Quick Tips and Different Methods For Aerating Your Lawn The Right Way

If you’re like most homeowners, you may not realize when to aerate a lawn or How to use a Lawn aerator. You may also be wondering how much it costs to aerate your lawn, or are looking for Lawn aeration tips.

Today we’ll help you answer all those Lawn Aerator questions (and then some) in our Lawn Aeration Guide below.

Annual Lawn aeration is one of the best ways to achieve a healthy lawn. In addition, if your lawn has too many solid particles or heavy compaction at the surface, the roots will not be able to receive the nutrition they need.

These conditions will prevent the roots from growing deep healthy roots, or provide the lush thick lawn you’re hoping to achieve.

Follow these steps to learn How to Aerate a lawn, and your grassroots will grow easier and deeper into your soil.  The result you will achieve is a lawn looking that is much thicker, greener, and healthier than what was possible without lawn aeration.

What is a Lawn Aerator?

A lawn aerator is a piece of equipment that makes aerating your lawn easier and far more effective when performing your own DIY lawn aerator work.  Lawn aerators can be purchased as manual or power equipment options (see types below).

What is Lawn Aeration?

Lawn Aeration involves using a mechanical Lawn Aerator – to perforate your lawn with small holes. The perforation of your soil provides the necessary oxygen, water, and nutrients to reach the roots of your grass and move the nutrients freely throughout the soil.

What are Different Types of Lawn Aerators?

  • Pull-Behind (riding mower) – Core-plug Aerators like the Agri-Fab

  • Pull-Behind (riding mower) – Motorized Spike Aerators like the Craftsman

  • Electric Motorized “Dethatchers” such as this one from Greenworks

  • Inexpensive Manual plug aeration tools like the Yard Barber

  • Aeration Shoes – Like this model from Punchau

  • Manual rolling drums with spikes (the drum is filled with water for weight) for Yard Tuff SE

  • Liquid Aeration – This is one you’ve probably never heard of – Liquid Aeration

Whatever Lawn Aerator you choose should depend on the size of your lawn – and your budget 🙂

In the end, they all serve a similar function – which is to loosen up soil and dirt so the roots of the grass can absorb more air, water, and nutrients.


How To Aerate Your Lawn (3 Steps):

 

Step 1)    Prepare Lawn for Aeration

So how do you aerate your lawn?  Before you can aerate your lawn, you must do some simple preparations. Go out into your lawn and see how dry your soil is. Aerating “dry soil” can be a troublesome task, and it is certainly not optimal if you wish to aerate your lawn properly.

It’s recommended to aerate your lawn the day after it rains, or if you can’t wait for the rain, simply water your lawn the day before and let the water saturate the soil.

Mowing your lawn before aerating also helps the process. The grass height being shorter makes it easier for you to see your progress and clean up the lawn after the aeration is done.

Step 2)    Select the Best Aeration “Method”:

There are three different methods for aerating lawns: Plug aeration, Spike aeration, and Liquid aeration. Select the method that is best for your lawn size and your budget.

1)  Plug Aeration

Plug aeration involves the process of making a fairly large hole around 1/2-3/4 inches in diameter and up to 6 inches deep. This will remove part of the soil from the roots and is known to improve the overall structure of your soil more than spike aeration.

Plug aeration is ideal if you’re only aerating once a year. One of the downsides to this type of aeration is that if you are not using a high-powered automatic plug aeration device, it is a reasonably labor-intensive job. But worth it.

2)   Spike Aeration

Spike aeration punches small holes into the lawn, approximately 1-2 inches deep. The advantage of spike aeration for your grass is that it is not as labor-intensive as the plug aeration method.

Spike aeration can be done by using manual spike tools or by pulling a spike roller behind a riding lawn mower.

Because spike holes are generally not as big or as deep as plug aerators holes, your grass will be less impacted and can heal and recover quicker than plug aeration.

The disadvantage of spike aeration is that it is a short-term solution, and your soil will likely become compacted again in as little as 4-5 months.

3). Liquid Aeration

The third type of lawn aeration, which is relatively new, is called Liquid Aeration. Using the Liquid Aeration method, you apply a chemical treatment to the lawn.  

What is the chemical used for Liquid aeration?  The chemical process for liquid aeration involves using two 100% organic compounds, which are applied to the lawn.

The first product in Lawn aeration components is a wetting agent from a South American plant extract that helps water penetrate hard clay soils. The second compound is a microbial package used to eat away at the thatch layer of your lawn.

The liquid method has not been tested as much as the other two aeration methods, but it has been proven to improve water retention more than before this treatment.

Liquid aeration will add helpful substances to your lawn that are entirely safe for use around small children, pets, and other animals.

Step 3)   Select “Type” of Lawn Aeration Equipment:

The Three Types of Lawn Aerators:  Manual Aerators, Lawn Aerator Shoes, and Machine Equipment Aerators.

1)   Manual Lawn Aerators

Manual aerators are aerators with sharp protrusions that you use manually (by hand) to push or poke holes into the lawn.

This can be something straightforward like a pitchfork or a manual aeration tool like the one shown above. Manual aeration is practical for small grass areas, where you can move around the lawn, punching holes into problem areas where the soil needs aeration.

A more recent manual lawn aeration tool is the Agri-Fab spike roller.  With this tool, you Roll the lawn while the spikes punch holes into the turf.  The spiked roller is 16″ wide and punches 2 1/2″ holes into the turf for an effective and quicker means of aerating large areas of lawn.

Another popular tool for manual aeration is the Lawn aeration tool from “Yard Butler.”  This turf plug core device has a handle like a pitchfork that allows you to aerate a small section of lawn that needs attention.

You stand on the tool, like a shovel, and lift turf plugs out of the lawn, to provide much-needed oxygen, water, and nutrients to the soil.

This is a much faster and more effective method of aerating your lawn than a pitchfork, which pokes holes in the turf.

2) Lawn Aerator Shoes

Lawn aerator shoes are exactly what they sound like. They are shoes that help aerate your lawn as you walk on top of it. These spiked shoe adapters have metal spikes on the bottoms that can range between 1-2 inches in length.  

Lawn aerator shoes are desirable for those who own and wish to aerate a small lawn but are not ideal for those with medium or large lawns.

Here’s a good tip or method for using this method. When you are mowing your lawn, you can mow the lawn while wearing these shoes. Double tasking.

We rate this method as an excellent economical choice for smaller lawns but one of the least effective means for thorough or lasting lawn aeration.

3) Machine Lawn Aerators

The last type of aeration is considered the best means for lawn aeration.  With machine aeration, you will need powered equipment to achieve it, generally by the use of a riding mower.

Machine aeration makes the aeration process simpler and quicker. The machine lawn aerators are sold in both spike and plug aeration versions.

Whichever type of lawn aeration you choose, you will have an easy time gliding over your lawn.

It is always advised with any aeration – to aerate your lawn with moist soil, but with a half-good lawn aerator machine, you won’t need to be quite as concerned with having the soil fully moist.

The machines are easy to use and will involve you walking over the lawn in a straight line. Even with a machine, you may need to pass over some areas of the lawn more than once.


Lawn Treatment after Lawn Aeration (Tips)

If you have a mulching lawnmower, we recommend leaving the aerated spikes or plugs on the lawn when completed and “mowing” the debris as you mow the lawn, sending valuable mulch back into the soil.

If you have areas of the lawn that have gone patchy or even bald, reseeding the lawn after aeration is a perfect time. You should immediately seed your lawn after aerating it, and you should notice that the grass in these areas will grow greener and faster than it usually does.

Finally, we suggest adding a seasonal (Spring or Fall) fertilizer to the turf after aerating the lawn.  This will easily penetrate the lawn down to the root level at the opportune time.

(FAQ) How To Use a Lawn Aerator:

How can I tell my Lawn needs to be Aerated?

This can depend on a lot of factors. The first one is how much activity your lawn gets. Are you and other people such as family members, neighbors, or friends constantly using the lawn?

Do you have any pets or animals that enjoy the lawn? For heavy traffic lawns or yards with lots of clay.

If your soil is compact like clay or overly dry, your lawn is the perfect candidate for aeration. If your grass is not growing as full and green as it has in the past, this could be an early sign that it’s in desperate need of aeration. Aeration is also great for building turf, which in turn keeps weeds from taking over.

What is the best time of year to aerate a lawn?

The optimal time to aerate your lawn will be whatever time of year that most things are able to grow and rebuild. Aeration can damage the roots of the grass and the grass needs to be at the right time of year to be able to recover and grow back properly.

This can depend on your location, but any time in the Early spring or the Early fall is the optimal time for lawn aeration. Aerating in the colder months or the heat of the summer is not advised, as it is hard for the grass to heal and recover in these weather conditions.

Most fruit and vegetables will not grow in the winter. Likewise, it is harder for grass to combat these weather conditions, and it is certainly not ideal for aerating.

Conclusion

You will need to decide what type of aeration is right for your lawn and lifestyle as everyone’s lawn and lifestyle are different. What type of aerating device is right for you can depend on how much labor and time you would like to spend aerating your lawn and how much money you would like to spend on an aerating tool.

The size of your lawn will also be a huge factor in what type of aeration is practical. If you have a very large lawn, aeration by pitchfork is not practical at all and could take you more than a day to properly aerate it!

The time of year and weather conditions should also be taken into consideration. You wouldn’t want to aerate your lawn at a sub-optimal time of year and have your aeration process not so much benefit your hard work outside!

If the weather is very hot outside, you might aerate your lawn once and think, I’m never going to do that again! If you find aerating your lawn too labor-intensive, you might also get discouraged from aerating the lawn again.

You should also decide and know if your lawn truly needs to be aerated or not. Chances are if you are reading about aeration, there is a good chance your lawn is in desperate need of aeration! But if your grass is full, thick, and green, you can probably wait some time until you will need to aerate it.

Consistent mowing and watering of your lawn can be just as important as aerating and can make or break having your lawn look fresh, lush, and green!
