Often viewed as one of the most important things a lawn can benefit from, a core aeration service really is a breath of fresh air for your lawn. Aeration is performed using a special machine that removes small cores of soil about the same size as your index finger. These cores are then left on the lawn and decompose quickly under mowing and precipitation.
Aeration is recommended annually, with the best times being in the Fall or Spring, when the lawn is actively growing. Combined with other cultural practices, an annual aeration will give you a thick, healthy, and robust lawn, especially when combined with overseeding.
