Why Lawn Aeration Is Important

Mar 14, 2019

Giving Your Turf a ‘Hole’ New Life


It is recommended that homeowners aerate their lawn once every single year, whether that be in the spring or the fall, depending on your location. Why? Because aeration is one of the best things you can do for your lawn! 


Core aeration is the removal of small cores of soil and thatch (the layer of living and decomposing organic debris between the soil surface and green vegetation) from your lawn with specially designed equipment. A series of hollow coring tines are rolled over the lawn, puncturing its surface and systematically removing small plugs of soil and thatch from the lawn. The removal of these plugs allows air, water and nutrients to reach the root system of grass plants much more effectively. In turn, both fertilizer and water use become more efficient. This contributes to a healthier, deeper root system that enables the grass plants to better overcome stress caused by insects and disease.


Plugs should be left on the lawn following aeration, as they contain soil microorganisms that will help break down thatch. These plugs disappear in a short period of time when left on the surface of the lawn.


You may be wondering: why should I aerate my lawn? Weed Man has got you covered with all the information that you need!

1. Aeration Promotes Healthy Grass


Aerating your lawn allows vital nutrients, water, sunlight and oxygen to sink in and reach the root system of your lawn. This will promote a healthy and deep root system, giving you a lush green lawn that is better equipped to defend against the intrusion of unwanted weeds and grasses.


2. Aeration Relieves Soil Compaction


This is especially key if your lawn experiences a lot of foot traffic. The increased foot traffic during the summer months (from pets, family and friends) can leave your lawn compacted due to the weight and pressure. Pulling out the small cores of soil helps your lawn release the added stress and tension. If you don’t loosen the compacted soil, it won’t allow new growth and your lawn will begin to dry out. If your soil is compacted, your lawn will experience what is known as “runoff,” therefore when it rains, or when you water your lawn, it won’t be able to penetrate through the dense soil layer.


3. Aeration Reduces Thatch


Thatch is a layer of organic dead and living shoots, stems, and roots that builds up between the grass and soil surface. While a little bit of thatch can be healthy, anything over ½ an inch must be removed because it can reduce the amount of sunlight, water and nutrients that can penetrate the soil.


4. Aeration Promotes New Growth


It is recommended for homeowners to aerate their lawn before fertilizing and seeding. This is because it gives the granules and seeds a better opportunity to take hold and penetrate the soil. Aeration also ensures that the roots of your lawn have more room to move and grow.
