Aeration and Overseeding | How to Protect Your Lawn
Over-aerating your lawn can cause damage to the grass and soil.
The best time to aerate your lawn depends on the type of grass and your climate.
Most lawns benefit from annual or bi-annual aeration.
Common mistakes to avoid when aerating and overseeding include aerating too deeply or too frequently, overseeding at the wrong time, using low-quality seed, and failing to properly prepare the soil.

Can You Over Aerate?

Yes, you can over-aerate your lawn. Over aeration is when you aerate too much and cause damage to your lawn by removing too much of the thatch layer. The amount of thatch an average yard should have is approximately 3/4” (1-1/2 cm) deep or less. If you remove more than this from your lawn, it will end up being overdone and damaged because of the excess wear on its root system.

What Happens If You Over Aerate?

Over-aerating is a problem if you remove too much of your lawn’s soil. The soil contains many microbes that help break down organic matter and nutrients in your grass. 

If you remove too much of this soil, the microbes will be killed and your lawn may become more susceptible to weeds or poor grass growth.

How Do You Know When Your Lawn Has Been Over Aerated?

You can tell if you have over-aerated your lawn by looking for brown spots on the grass. You should also look at whether the brown areas are soft or hard when you walk on them with your hands. If it’s soft and spongy, then it means that your lawn has been over-aerated.

It’s important to know how much air is being injected into the soil before deciding whether or not to continue with this process. 

Once the air reaches a certain level, then it will start pushing out all of the oxygen from within the soil, causing death in plant roots and bacteria living below ground level too – which could lead to unhealthy conditions for other plants!

Is It A Good Idea To Over Aerate?

On the other hand, over aeration can have some damaging effects on your lawn. In fact, if you over-aerate too often and too much at once, it’s possible that your lawn will die off! Over-aeration causes soil compaction and plugs up the pores in the soil, preventing water from being absorbed into the ground. 

This can result in drought conditions which will lead to brown patches on your lawn. Additionally, when you puncture holes through the surface of your soil during over-aeration (and even when you don’t), pests like moles or voles are able to sneak into those holes and access your roots for food or shelter.

Finally, if you’re not careful about how much oxygen gets into those pores with each pass of an aerator machine (which we’ll talk about later), then there’s a chance that harmful microbes could enter as well!

Are you tired of paying for expensive lawn care equipment? Consider using a garden fork to aerate your lawn instead. Our article on aerating your lawn with a garden fork offers tips and advice to help you achieve a healthy lawn without breaking the bank.

What Are The Benefits Of Over Aerating?

Over-aeration has many benefits for your lawn:

  • It improves drainage, which will make it easier for your lawn to get rid of excess water and prevent flooding.
  • It increases the oxygen content in soil, which helps plants grow better and become more resistant to disease.
  • It allows grass roots to grow deeper into the ground so that they can take advantage of nutrients that are farther down. This makes them stronger and healthier overall.
  • It helps thicker roots form near the surface, so even if you don’t have a lot of time or money to spend on watering or fertilizing your grass, it will still look great!

6. What Are The Risks Of Over Aerating?

While there’s no question that aerating your lawn will have positive effects on its health, there are also risks involved. 

One of the most significant is that you can damage the root system of your lawn and make it more susceptible to disease and weeds. 

This can happen when you go too deep with the spikes, which cut into the roots as they go through them. If done incorrectly or repeatedly over time, this can cause serious damage and weaken your grass up to 80%.

Are There Any Ways To Avoid Over-Aerating Your Lawn?

The best way to avoid over-aeration is to make sure you use the right size aerator for your lawn. If you have a large yard with thick grass, it’s probably not necessary to have an aerator that can penetrate deep into the ground. 

Instead, you’ll want to find something that’s designed for ordinary soil conditions, like most homeowners’ yards. This will help prevent excessive compaction and damage from occurring during your next session of lawn care.

Another way to avoid over-aerating your lawn is by using too much weight on the machine while pulling it along behind you. 

While this may seem like a simple solution at first glance (i.e., more weight = deeper penetration), this method actually has some drawbacks when compared with other methods such as increasing the size of your tines or going faster while mowing without having any additional weights attached directly onto them instead (or both). 

For example: if someone were using only one pound per square inch as their standard measurement then they would need four times more pressure than someone who used three pounds per square inch — all else being equal!

Fertilizer is essential for maintaining a healthy lawn, but it can also be a double-edged sword. Check out our guide on how to avoid burning your lawn with fertilizer to learn how to apply it safely and effectively

What Is The Best Way To Avoid Over-Aeration?

There are several different ways that you can aerate your lawn. If you want to avoid over-aerating, here are some suggestions:

Use a core aerator – A core aerator uses tines at the bottom of its blades to penetrate deep into the soil. It will take out cores from below, so it’s only effective for grassy areas that aren’t too thick and don’t have any hardpan underneath them (such as clay). 

This type of machine may be better suited for homeowners who don’t hire someone else to do their yard work every week; otherwise, it might be difficult for them to operate such heavy machinery on their own without causing damage elsewhere on their property.

Use a spike aerator – Spike aerators are similar in nature as core aerators except they’re not as deep (and therefore less likely) when used by amateurs or homeowners who aren’t familiar with these kinds of machines yet still want something more powerful than just handheld forks or spoons! 

They also tend not ike due because they’re easier than using traditional digging tools like screwdrivers or shovels which require more physical strength than most people possess especially if they’ve never done landscaping before themselves!

When Does It Make Sense To Aerate Your Lawn?

When you are seeding your lawn. Aeration is a great idea before you seed your lawn, because it allows more oxygen and water to reach the roots of emerging grass plants. This helps them grow better and faster, which means they will get established in their new location.

When you are reseeding your lawn. If you have a bare spot in your yard that needs to be filled in, aerating the area before reseeding will help get the seeds started at an earlier stage so that they can take root quickly once they’ve been planted into moist soil.

When you are overseeding your lawn. Overseeding is when you apply new grass seed over existing turf to repair damaged areas or add color variety to an established turf area such as a sports field or backyard lawns by adding various species of perennial ryegrass at different times during the year depending on where it grew best during its first season (some varieties do better under shade).

 Using this method helps prevent weeds from taking over even though there will still be some weed growth due to being exposed sunlight all day long without being shaded by any trees nearby; however overall maintenance costs per square foot should still drop significantly because fewer chemicals needed applied less frequently than normal mowing schedules 

Would require without aerating beforehand since most weeds cannot survive without light from above shining upon them directly overhead 24 hours per day 365 days out

How Often Should You Aerate Your Lawn?

It depends on the type of grass you have and how sandy or clayey your soil is. If your lawn is on clay, it should be aerated more often than if it’s on sand.

 Most experts recommend that you aerate once a year, but if you have a lot of foot traffic or play sports on your lawn, then twice yearly may be necessary. 

The best time to aerate is in the fall when temperatures start to cool down so that there are no problems with disease or insect damage being caused by higher temperatures during summer months.

Aeration Is Great, But Don’t Do It Too Much!

While aeration is great for improving soil health, be sure not to overdo it. This can lead to some major problems with your lawn and even harm your grass overall. You don’t want that! So here’s the scoop:

Aerating helps improve the health of your lawn by allowing air and nutrients in, but it can also make it easier for weeds and pests to take hold if you overdo things (and who wants pesky bugs?).

You don’t want to aerate too often because that can cause damage as well something we’ll talk more about in a minute. Just like you wouldn’t want to water too much or fertilize too much either!

There are several signs that indicate when you might have over-aerated your yard: holes left behind from plugs sticking out, large clumps of plugs scattered about after pulling them up, brown patches on the lawn following aeration.

If any of these happen then chances are good that something went wrong during this process–so check yourself before wrecking yourself!

If you’re planning to reseed your lawn, it’s important to know whether your lawn seed is still viable. Our article on whether lawn seed can go bad provides the answers you need to ensure successful lawn growth.


The answer to the question “Can you over aerate?” is yes. It’s possible to over-aerate your lawn. However, it’s also important to understand why this can happen and what can be done about it.
