Aeration improves soil health, enhances water and nutrient absorption, and promotes stronger grass roots.

When it comes to combatting the effects of soil compaction, core aeration does a far better job for a longer period of time—because it actually removes dirt rather than just pressing holes into it. By taking dirt out from under your lawn, core aeration allows more light, air, water, and nutrients to penetrate into the soil below and help your grass’s roots grow even stronger.

Several signs indicate that your lawn may require aeration. If you notice water pooling or runoff after rainfall, it suggests poor water infiltration, and aeration could help. Compacted soil may cause grass to thin out, turn yellow, or struggle to grow. Additionally, the presence of a thatch layer, which is a buildup of dead grass and debris, can indicate aeration is needed to alleviate thatch and promote healthier grass growth. Monitoring these signs can help you determine when your lawn would benefit from aeration.

Aerating a lawn before seeding it or adding new grass seed is a smart decision. By loosening up compact soil and allowing it to take in more air and water, your seeds will have an easier time establishing roots and growing. Aerating beforehand also means your seeds will have better contact with the soil, so more of your seeds have a chance to germinate. If you do plan to aerate your lawn before seeding, aerate about two days before you plan to start seeding.
