Compacted soils stunt turf roots resulting in a lawn poorly suited to handle drought. Compacted soils have a low oxygen content and will repel water when dried out. Aeration breaks up compacted soil, improving the soil’s ability to absorb water and oxygen, and consequently improves root growth.

Thatch is an undecomposed layer of roots and stems that lies between the soil surface and the green top growth of the turf. A thin layer of thatch (1/4-1/2”) is beneficial to the lawn, protecting the roots from extreme heat and cold. Over 1/2” of thatch creates a problem by acting like a sponge and robbing the grass roots of moisture. Heavy thatch also serves as a prime breeding ground for lawn damaging insects like chinch bugs and bill bugs. Aeration will improve microbial activity in the soil which results in breaking down the thatch naturally.

Aeration is an important part of a good lawn maintenance program. Depending on soil conditions, some lawns will need aeration more often than others. Your lawn technician will inspect your lawn and help you decide when to aerate.
