What is a Lawn Aerator?

A lawn aerator is a simple device that used to break up the compacted soil to allow the air, water and key nutrients get penetrate deep into the roots of the plant/grass. It helps the grass and plants to grow better by alleviating the soil compaction. 

How to Choose the Best Lawn Aerator for your Lawn?

To purchase the best lawn aerator, you have to keep a detailed list of some of these factors. Let’s have a look at it.

1) Types of Aerator to be used?

In general, there are two types of lawn aerators which include spike aerators and plug aerators (by depending on the type of soil and the lawn area to be aerated)

Spike Aerators 

These are designed to punch holes in the soil and are mostly used for light grounds but not for heavy compacted soil. These are manual aerators and can be used at any time of the year, especially during fertilization or preparing the lawn surface for overseeding.

Plug Aerators / Core Aerators 

These are designed to punch holes and remove the soil or debris from the surface. It is most suited for compact soil or with heavy clay soil. These aerators can be electrical, battery or gas based and that works well when the soil is moist but not saturated with water.

Kinds of Lawn Aerators:

By depending on these two types, there are various kinds of lawn aerators available in the market. Before buying a lawn aerator that suits best for your yard, you have to understand its types and their usage. It works either by pushing or pulling across the garden or lawn. 

A) Spike Aerators / Manual Aerators:

There are various manual lawn aerators available in the market. They look like a garden fork with open tines or spikes to punch holes in the soil. These handheld or manual aerators are inexpensive and works best for the small yards but it is time consuming and labor intensive (use your hands or feet to push the aerator). 

1A. Spike (tine) Aerator:
  • This spike or tine or step aerator is ideal for small-sized lawns or yards but not for medium or large-sized lawns/yards. 
  • It resembles like a fork with 4 – 5 spikes that help to loosen the compacted soil. 
  • You have to place your foot on the foot hole and then push down so that the spikes sink into the ground. Then pull it out and repeat the same process throughout the lawn. 
2A. Spike Core Aerator:
  • This spike core aerator works well for an older lawn which is densely compacted soil and has a lot of debris. 
  • It is designed like a garden fork with two sharp tines of about 9 – inches apart that helps to penetrate deep into the compacted soil.
  • It also removes 2 – 3 inch cores of thatch and thereby stimulates the growth of grass root. 
3A. Spike Aerator Shoes:
  • If you love gardening or mowing, then you can choose a pair of spike aerator shoes which works effectively in aerating your yard. 
  • Simply strap these sharp shoes onto the feet and walk around by performing gardening chores so that those sharp spikes of the shoe will poke into the soil or yard. 
  • Make sure to handle these shoes with care and avoid playing games.

B) Plug / Core Aerators:

Most of the gardeners prefer this as a most effective and easy method of aerating the lawn. It uses either electricity or battery or gas to fertile the soil. There are various types of aerators that are widely used to aerate the lawn. Let’s we know them in detail…

1B. Push Style Roller Aerator:
  • This aerator is helpful to those people who don’t want to expend a lot of energy. 
  • It looks like an old manual style roller lawnmower and suitable for small to medium-sized yards rather than large-sized lawns. 
  • It is made from tubular steel with two sturdy plastic wheels and a tray that contains steel sharp spikes to dig into the soil up to 1-inch depth. 
  • Remember that it is not designed for a heavy compacted soil or uneven terrain. It is meant for a quick and easy tool for maintaining your lawn.
2B. Tow Style Plug Aerators:
  • This plug aerator is the best one to use for larger lawns which uses a tractor, ATV, or riding mower. 
  • This aerator comes in different sizes that range from 42 – 48 inches. 
  • It is made up of heavy-duty steel with a steel reinformed towing bar. 
  • The weight will help to increase the penetration level for compact soil areas and thereby keeps it well balanced. 
3B. Gas Powered:
  • These gas powered models are suitable for professional or commercial purpose.
  • A gasoline engine placed over the top of the knives to provide the weight needed to pull cores. 
  • It is narrow in width when compared to tow behinds and also loud and emit exhaust fumes.
  • The best thing is that it aerates the lawn, cleans the grass faster than a tractor or ATV. 

2. Power

Always remember that the more power the lawn aerator has then the longer will be its lifetime and also it aerates the harder soil. So, choose the one which has more power rather than small electric aerators that dead after a couple of usages.

3. Width of the Blades

To spend less amount of time on lawn aeration, you have to choose the proper width of the aerator blades. The wider the aerator then the time taken will be less. The width of the blades depends on the type of soil.  The width of the aerator plays an important role in aerating the lawn on a single pass and thereby saves time. For example, an aerator with 4 feet width will aerate 33 percent more soil when compared with a unit measuring 3 feet wide aerator. 

4. Body Material

The body can be made of plastic or metal in which the plastic aerators weighs less and won’t get a problem of corrosion while as the strength and durability of the plastic is less than the metal. So, choose the best one that suits you. 

5. Knives

Some aerators have needles and while others have spikes to pierce the ground. Also, there are some other aerators that contain special knives to clean the old grass and weed. So, choose the best one with perfect knives for lawn aeration. 

6. Grass Collecting Bag

Some people prefer to have a grass collecting bag rather than cutting and cleaning the lawn after aeration while some others leave the grass to compost and make the soil richer. 

7. Cost or Price of a Lawn Aerator

We already know that lawn aerators are used twice or thrice a year so that wise decision is to buy pocket-friendly aerators. The size of the yard which has to be aerated will decide the type of aerator to be purchased and thereby its price.  You can get a reasonable aerator shoe for about $20 and it can be cleaned or stored quickly. Handheld manual aerators cost twice then the aerator shoes whereas the large aerators (lawn tractor or tow models) cost $150 to $200. 

8. Warranty / Reliability

Just like most of the garden equipment, this lawn aerator has warranty given by the manufacturer’s. Although they don’t cover any damages that caused to the equipment due to natural wear and tear or any user error. These aerators mostly come with 2-year warranty and thereby cover flaws in the manufacturing process or materials. 

9. Maintenance

Maintenance is very essential to keep any equipment clean, safe and to ensure a long life span. At the end of the usage, clean the equipment thoroughly and apply oil all the metal parts lightly. Here are some tips that you have to follow after every usage of this lawn aerator to make it clean and durable. 

  • Rinse dirt or mud off the lawn aerator by using garden hose
  • After finishing your work, remove any tiny soil cores that remain in the lawn aerator.
  • Whenever the plug points lose their edge then it has to be sharpened individually with a small grinder. 
  • Oil the lawn spool, shaft and wheel hubs as needed to protect it for a longer time. 

10. Effectiveness

Everyone wants to get the best thing for the money they invested. So, make sure to check that the lawn aerator is made by a reputable manufacturer with high quality material to keep the product safe and durable that increases the likelihood of reliability across its lifespan.

11. Ergonomic Handles

Whether you’re using manual, electric or petrol lawn aerators, ergonomics plays an important role in buying the aerators. The finish on the models should be smooth to avoid straining your back or getting blisters. The quality of the wheels and handles (well positioned) is essential for the overall durability of the product. 

Why do we need to use a lawn aerator?

A lawn aerator is basically used to keep the lawn area clean and green with a healthy turf growth. We know that soil become dry and compact, particularly in the hot and humid climate which makes the soil unable to absorb air, water and other nutrients.  Here are some benefits that explain you the need to use this versatile gardening tool.

  • It alleviates the soil compaction, increases the uptake of oxygen, water and other nutrients and also removes the buildup of organic debris on the soil’s surface.
  • It strengthens the roots of the grass and thereby it helps for proper and healthy growth of grass or plants.
  • It prevents water logging issues and removes patchy or bare grass along with making the land more fertile to reseed the lawn. 
  • It creates more heat and drought resistant lawn. It reduces the water runoff which is caused due to heavy rains. 
  • Some lawns may experience human or animal traffic in which the soil become compact (unable to stick even a pencil). So, this type of lawns requires regular aeration for best results. 

The Best Time to Aerate the Lawn: To maintain a perfect garden, every gardener should have this lawn aerator and they should know how often they have to use this lawn aerator.  It is recommended to aerate the lawn for twice a year, especially for compacted soil or the soil with clay content to loosen the soil and make it absorb the water and nutrients.  The best time to aerate the lawn is during the growing seasons (before seeding). For warm – season grasses, aerate the lawn in late spring or early summer. For cool – season grasses, aerate the lawn in early spring or early fall. 

How Does a Lawn Aerator Works?

The simple mechanic in the lawn aerator is that it has rows of spikes or hollow tines which go into the soil surface by making small holes to get air, water and nutrients into the soil to alleviate the soil compaction. The process of lawn aeration will fertilize your land and make it more resistant to heat and insects to help the grass grow greener and thicker. So, aerate the lawn before reseeding or fertilizing for best results. Avoid using the lawn aerator in a dry and hot weather. 

What Steps to take before Aerating the Lawn?

  • The most important step is that you should cut the grass short which is less than 1.5 inches to make the soil for proper aeration. 
  • For proper aeration of the lawn, you have to water the land the day before aerating to moisten the soil but won’t water too much to make it wet. 
  • Be sure that all the irrigation pipes, power lines, valve boxes, and other pipes should be marked below this aeration level. 
  • Also, remove all the weeds before using this lawn aerator to prevent the spread of these weeds all over the lawn.

Before beginning the usage of lawn aerator, you have to understand what type of soil you’re dealing with. Like hard soil need stronger blades to penetrate into the soil and clay soil need longer blades for this aeration process. Another important factor is size of your lawn to be aerated regularly.  Don’t think that choosing a lawn aerator that perfectly meets your needs as overwhelming or tedious process. I hope this guide will definitely help you in understanding all about lawn aerators and thereby simplify your search. 

Frequently Asked Questions

1. Which one is best – Hand Pushed or Tractor Powered?

We already discussed that for small sized yard, you can use the aerators that are designed manually (uses muscle power to operate) which are less expensive. Also, there are lawn tractors designed for large yards to clean and fertilize the soil.

2. Difference Between Plug Aerator and Spike Aerator

Lawn aerator works by removing the plugs or cores of soil and creates opening in the soil with its spikes to make the land fertilize. Basically there are two types of aerators – plug aerator and spike aerator.

Plug / core aerator contains hollow metal tines that open up the holes, removes thatch and reduces compaction for better absorption of oxygen, water and other nutrients into the soil. It also removes cores of soil when it moved across the yard.  For best results in longer run, experts suggest us to use plug aerators. Spike aerators contain solid metal or plastic tines that used to puncture the ground. The wedge shaped tines are major drawback of these aerators why because they cause additional ground compaction in the area which is surrounding the punctures. Spike aerators vs. plug aerators – Spike aerator is used widely for seeding a brand new lawn but whereas for already established turf, plug or core aerators works well.
3. Is it best to aerate the lawn before seeding?

Yes, definitely it works best to aerate the lawn before overseeding why because aeration reduces the soil compaction, allows better absorption of moisture, air and other nutrients for root development and thereby helps for the healthy growth of the plants or grass.

4. Dethatching VS Aerating?

Dethatching is used to remove a dead layer of roots and stems where as aerating helps to open up the hole in the land by using spikes or pulls soil cores. Although, they are used differently but serve for a similar purpose (allows oxygen, water and key nutrients to fertilize the soil).

5. Does mowing right after aeration is good for lawn?

The best time to mow the lawn is right before aerating but not after aerating. The reason is that mowing the lawn up to a height of 1.5 to 2 inches before aeration will make the land more fertile and thereby helps the grass to get recovered before going for another mow. Also, avoid rake after aerating the lawn to prevent the loss of soil microorganisms and organic matter.

6. How deep should I aerate the lawn?

It completely depends on the thickness of the thatch layer and the amount of soil compaction. In general, aerating to a depth of 2 – 3 inches is preferred for the thatch less than 1 inch thick. If the lawns are heavily compacted or having a thick layer of thatch, then you can go for the depth of 4 – 6 inches under the proper guidance of professional.

7. What will happen if I don’t aerate my lawn?

If you don’t aerate the land regularly then the soil becomes compacted and thus layers of debris will build up on the soil surface which in turn effects the movement (or absorption) of water, air, fertilizers and key nutrients into the roots. Finally, they will be less or poor growth of grass or plants in your lawn. So, remember to aerate your lawn regularly to reduce thatch layer and thereby loss of soil moisture.

8. What parameters I have to check before buying a lawn aerator?

Before buying a lawn aerator, you have to go through the soil type of lawn, size of the yard and price. We know that there is no use of purchasing an aerator rake for a big yard and gas powered lawn aerator for a small garden. * For small lawn with hard soil, manual aerator with wheels suits best. * For small lawn with light soil, lawn aerator rake will work best. * For big lawn with hard soil, use gas powered lawn aerator. * For big lawn with light soil, prefer electric lawn plug aerator.
