Core Aeration is one of the best things you can do for your lawn. It is the process of making thousands of holes in the turf to open up the soil and break up thatch. The core removed by the aerator "melts" back into the lawn and immediately begins to improve thatch breakdown and begins to stimulate microbial activity in the soil. This is helps fight several diseases that can negatively affect your lawn.
What Does Aerating Do?
The root system of your lawn is constantly renewing itself by sending out new growth. This new growth needs loose and open soil. If your lawn is compacted, has a lot of clay, or is saturated with water, the new roots will stay near the surface or grow in the thatch layer. Aeration breaks up compacted, heavy soils giving the roots a place to go. Water penetration will be better and rooting will improve as well.
Who Should Get Aeration And How Often?
Every lawn can benefit from Core Aeration. It is suggested that a lawn be aerated at least every other year, but preferably every year. There is no bad time to have your lawn aerated. Spring/Fall is often mentioned as a "better" time only because of the high level of activity of the root system.
Will Aeration Control Thatch?
Core Aeration brings cores of soil up from below the lawn’s surface. We recommend that these cores be left on the lawn. By allowing these cores to mix back into lawn surface, these cores add back microbial agents which are needed to control thatch. This is not an immediate fix for a serious thatch problem, but is the best way to manage a thatch condition or help prevent thatch from becoming a problem.
