About Core Aeration
If you’ve ever seen a farmer plow a field, then you’ve seen aeration in action. In short, “aeration” is the act of getting air down into the soil.
Farmers figured out many centuries ago that loosening up the soil and getting more air down to the root zone will have huge benefits to the crops. This simple truth has not changed and farmers still plow the fields every year before planting the crop.
Your lawn is not much different than a farmer’s crop. It is a large number of plants growing in a prepared soil base. We don’t plow the grass, because we would cause enough damage to need complete re-seeding. Instead, we use a core aerator, which has a similar effect with far, far less damage.
