Aeration involves creating small holes in the soil to allow air, water, and nutrients to penetrate to the grass roots. This process alleviates soil compaction, enabling healthier root growth. Consider it like loosening tightly packed earth to allow roots to breathe and thrive.
Proper soil aeration is crucial for a healthy lawn. It facilitates better water absorption, reduces thatch buildup, and improves the overall vigor of the grass. Historically, manual methods were employed, but modern techniques provide more efficient and consistent results.
