Core Aeration is simple, cost-effective and very beneficial to you lawn. It helps to reduce soil compaction, promote root growth and reduce a buildup of thatch. Lawn Aeration will greatly improve a lawn if scheduled on a yearly basis. We recommend one time in spring and again in fall. Aeration allows water and fertilizer to get down to the root zone. It will help to reduce the thatch layer which blocks water, oxygen and fertilizer from penetrating to the root of the plant.
