6 Benefits of Aeration and Overseeding for Your Indiana Lawn

There are a lot of great things that you can do to promote a healthy lawn at your Indiana home. But if you aren’t also investing in aeration services, you’re not going to see the best results.

In this article, we’ll talk about the benefits of aerating your lawn.

We’ll also answer the question: Can aeration and overseeding really improve a struggling lawn?

Spoiler alert….the answer is overwhelmingly yes. Aeration and overseeding can have a big impact on improving a struggling lawn.

We totally understand that homeowners are reluctant to spend money on services if they don’t understand the benefits or feel they really need them. Sometimes lawn aeration gets looked at as an “extra” and that makes people classify it as something they don’t actually need to invest in. But aerating your lawn can be the difference between a lawn that looks OK and one that looks amazing.

Let’s talk about why!

What Does Aerating a Lawn Do?

Why aerate a lawn in the first place? What’s the reason behind this service? The simple answer that you’ll often hear is that aeration helps a lawn to breathe. But it’s a little more complex than that.

First, it’s important to understand there are actually two types of aeration: Liquid aeration and mechanical core aeration.

Both forms of aeration aim to improve the health of the soil by relieving compaction. Here in Indiana, our soils are primarily composed of clay, which is particularly prone to becoming compacted. Everyday use of the lawn can squeeze the already-tight pore space together. That makes it hard for your lawn to take in oxygen, nutrients, and water.

But aeration services can counteract that.

We offer both liquid and core aeration and we recommend that homeowners invest in both if they’re truly looking for the best results.

What does core aeration do?

With mechanical core aeration a machine called an aerator is used to extract plugs of soil (we call them “soil cores”) from the ground.

People think this service is all about creating those holes to allow the lawn to breathe, but it’s also all about the cores! The soil plugs are intentionally left lying on the ground where they'll naturally break down and settle back into the earth over time. This leaves behind, looser and healthier soil with improved microbial activity.

What does liquid aeration do?

At Shades of Green, we call our liquid aeration service “Soil Builder,” because that’s exactly what this service does.

We mix up a proprietary cocktail designed to rehab tired, compacted, sad-soil lawns and turn them into thriving green machines. This blend immediately gets to work boosting microbial activity, which helps break down thatch layers and old clippings over time, warms up the soil, and even releases nitrogen naturally as things decompose. That means greener grass, stronger roots, and less buildup of that annoying layer that makes your lawn feel like a sponge.

In this article, we’re going to focus more on mechanical core aeration (the “OG” aeration service) but it’s important to keep in mind that using both of these aeration services in Indiana can yield superior results. It’s not an “either/or” situation.

What Are the Benefits of Core Aeration?

The benefits of core aeration are numerous! Lawn aeration can truly make a huge difference in your lawn’s overall health, particularly if your soil is compacted (which, here in Indiana, most lawns are).

Here’s what you can anticipate:

1. Improved oxygen flow: More air is able to reach the root zone, which will support healthy root growth.

2. Enhanced water infiltration: By relieving compaction, water can penetrate the soil instead of running off or pooling at the surface. This will help it reach the root zone, where it’s needed.

3. Better nutrient uptake: Fertilizer and other nutrients can better reach the root zone in soil that is aerated.

4. Reduced thatch: That spongy layer of thatch can become a problem if given the opportunity to grow thick. But core aeration can help break it down.

5. Improves the effectiveness of overseeding: When aeration and overseeding are performed at the same time, the loosened soil provides better seed-to-soil contact for the seeds, improving the chance of germination.

6. Promotes thicker, healthier turf: Improved growing conditions will ultimately produce thicker, healthier grass. Healthier turf is going to be able to better stand up to problems.

How to Tell if Your Lawn Needs Aeration

A lot of people describe their lawn as looking “tired” or “struggling” when being in need of aeration. But there are some signs that you can watch for.

• Water is pooling or running off: When water isn’t soaking into the lawn, it can be a strong clue that the soil is compacted and lawn aeration is necessary.

• Grass is thin and struggling: If you’re fertilizing your lawn and caring for it properly but it still doesn’t look its best, lawn aeration could be the difference maker.

• You have bare patches: Over time, those thin areas can become full-blown bare patches. This is also a good reason for overseeding after aeration.

• The soil feels hard: You can definitely tell when the lawn feels hard and compacted. You might also try a simple soil test, such as trying to push a screwdriver into the soil. If that’s hard to do, the soil is compacted.

What Are the Benefits of Overseeding After Aeration?

Overseeding the lawn immediately following a core aeration service is valuable because it provides the optimal seed-to-soil contact that is needed for that grass to germinate. When seeding right after aeration, the soil is looser and even has holes that the seeds will fall into. This is going to create the best growing conditions for the seed and give it the best start to life.

When you overseed without aerating, you run the risk of wasting a lot of that seed. It ends up just sitting on top of the hard soil and might even dry out or become expensive bird seed before ever getting a chance to grow.

You might be wondering: Do you really need to overseed after aeration? We definitely recommend it for a few reasons.

Some of the benefits of overseeding a lawn include:

• Filling in thin areas and bare spots: A primary reason why people overseed their lawns is to fill in bare spots and thin areas with new growth. This thickens the lawn and creates a denser turf.

• Introduces new grass plants: We’re also using overseeding to introduce new and more resilient grass types into the lawn. This can improve overall health as some of the newer varieties are more resistant to disease and drought stress.

• Creating density: As new grass fills in, the lawn will become thicker which improves the overall lawn appearance. This increased thickness will also help crowd out weeds.

• Extends the life of the lawn: Overseeding also plays an important role in rejuvenating turf and making the whole lawn look refreshed.

When Should You Aerate and Overseed Your Lawn in Indiana?

Because of how common it is for lawns to become compacted, we actually like to aerate twice a year, in the spring and the fall. If you’re someone who is looking for the best-possible results and want to do everything you can for your lawn, then we’d recommend bi-annual lawn aeration services.

However, here’s an important caveat: Overseeding is best done in the fall.

This is a time when the weather is optimal for new germination. The air is starting to cool down but the ground is still warm. We do not recommend overseeding in the spring as seed will be susceptible to pre-emergent weed control and can dry out too quickly as the sun heats the season up.

FAQs About Aeration and Overseeding Benefits

What to expect after aeration and overseeding?

Immediately following a core aeration service, your lawn might look a little rough. That’s completely normal. Those soil plugs will be visible on the surface and should be left alone to naturally decompose. Make sure that you are keeping the seed moist in the first few weeks by following watering recommendations.

Can aeration and overseeding fix every thin or bare area in your lawn?

It can take time to fix a lawn that is in really bad shape. If you have more thin and bare spots than you do healthy turf, it could take more than one season of aeration to begin to restore things. But if you trust the process, you will start to see results.

How long does it take to see results after overseeding?

You’ll see some new germination start to sprout as soon as a week but it’ll be some time until it actually fills in and looks like a lawn. It’s imperative to follow watering instructions after a lawn aeration service.

How often should you aerate and overseed a lawn in Indiana?

If you truly care about getting the best results, we recommend aerating and overseeding at least once a year. But you’re going to get the best results if you aerate every fall and spring.

How much should you water after aerating and overseeding your lawn?

It is important to follow the recommendations of your lawn care provider when it comes to watering the lawn after aeration and overseeding.

In the first week, aim to water lightly but frequently. The soil should be damp, but not flooded, so as not to wash away the seeds. After the first week, you can start to taper off to longer, deeper watering sessions. This helps to encourage roots to grow downward and establish themselves.

Can you walk on your lawn after aeration and overseeding?

You should try to stay off the lawn as much as possible immediately following an aeration and overseeding service. You want to make sure that you don’t impede the seed-to-soil contact that is happening. After seedlings emerge, light walking is okay, but you should still avoid heavy use. Wait until new grass is more established to resume normal use.
