Have you ever seen someone putting tiny holes in their lawn? Wondered why they were doing that? If so, and you didn’t know what they were doing, then you need to keep reading! We will define what lawn aeration is and explain all the benefits of aerating your lawn.

What is lawn aeration?

The process of puncturing your lawn’s soil with small holes is called aerating. Lawn aeration opens a pathway to the roots in order to provide air and nutrients to keep your grass healthy. Aerating along with dethatching and top seeding results in a green and healthy lawn.

Check out the five benefits of aerating your lawn we’ve identified below.

Alleviates soil compaction

Let’s face it. People walk on our lawns on a regular basis. And, if you have kids and/or pets, our lawns are constantly being trampled. All of this foot traffic causes soil compaction, which is not good for your lawn. Why? Compacted soil inhibits air, water, and fertilizer from reaching the root system. This leads to dead spots in your yard. But when you remove small plugs of thatch and soil from the lawn during aeration, soil density decreases, which alleviates compaction.

Relieves thatch build-up

Thatch is the layer of dead grass that adds up in your yard when you mow and let the clippings land back onto the lawn. Doing this once in a while is good for your lawn since the clippings decompose, releasing water and nutrients back into your lawn’s soil. This helps grass grow greener, healthier and thicker.

However, if the thatch is too thick (i.e. it exceeds a half inch), it blocks out rain, air, light, and water from reaching the roots. Dethatching with aeration allows for these important nutrients to get to the roots. 

Enhances overall lawn health

When you aerate your lawn, you improve the overall health of the grass. The aeration process allows the root system better access to air, water, and fertilizer. Because the roots are able to receive ample amounts of nutrients, it stimulates root growth and the roots become stronger. When the roots become more extensive and deeper, the overall health of your lawn improves because the grass plants are stronger and more resilient.

Diminishes puddling

Right after you aerate, you will see that there aren’t as many puddles forming on your lawn when it rains. And then, about a week later, you’ll notice roots sprouting up in the holes. This indicates that your grass is finally receiving the oxygen, moisture and nutrients it needs to grow.

Improves air exchange between the soil and atmosphere

As we discussed previously, when the soil is too compacted, it inhibits air circulation. The aeration process unclogs the compacted soil and reduces thinning that causes your roots to suffocate.

Now, we know why it’s important to aerate your lawn. But, in order to reap these benefits, you also need to know when to aerate. 

You’ll want to aerate the lawn when grass is in its peak growing season. Why? So, it can recover quickly! Early spring or fall (or both) is your best bet in our area. So, now is the time! Get on out there and aerate!
