1. Reduces thatch build up in your lawn: Too much thatch is harmful to your lawn. Most lawn diseases (fungus) and insect infestation begins in the thatch layer of your lawn. Aeration breaks up that layer and allows microbial activity to become active which naturally breaks down thatch.
2. Allows air, moisture and nutrients deeper into the root zone of the plant: Air, water and nutrients are essential to a healthy lawn... Aerating opens up the soil allowing these to take place in the most needed area.
3. Loosens and opens up compacted soil for deeper root development: Pulling cores from your lawn opens the compacted soil and encourages the roots to move deeper into the soil promoting a greener, healthier lawn.
