Aeration involves using a machine known as a lawn aerator to create holes in the soil. There are two main types of aeration: core aeration and spike aeration. Core aeration removes plugs of soil, while spike aeration simply pokes holes into the ground. Core aeration is generally more effective as it reduces soil compaction and enhances root growth more efficiently.
Over time, soil can become compacted, especially in areas with heavy foot traffic or clay-heavy soil. Compacted soil restricts the movement of air, water, and nutrients, making it difficult for grass to thrive. Lawn aeration alleviates this compaction, promoting healthier, greener grass. According to studies, aeration can improve soil structure, enhance water infiltration, and reduce water runoff and puddling.
