What Are the Benefits of Aeration and Overseeding


To get that dream lawn that you’ve always wanted, you need to do more than just practice proper mowing, fertilizing, and weed control. All of these things won’t benefit your lawn if your soil is compact. Compact soil occurs when soil particles are pressed together tightly, reducing the space between them. Heavily compacted soils reduce the rate of both water infiltration and drainage. It also causes grassroots to try and reach deeper, putting stress on the grass.

How Does Aeration Work?

The aeration process involves removing the core of soil from the lawn to allow air, water, and nutrients into the grassroots. This helps promote deep root growth and produce a stronger, healthier lawn.

Should I Aerate My Lawn?

One of the most common questions from homeowners is how to determine if they should be aerating their lawn.

Here are some indicators that your lawn is a good candidate for aeration:

  • Children, pets, or other types of traffic are common. Constant traffic over years can cause soil compaction.
  • The lawn was established as part of a newly constructed home. Construction equipment can cause soil compaction.
  • Water runs off and/or pools in areas of your yard. This could be caused by thatch as well. Pooling water can compact your lawn, attract fungus, disease-carrying mosquitoes, and other pests.
  • Use a shovel to check the thatch layer of your grass. If it is thicker than a half-inch then aeration is recommended.
  • Brown patches or weak-looking grass.

The Benefits of Core Aeration

Aeration has immediate and long-lasting benefits that improve the overall health and appearance of your landscape, including:

  • Deeper root growth which benefits the grass during times of drought.
  • Thicker, lusher grass that prevents weeds from taking over.
  • Faster growing grass.
  • Reduced water runoff and increased water absorption.

When is the Best Time to Aerate?

The best time to aerate depends on where you live and your grass type. Aeration should be done during the growing season of your grass so your grass can heal and fill in any holes after the soil plugs are removed.

For cool-season grasses such as ryegrass, Kentucky bluegrass, and fescues, they should be aerated in the early spring or fall.

Warm-season grasses such as bermudagrass, centipede grass, St. Augustine, or zoysia grass should be aerated in the late spring or early summer.


This is a process that compliments aeration and can do wonders for your lawn. Overseeding, simply put, is the application of new grass seeds into your existing lawn. These are usually different strains of grass than your current lawn. By adding other strains of grass that are more resistant to lawn pests, drought, and lawn disease can greatly increase the health of your lawn. Overseeding also has the benefit of quickly thickening up your lawn and filling in bare spots, creating a more uniform look while blocking out pesky weeds.
