Core aeration is a great way to rejuvenate your lawn. During the process, an aerator punches out plugs of soil across your lawn. This creates pathways through which air, water, and fertilizer can more easily travel to your turf’s roots. This allows them to grow stronger and deeper, keeping your lawn lush, vibrant, and resilient against the elements year round. After the plugs are removed, they are left to dissolve on your lawn during rainfall and watering. Eventually, they mix with the thatch layer to help it break down, which makes it easier for moisture and nutrients to reach your turf’s roots and helps discourage harmful insects from settling in the thatch.
