Everything to know about Lawn Aeration

A beautiful lawn can be achieved and maintained by following a few basic lawn care practices, like mowing, fertilizing and watering. As well as ensuring nutrients can reach the soil underneath your grass, you should also make sure it is free from weeds. Aeration can be a very important part of maintaining a healthy lawn as it allows air and water to penetrate thatch and build-up. Aerate your lawn to eliminate thatch and create a healthy, green lawn.

True lush, vibrant green lawns require a great deal of work and dedication. If you hope to succeed in maintaining green lush lawns, there are a few steps you must follow. One of the most important is aeration, which is often overlooked. It might be because it can be physically demanding and time-consuming.  It’s possible that some folks don’t think they need it. Many people may not even fully comprehend what it is.

How does lawn aeration work? Would it be beneficial for your lawn if it were aerated? The purpose of this article is to answer these questions and many others.

Exactly what do you mean by aeration?

In aeration, air, water and nutrients are allowed to penetrate grass roots through small holes perforated into the soil. It allows the roots to grow deeper, which produces a more healthy, vigorous lawn. Aeration is primarily undertaken to prevent soil compaction. The compaction of soil blocks the flow of air, water and nutrients in the soil due to the accumulation of solid particles. Under the grass surface, heavy organic debris or excess lawn thatch can further remove these essential nutrients.

Does Your Lawn Need Aeration?

How to determine if you should aerate your lawn is a common question from homeowners.

If your lawn contains any of the following, it may benefit from aeration:

  • The track is used extensively, such as for neighbourhood games or races. Compression of soil occurs as a result of children and pets playing in the yard.
  • The facility was part of a recently constructed home. It is common for newly constructed lawns to have their top-soils removed or buried, while the grass established on the subsoil has been compacted by construction traffic.
  • Dries quickly and has a spongy texture. This may indicate that your lawn has a lot of thatch. A few inches of lawn can be removed by digging with a shovel. (4-inch to be precise!) It is recommended to aerate soils with thatch layers exceeding half an inch.
  • A sod-based establishment exists, as does soil layering. Layering soil consists of spreading soil with a finer texture over soil with a coarser texture, imported sod included. In these layered soils, water is retained due to their finer texture, interfering with drainage. As a result, roots fail to develop and conditions are compacted. As aeration breaks up the layers in the soil, moisture is permitted to penetrate the roots more easily.

Consequently, if your lawn is fairy described by any of the above statements then aeration is what you should look upon. In spite of having such a kind of lawn as discussed above, if you haven’t made up mind to aerate your lawn then read on. In fact, aeration has its range of benefits.  After comprehending this vivid range of benefits of lawn aeration, you will definitely reconsider your decision of still not aerating your lawn!

Why Aeration is Beneficial for Your Lawn?

Does aerating your lawn make sense? In this post, we will walk through lawn aeration’s key benefits:

  • Maintains the health of the grass:

Aerating your lawn is one of the best ways to improve the overall condition of your grass. Providing the root zone with more air, water, and fertilizer is the purpose of core aeration. Air, water, and nutrients improve the health of the turf, allowing it to develop deeper roots.

  • Ensure strong root growth:

Your grass has a better chance of absorbing nutrients, air, and water after aerating. Thus, aerating helps the grass roots grow, especially when top-dressed with quality fertilizer. It will be better for your grass as well as your soil.

  • Provides relief from soil compaction:

If your lawn’s soil is compacted, it will not receive air, water, or fertilizers. This will result in dead spots, patches, and/or thinning of your lawn. Soil density is decreased when cores are removed during the aeration process, which relieves compaction.

  • Excess thatch will be removed:

Your lawn will be much more aesthetically pleasing with routine aeration. When you accumulate thatch on your lawn, it can rob your turf of moisture and nutrients. Through core aeration, microbes from the soil decompose the thatch layer above the soil level.

  • During droughts. Aeration can help the soil retain moisture if there is no rain coming for several months, or if you don’t want to water your lawn all the time. Your lawn may be more resistant to dry spells after aerating if it currently is susceptible. As such, your turf will be well-prepared for those long, warm summers – always the most stressful time of year for lawns – regardless of your location.
  • Resulted in less runoff and ponding. An aeration might help you if you’re experiencing runoff or ponding after rain.
  • You will have a better looking lawn. Every time you aerate your lawn, your grass will appear fuller and more even.
  • Overseeing operations are extremely benefited. It is beneficial to core aerate an existing lawn both before and after you plant new seeds. Seed-soil contact is augmented by soil cultivation, and the moist and protected environment is optimal for the growth and development of seedlings.
  • Enhances pH levels. After core aeration with lime or sulphur, the pH is changed deeper in the soil profile. So that nutrients can reach the root system, the turf will be able to utilize them effectively.
  • It allows grass to go dormant in the winter and to spring green again. By combining fall aeration with fall fertilization, your cool-season grass will be in good shape before it goes dormant. When you fertilize before aerating, the nutrients will soak in better. Aeration and fertilization plan in the fall allows cool-season grasses to be protected from summer drought stress, while offering the grass the necessary time to recover before the first winter frost.
  • Weeds can be controlled and prevented with aeration: Lawn aeration is intended to keep weeds from taking root in the lawn by loosening the soil and disrupting the roots, thereby pushing out undesirable plants. In addition, aeration allows weed killers to penetrate the soil better and be more effective, just like air, water, and fertilizer.
  • Provides better drainage and water run-off: How many times have you seen flooding on your lawn? You can imagine what will happen when lawns with poor aeration experience several days of heavy downpours. Fortunately, that’s easily remedied with aeration, which is another excellent reason for doing aeration. There will be better drainage, ensuring that puddles and permanent stagnant water areas won’t form. You can also aerate troublesome areas if you see puddles on your lawn after watering – any aeration in these spots works wonders.

We have talked a lot about core aeration but what is actually meant by core aeration?

It involves mechanically removing plugs or cores of soil and thatch from a lawn using a machine (a lawn aerator) that has hollow tines. Reduced soil compaction leads to increased penetration of oxygen, water, and nutrients by core aeration. In addition to aerating a lawn, there are other methods. A lawn aerator, for example, drives solid tines through the soil. The problem is that this method is not considered as effective as core aeration. The core aeration method is considered more effective, since larger hole diameters are created. A pitchfork could also be plunged into the grass every X square inches, but most people won’t be able to do that.


With all these fantastic benefits, every lawn should be aerated regularly. Nevertheless, experts suggest aerating your lawn only once or twice a year. If heavy snows have fallen or parts of the lawn are experiencing high traffic, then you should aerate them. However, you do it, you do not have to do it frequently, which is a relief considering how hard it is.
