bagging your clippings is not only a pain, but it could also actually hurt your lawn.

Returning your clippings to your lawn (or grasscycling, as it is known) is good for the environment and good for your lawn.

Letting the clippings decompose on your lawn gives valuable nutrients back into the soil. The only time you should remove clippings from your lawn is if they are excessively long and will smother the grass.
