Should I Mow Before Lawn Treatment? How to Prepare for a Lawn Service Visit

Written by Chase Coates | Feb 27, 2024

If you’re an over thinker, preparing for your lawn care company visit can stress you out.

Should I mow before lawn treatment? Should the grass be short for fertilizer? Long for weed control?

If I mow right before, will I ruin everything?

Relax. We have the answers. 

Should you mow before or after a lawn treatment? It depends a bit on what exactly your lawn treatment will be. 

Let’s take a look.

Fertilizer: Should I Mow Before Lawn Treatment?

Nope. 

Some of those fertilizer nutrients are absorbed through the plant tissue, so it’s best to have some surface area for the fertilizer to land on. That means longer grass is better. 

What if you mess up, forget, and mow before the lawn techs come?

Don’t panic. It’s not a huge deal. The fertilizer will be absorbed by the roots along with water, and will be eventually taken up by the grass.

Weed Killer: Should You Cut Grass Before Lawn Treatment?

Nope. 

You don’t want your lawn too short right before weed control is applied. 

The more weed, the better. That means more weed killer will actually get on the weeds and get to work killing the scoundrels.

Then, avoid mowing for at least 24 hours — 48 hours is even better.

You want to leave plenty of time for the weeds to absorb that herbicide.

Insecticide: Should I Mow Before Lawn Treatment?

It depends. 

If you’re getting a contact insecticide that kills bugs when it hits them, you want the lawn to be a bit shorter so that the product can easily get down to where the bugs are. You don’t want a bunch of tall grass blades getting in the way. 

If you’re getting a systemic insecticide that kills bugs when they eat the grass, it doesn’t matter as much if the grass is shorter.

That kind of insecticide is absorbed and moved throughout the grass. If you want to get all science-y for a minute, that process is called translocation. Pull that fact out at your next barbecue and impress the heck out of your friends.

How do you know which kind of insect control you need? It’s tricky. 

Lawn care pros can help you figure out what bug or bugs are damaging your lawn, and will suggest an insecticide or other treatment to get rid of them.

Mow Before or After Lawn Treatment? Why After Matters

It’s actually more important  to avoid mowing too soon after a lawn treatment, so you don’t mow off whatever good stuff is on your grass before it has a chance to work.

Speaking of Mowing…

When you do mow, do it right. Not too short, please. 

Cutting your grass too short stresses the grass, and makes it more susceptible to damage from insects and disease. Never cut off more than a third of the grass blade at any one time.

That way, the grass will develop a deeper root system to support the longer blades and need less water. That leads to a fuller, greener lawn.

What Else Should You Do to Prepare for a Lawn Treatment?

  • Turn off your irrigation system the night before a lawn treatment so your lawn isn’t wet when your lawn care company technicians arrive. If the grass blades are too wet, products won’t stick.
  • If your lawn is too wet or if your irrigation system is running, they’ll have to skip your property and return later.
  • Clear your lawn of any items, including toys and pet items.
  • Make sure your pets’ food or water bowls are away from areas to be treated. If you forget, discard any food or water and clean out the bowls after the treatment.
