Why is Lawn Aeration Important?

Aerating your lawn is one of the most important things you can do to ensure healthy growth and vibrant grass. If you are considering aeration and seeding for your landscape, it’s important to first understand if it’s needed. In this blog, we will discuss:

Aeration vs Seeding

While aeration and seeding go together, both of these aspects can be done separately. Learn the differences between the two:

What is Lawn Aeration?

Lawn aeration is the process of pulling out small plugs of soil from your lawn in order to improve air circulation, water infiltration, and drainage. It also helps reduce thatch buildup and provides a way for nutrients and water to reach the roots of your grass more easily. Aeration also relieves compaction, which can be caused by heavy foot traffic or even just the natural settling of soil over time. Compacted soil doesn't allow roots to grow as deeply or absorb oxygen and nutrients as readily as loose, healthy soil does. As a result, grass growing in compacted soil is often sparser, weaker, and more susceptible to disease and pests.

If you live in an area with a lot of clay in the soil, aeration is particularly important. That's because clay particles are very small and tend to bind together tightly, making it difficult for water, oxygen, and nutrients to penetrate the ground. Aerating your lawn on a regular basis can help break up the clay and improve the health of your grass.

What is Overseeding?

Overseeding is the process of planting grass seed in an existing lawn. This can be done to improve the density of the grass or to change the type of grass that is growing. Overseeding a lawn that is compacted can be difficult, as the new seedlings may not be able to penetrate the ground. Aerating before overseeding can help make sure the new seedlings have a chance to take root. Overseeding is another process that can improve the density, color, and overall health of your lawn.

There are many benefits to overseeding your lawn, including:

  • Improving the density of your turf
  • Adding new cultivars or grass types
  • Enhancing the color of your lawn
  • Improving the overall health of your turfgrass

How Often Should I Aerate My Lawn?

In general, most lawns should be aerated once a year. However, the frequency at which you aerate your lawn will depend on its condition and type of soil. If you live in an area with heavy clay soil, you may need to aerate more frequently. If your lawn is in good condition and has a healthy root system, you may be able to go longer between aerations. It’s important to understand the precautions of aerating your turf too much as it can dry it out and ultimately lose the vital nutrients it needs. While aerating your lawn may take some effort, the benefits are worth it. Aeration can help your lawn better withstand drought conditions. In addition, aerating can make your lawn more attractive by promoting new growth and improving its color when done right. 

When Should I Aerate My Lawn?

The best time to aerate your lawn is in the fall when the weather is cool, and the grass is actively growing. Aerating in the fall gives the roots of your grass a chance to recover before winter sets in. However, you can also aerate in the spring if needed. Avoid aerating your lawn in the summer, as this can stress the grass and make it more susceptible to diseases like brown patch, fairy ring, dollar spot, and gray snow mold.

How Do I Aerate My Lawn?

There are two ways to aerate your lawn: manually or with a machine.

Manual aeration is the simplest and cheapest method, but it’s also the most labor-intensive. It involves using a hand-held tool to poke small holes in the soil. This can be done with an aerating fork, which has tines that are about 3 inches long, or an aerating shoe, which has spikes that puncture the soil. If you have a small lawn, manual aeration may be the best option. But if you have a large lawn, or if your lawn is particularly hard or compacted, you may want to consider renting an aerating machine. There are two types of lawn aerators available: spike aerators and plug aerators.

Spike Aerator

Spike aerators will puncture the soil with metal or plastic spikes. The advantage of this type of lawn aerator is that it’s less likely to damage the lawn than a plug aerator. However, because the spikes only penetrate the top layer of soil, they may not be as effective at breaking up compacted soil.

Plug Aerator

Plug aerators remove small cores of soil from the lawn. These cores are about 3 inches long and 1/2 inch in diameter. The advantage of this type of machine is that it can break up compacted soils more effectively than a spike aerator. But because it removes soil from the lawn, it can also damage the grass if used improperly.

Liquid Aeration 

Liquid aeration is a new process that uses a machine to inject a liquid solution into the ground, which then creates tiny channels for air, water, and nutrients to travel through.

So, what’s the difference between lawn aeration and liquid aeration? Lawn aeration is typically done with a machine that removes small cores of soil from your lawn, such as the spike and plug aerators. This leaves behind small holes that help improve drainage and increase oxygen levels in the soil. Liquid aeration also improves drainage and oxygen levels, but does so without removing any soil.

Is Aerating Your Lawn Worth it?

The answer to this question depends on the condition of your lawn. If your grass is growing well and you don't have any problems with compaction, aeration may not be necessary. However, if your lawn is struggling, aerating can help improve its health. Lawn aeration is one of those lawn care practices that many people know they should do, but few actually take the time to do. If you’re on the fence about whether or not lawn aeration is worth your time and effort, consider the following benefits:

  • Lawn aeration can improve drainage. If your lawn has poor drainage, water can pool on the surface and cause problems like flooding and waterlogging. Lawn aeration can help to alleviate these problems by increasing the amount of oxygen in the soil and improving drainage.
  • Lawn aeration can also help to improve the health of your grass. Grass roots need oxygen to stay healthy, and lawn aeration can help to increase the amount of oxygen in the soil. This can lead to a healthier lawn that is better able to withstand disease and pests.
  • Lawn aeration can also help to improve the appearance of your lawn. A healthy, well-aerated lawn will have a deeper green color and will be more lush and full than a lawn that is not aerated.

So, if you’re looking for a way to improve the health of your lawn and make it look its best, consider aerating it. It may take some effort on your part, but the benefits are definitely worth it!

Frequently Asked Questions

How Long After Aeration Can I Seed?

Overseeding typically takes place within 48 hours after aeration.

When to Apply Liquid Aeration

Just like core aeration, liquid aeration is most effective when done in the fall or spring


When to Mow After Aeration and Overseeding

If you’re only aerating and not overseeding, it’s best to wait at least a week until you mow your lawn again. If you seed after aeration, it’s important to give your lawn 2-4 weeks to give the seeds time to acclimate before mowing. It is recommended to mow your lawn to a suitable height before aeration.
