You water, you mow, you fertilize—you do all the right things for your lawn. So why does it still look a little thin and tired? You might have noticed that it feels a bit spongy when you walk on it, or that water just doesn’t seem to soak in the way it used to. These aren’t just random lawn issues; they’re often signs of a silent problem hiding right under your feet: a thick layer of thatch.
At LNG-Hartigan, we’ve seen countless lawns in the Metro Minneapolis area that are struggling for this exact reason. Many homeowners don’t even know what thatch is, let alone that they have a problem. Simply put, thatch is a layer of living and dead organic matter, like old grass clippings, roots, and stems, that builds up between the green blades of your grass and the soil below. While a tiny amount is healthy, a thick layer can suffocate your lawn. Dethatching is the key to getting your lawn to breathe, absorb, and grow to its full potential.
What Is Thatch and Why Is It a Problem?
Imagine trying to breathe through a thick, wet blanket. That’s what your lawn’s roots are doing when there’s too much thatch. This dense layer prevents air, water, and nutrients from reaching the soil. When this happens, your grass’s roots start to grow in the thatch layer itself instead of digging deep into the soil. This makes them weak and vulnerable to drought, heat, and disease. So, before you grab more fertilizer or water, the first step to fixing a tired-looking lawn is to figure out if you need to tackle a thatch problem.
5 Telltale Signs Your Lawn Needs Dethatching
How do you know if it’s time to take action? Your lawn will give you plenty of clues. You just have to know what to look for. Here are five of the most common signs we see that tell us a lawn is in need of some professional dethatching.
1. The Spongy Step
Go outside and take a walk on your lawn. Does it feel particularly soft or spongy under your feet, almost like a springy mattress? That bounce is a direct result of a thick layer of thatch that’s built up over time. It may feel a little nice, but it’s a clear indication that your lawn’s root system is not properly connected to the soil below.
2. Water That Won’t Soak In
Have you ever watered your lawn only to see the water puddle and then run off into the street or driveway? Or maybe you notice that your lawn seems to dry out incredibly fast after a good rain? A thick layer of thatch acts like a waterproof sponge, holding water on the surface and preventing it from penetrating down to the root zone. Your grass can’t thrive when its roots are thirsty.
3. Fading Color and Weak Growth
A lawn struggling with too much thatch often looks weak and pale. Because the grass can’t get the water and nutrients it needs, it might lose its vibrant green color and look patchy or yellow. If you’ve tried fertilizing but aren’t seeing the results you expect, it’s a good sign that the nutrients are stuck in the thatch layer and can’t reach the soil. The grass is essentially starving.
4. The Rise of Pests and Diseases
A heavy layer of thatch creates the perfect damp, cozy home for pests and lawn diseases. Fungi love to grow in the moist, warm environment that thatch provides, and it’s a great hiding place for insects. By removing this layer, you’re not just improving your lawn’s health; you’re also taking away the welcome mat for unwelcome guests.
5. The Thatch Check
The most reliable way to check for a thatch problem is to simply look for it. Grab a small garden trowel and dig up a little wedge of your lawn. We’re talking just a small section, about 2-3 inches deep. Now, take a look at the layers. You should see the green grass blades on top and the soil at the bottom. In between, you’ll see a brownish, matted layer. If that layer is thicker than about half an inch, your lawn has a thatch problem that needs to be addressed.
The Benefits of a Professional Dethatching Service
Once you’ve identified that your lawn has a thatch issue, you have a couple of options. You could try to do it yourself with a manual rake, which is a lot of work and often not very effective on larger lawns. Or, you can bring in the professionals. At LNG-Hartigan, we use specialized equipment to get the job done right. A power rake is designed to efficiently and gently pull up that dense layer of thatch without damaging the healthy grass.
Here’s what our professional dethatching service does for your lawn:
- Allows Your Lawn to Breathe: We remove that suffocating layer, allowing air, water, and nutrients to finally reach the soil.
- Encourages Deeper Roots: When the roots can grow deep into the soil again, your lawn becomes stronger and much more resilient to drought and heat.
- Boosts Fertilization & Overseeding: After we’ve dethatched your lawn, it’s perfectly prepared to make the most of fertilizer applications and for new seeds to take root if you choose to overseed.
