Aeration involves perforating the soil with small holes to allow air, water, and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn.
The main reason for aerating is to alleviate soil compaction. Compacted soils have too many solid particles in a certain volume or space, which prevents proper circulation of air, water, and nutrients within the soil. Excess lawn thatch or heavy organic debris buried under the grass surface can also starve the roots from these essential elements.
One of the most common questions from homeowners is how to determine if they should be aerating their lawn. Your lawn is probably a good candidate for aeration if it
The best time for aeration is during the growing season, when the grass can heal and fill in any open areas after soil plugs are removed. Ideally, aerate the lawn in the early spring or fall.
