Lawn aeration can greatly improve the overall health of your lawn. Core lawn aeration uses a specialized piece of equipment, commonly known as a lawn aerator, to make little holes in your lawn. The nickel-size holes made by the lawn aerator give your roots greater access to air, water and fertilizer. Core lawn aeration also helps control the amount of thatch in your yard, that layer of tightly woven plant material that can prevent nutrients and other items from reaching your soil. Why consider manual lawn aeration when the experts at TruGreen have specialized equipment and the know-how to help you achieve your desired results.
