Why Aerate Your Lawn
Lawn aeration is critical to the growth and health of your lawn. It helps provide a
- fuller, and
- more resilient against pests or diseases.
The main reason for aerating is to lessen soil compaction. Compacted soils have too many solid particles in a certain volume or space, which prevents proper circulation of air, water and nutrients within the soil. Excess lawn thatch or heavy organic debris buried under the grass surface can also starve the roots from these essential elements.
Aeration involves perforating the soil with small holes to allow air, water and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn.
When to Aerate Your Lawn
The best time to aerate is during the growing season, when the grass can fill in any open areas after soil plugs are removed. Ideally, aerate the lawn in the early spring or fall.
Should You Be Aerating Your Lawn?
One of the most common questions from homeowners is how to determine if they should aerate their lawn. Your lawn is a good candidate if it:
- Gets heavy use, such children and pets running around the yard contributing to soil compaction.
- Dries out easily and has a spongy feel. This could mean your lawn has an excessive thatch problem. Take a shovel and remove a slice of lawn about four inches deep. If the thatch layer is greater than one-half inch, we recommend that you consider aerating.
- Was established by sod, and soil layering exists. This layering disrupts drainage because water is held in the finer-textured soil and doesn’t seep into the roots. This leads to compacted conditions and poor root development..
