One of the ways homeowners can keep their lawns looking lush and green is to aerate the turf when the need arises.
Aerators perforate the soil with small holes. These holes allow air, nutrients and water to penetrate all the way to the roots, helping them grow deep and strong. Deep, strong roots are essential to healthy, lush lawns.
While aeration can help many lawns, not every lawn will necessarily need to be aerated. Lawns that get heavy use, such as those that are often played on by children or pets, will likely benefit from periodic aeration. Feeling the lawn also can help homeowners determine if it needs to be aerated. Lawns that dry out quickly or feel spongy may be overcome with thatch, which can prevent lawns from getting the air, water and nutrients they need to thrive. Lawncare professionals recommend aerating lawns that contain thatch that is more than one-half inch. Thatch also can foster grub infestations, providing another benefit to removing it and aerating a lawn.
When to aerate depends on the type of grass. Homeowners should consult with a lawncare professional about the best time to aerate their particular lawns, but it’s generally recommended that cool-season grasses be aerated in early spring or fall, while it’s best to aerate warm season grasses in late spring.
