Aeration is the process of mechanically removing small plugs of soil and thatch from the lawn to improve soil aeration. Lawn thatch is the layer of dead turfgrass between the green vegetation and the soil surface that must be removed to maintain the lawn health.

Thatch becomes worse over time as organic material gets tangled up in the grass, unless, of course you do something about it. A thin layer of thatch is desireable because it helps insulate the grass from extreme heat and cold. The cushioning effect also helps the lawn deal with heavy traffic.

 

Benefits

• Enhances water, fertilizer, and oxygen penetration for a healthier lawn
• Reduces water runoff and puddling
• Reduces soil compaction
• Improves grass roots

Why should I aerate my lawn?

After aeration, your lawn should be able to go longer between waterings. With repeat aerations over time, your lawn will show enhanced heat and drought tolerance. Lawns that are aerated regularly will be healthier, more vigorous, easier to maintain and have fewer pest problems than lawns that are neglected.


When should lawns be aerated?

Lawn aeration should be done every 1-2 years to improve the total health of your lawn. Lawns with heavy traffic or clay composition should be aerated more frequently (1-2 times a year).


What to expect

After the lawn has been aerated, the grass will be covered with small plugs. In about a week or two, the plugs will break apart and disappear. Within a week after core aeration, oxygen, moisture, and fertilizer (if applied) will enter in the aeration holes and you will be able to see actively growing roots.
