Aeration helps alleviate compacted soil and control thatch.
When your soil is compacted, the grass roots are shallow at the base, and the grass can’t get the needed nutrients to thrive. By relieving compacted soil, you allow healthier grass to take root and grow unrestricted.
Thatch is a combination of organic matter that accumulates around grass in a lawn, as a result of poor soil aeration and drainage. Too much thatch can result in disease and a less-than-optimal environment for grass growth.
