Core Aeration every fall is an important part of having a healthy lawn. Core aeration is the process of perforating the soil mechanically, which removes small plugs of soil and thatch. Aeration is important to allow water, air, and nutrients to more easily reach the roots of grass plants, loosens compacted soil, and helps to reduce thatch. This will help the lawn develop stronger and deeper root systems, thus allowing a stronger and more durable lawn.
Core Aeration is done by running an aerator across your lawn. The aerator will pull “plugs” out of the soil which are typically 1” to 1 ½” deep and are spaced approximately 4” apart. The plugs will remain on the lawn and should not be raked up. This is important for the lawn because the decomposing plugs increase microbial soil activity, which helps to reduce thatch.
Lawns can benefit from aeration yearly. Additionally, lawns with compacted soil in newer developments, and lawns with high traffic from children and pets, should definitely be aerated. After a very hot and dry summer, there is no better thing for a lawn than a core aeration. Overseeding should always be done with core aeration, giving the seed a much better probability of germination.
