Aeration Options

Aeration: one word that can mean several different things. What form of aeration is best for your lawn?

Let’s explore a few different types of aeration: liquid aeration, core aeration, and aeration with overseeding.

1.  Liquid Aeration

How does liquid aeration work? This form of aeration creates microfractures in the soil of your lawn, causing openings that allow nutrients, air, and water to penetrate the grass more easily.

Liquid aeration has several unique benefits:

  • The process is clean and does not leave small plugs of soil on your lawn.
  • Lawns are fully covered and no amount of yard space is left without treatment.
  • It penetrates more deeply into the soil than other forms of aeration.
  • No underground fences or irrigation heads are hit during aeration.

2. Core Aeration

In core aeration, a machine removes plugs of soil from a lawn. This reduces compaction, breaks through the thatch layer, and allows nutrients to reach the roots of the grass more easily.  Pictured is an example of what a yard looks like after a core aeration.  The small plugs of soil pulled up by the aeration can be seen.

In certain soil and turf conditions (compaction and heavy root mass), core aeration is a better option than liquid aeration.  Core aeration is also used with overseeding (covered below).

The main goal of both liquid and core aeration is to allow oxygen, water, and nutrients to reach the root system of your grass, creating a stronger lawn. View our past blog post to learn more about the key benefits of aeration.

3. Aeration and Overseeding

Overseeding will be more effective when done after a core aeration.  When doing a core aeration before overseeding, we cover a lawn three times. This triple core aeration allows for greater seed to soil contact.

Fall is the perfect time of year for overseeding. See our previous blog post if you are interested in learning about the overseeding process.
