Should I Mow Before or After a Lawn Treatment?

Many people ask how long to wait to mow after lawn treatment, or if they should mow before a lawn treatment. The rule is actually pretty easy to remember: Don’t mow 24 hours before a lawn treatment or for 24 hours after.


You want as much surface area of the weeds’ leaves available to "catch" the weed killer. Mowing before a lawn care treatment will cut off those leaves.

After spraying, you want to give the plant time to absorb the weed killer and move it throughout the plant. If you mow it right off, it doesn't have time to make its way through the weeds.

What about fertilizing? Can you mow and fertilize on the same day? Nope. Same rule applies.

As long as we’re talking about mowing rules, there are some other important lawn mowing tips.

Mowing is about more than making your grass shorter. The way you mow has a big impact on the health and thickness of your lawn.

Prep Your Mower for the Busy Season Ahead

Before you launch into the Midwest lawn mowing season in May, make sure your mower blade is sharp, the tires are aired up, and the oil is changed. Do this every month for the best mowing results.

A dull mower blade “rips” the top off a blade of grass, leaving a jagged edge that invites pests and disease.

A sharp blade makes a nice, clean cut, which helps the grass to heal faster and helps it grow thicker.

How Tall Should You Mow Your Grass?

If you’ve hung out here with us at all, you know about mowing tall. 

Mow your lawn to remove a third of the current grass height. Grass should be 3 to 4 inches tall after mowing.

As summer progresses, you should keep raising your mower blade. Shoot for 3 inches in June, 3.5 to 4 inches in July and August.

If you mow too short, it actually hurts your grass. When you mow, you’re removing a portion of the leaf surface that creates food through photosynthesis.

Take off too much, and you’re starving your grass.

Taller grass helps a lawn grow thicker and stay greener. Mow too short, and the soil heats up, helping pesky weed seeds to germinate. 

Resist the urge to mow extra short for the winter. There’s no reason. Mowing shorter than 2.5 inches will just stress your lawn. 

Should You Bag Your Grass Clippings?

Another lawn mowing tip to remember, you don't nee to bag your clippings. Maybe you’re the tidy type, gathering up all your grass clippings in bags and whisking them away. 

Meanwhile, your grass is shouting, “Noooooooooo!” 

Skip the bags. Those grass clippings can head right back to the soil as mulch. 

The bits of grass fall down to the soil level where they’ll begin decomposing, acting as a natural fertilizer your lawn will love. 

Hot? Rainy? When to Mow?

Avoid mowing when it’s really hot. It stresses the grass.

Also, avoid mowing when your grass is still wet with dew. Mowing wet grass makes it more susceptible to disease

Also, wet grass is slippery. You don’t want to end up with a cast. 

Change Your Mowing Patterns

Over time, grass leans in the direction you mow. If you change direction every time, it will help the grass grow straight up versus leaning in one direction.
