A Simple Guide To Dethatching Your Lawn
Dethatching is a strange word; one that I had never heard before taking my lawn care more seriously. But as it turns out, it’s one of the most important tasks on your lawn care schedule. Here’s everything you need to know to start detaching your lawn like a pro.
So, let’s get down to the grass tacks…
What is Dethatching?
A Simple Guide To Dethatching Your Lawn
Dethatching is the process of removing the layer of dead grass, roots, and other debris that accumulates on your lawn over time. This layer is called thatch.
Think of dethatching like raking except, instead of raking debris off of the surface of your lawn, dethatching goes deeper to rake the debris off the surface of the soil.
Reasons For Dethatching Your Lawn

Earlier I said that dethatching is one of the most important steps in a lawn care plan. There are a few good reasons for that:
Thatch buildup creates a barrier above the soil; effectively suffocating your lawn. This can prevent water, air, and nutrients from reaching the soil and roots of your grass, causing your lawn to become unhealthy and patchy.
Thatch can also create a perfect environment for pests and disease, which can harm your lawn even further.
Removing thatch can help your lawn develop a deeper root system, which in turn will make it more resilient to drought and other environmental stresses.
Now, let’s move on to how to dethatch your lawn.
Dethatching Tools Based on Lawn Size

There are several tools that work great for dethatching based on the size of your lawn, including:
Small Lawns: I suggest using a standard metal bow rake like this. This method requires a little more physical labor but is extremely effective.
I like to rake hard on an area of thatch while moving around the area in a circle (continuously raking). This ensures the thatch is pulled up from all angles and the soil is nice and stirred up for when it’s time to put new seed down.Small Lawns: If you don’t mind having additional tools in the garden shed, you might want to spring for a specific dethatching rake (like this) to manually remove the thatch layer. This is a good option for smaller lawns or isolated problem areas.
Mid-sized Lawn: a power dethatcher (like this) is a simple option to quickly remove thatch from larger lawns.
Large Lawns: If your lawn is over one acre, you should probably consider a pull-behind dethatching accessory like this.

Once you have the right dethatching tool for your lawn size, it’s time to get to work. While the type of tool you are working with will ultimately determine the exact method of work, all dethatchers have the same goal to keep in mind.
Remove the dead grass: Look for brown spots in your lawn and ensure that you are removing all of the dead grass. This means raking the spot pretty hard. It might leave you with bald patches of soil. Having soil patches is much better than dead grass patches. Now, when you over seed, the chances of healthy grass growing are much better.
Remove Moss: If you have moss patches, rake them out completely to leave bare soil behind. These soil areas will need reseeded.
Remove other debris: rake out all rocks, sticks, kids toys, animal hides, etc. Get rid of anything that is sitting on top of the soil preventing sun light and water from getting in or preventing grass to sprout up.
Don’t get worried if your lawn looks worse after dethatching. It can be a little scary to see what looked like a thick, albeit brown lawn suddenly turned scraggly and bald. This is normal. Now you have the opportunity to reseed the bald spots and overseed the entire lawn. Within a couple of weeks you’ll see a world of improvement.
How Often Should You Dethatch a Lawn

The answer is, it depends…Different lawns require different approaches. You need to figure out the type of grass in your lawn, run a soil pH test, and walk around the lawn to get a good visual idea of thatch accumulation.
But generally, it’s recommended to dethatch your lawn once every 2-3 years if you have cool-season grass and once a year if you have warm-season grass.
If you‘re not sure if your lawn needs it, just do a light dethatching. No need to go crazy. Just a gentle once over with your dethatching tool to make sure the soil is free to breathe and absorb moisture.
Regularly dethatching your lawn is important for the health and beauty of your lawn.
Dethatching Vs. Aerating
A Simple Guide To Dethatching Your Lawn
There seems to be a common confusion about the difference between dethatching and aerating. To be clear, these are not the same process, nor are they interchangeable. Both processes are equally important to your lawns health and must be completed separately.
It’s actually recommended to aerate your lawn after dethatching. Aeration helps to relieve soil compaction, allowing water, air, and nutrients to reach the root system more easily.
When it comes down to it, dethatching is easy as pie and essential to the health of your lawn. The hard part is remembered to do it at the right time. That’s why we made our lawn care reminder tool. Download our reminder tools and you’ll always know when it’s time to dethatch your lawn.
