Periodic aeration is important to counter the effects of compacted soil. Especially where foot traffic wears paths into the lawn, where children play, and where heavy lawn-mowing equipment is used, compacted soil prevents air, water, and nutrients from reaching grass roots. Clay soil is more susceptible than sandy soil to compaction.

Aeration enables oxygen and moisture to reach grass roots, promoting thicker and greener growth. It provides better conditions for microorganisms to thrive and helps grass roots access the fertilizer available in the soil.

You can maximize the effects of aeration by watering the ground thoroughly before aerating. Aerating once a year is usually sufficient for most lawns. We highly recommend that you aerate cool-season grasses in early fall and warm-season grasses in spring so that you can follow immediately with your seasonal application of fertilizer and a thorough watering.
