The answer to 'what is aeration' is aeration is the process of perforating the soil with small holes to allow air, water, and nutrients to penetrate the grass roots. This is an important lawn care practice that helps to alleviate soil compaction and improve the overall health and appearance of your lawn.
Aeration is typically done with a specialized machine that punches holes in the soil, either by using hollow tines that remove small plugs of soil or solid tines that simply poke holes. This process allows oxygen to reach the roots, which helps them grow deeper and become more drought-resistant. It also allows water and fertilizer to better penetrate the soil, leading to a thicker, greener lawn.
