Lawn aeration is the practice of removing plugs of soil from your lawn turf.
If you haven’t done this yourself, I’m sure you’ve seen your neighbors lawns with holes in their turf and little plugs of soil spread out over their turf.
If you have never done this to your lawn you may be wondering: Why do people aerate their lawn? Do I need to aerate my lawn?
We’ll cover the main benefits of lawn aeration and how it helps you achieve a beautiful green lawn.

Reasons to aerate your lawn
Aeration allows air, water, and nutrients to reach roots
These spaces in your turf allow the nourishment your grass needs to penetrate deeply into the soil down to the root level and become fully absorbed. If your soil has become compacted, more of your fertilizer and rainwater will run off your lawn before it is absorbed.

Aeration helps with soil compaction
The soil in your lawn can become heavily compacted naturally over time or with heavy use. Children playing on your lawn, sports played on your lawn, guests to your cookouts, and riding lawn mowers can all compact your soil. Soil compaction can prevent water and nutrients from reaching the roots. It can also impair healthy root growth because it is harder for roots to spread.
Aeration helps with lawn thatch
Thatch is a layer of dead and living grass stems and roots that naturally occurs in lawns. Over time, your layer of thatch may grow faster than it can decompose. When it becomes too thick, it will prevent water and nutrients from soaking through to the root level. Aeration not only helps your grass roots, it will help open up the thatch layer to air and help it decompose naturally.

Aeration helps with overseeding
Overseeding is the process of spreading new grass seed on an already established lawn in order to fill any patchy areas and get a thicker turf. When you aerate first, you open up the soil for new grass seeds to fall into and germinate. You will get better results than you will when you seed on compacted soil.

The best time to aerate your lawn
Fall is usually considered the best time to aerate your lawn. Aerating in the fall allows the soil to open up and absorb nutrients while your grass prepares itself for the cold winter. When you aerate and fertilize your lawn in the fall, your grass will be healthier the following spring.
We hope this has helped you understand the benefits of aeration so you can have a healthier lawn.
