Maintaining a lush lawn is an essential part of owning a home; however, it can be overwhelming. Thatch, a layer of dead grass and organic matter, can hinder the absorption of nutrients. Removing thatch, also known as dethatching, is crucial and should be done very year or two. On the other hand, core aeration improves soil aeration and water movement. The decision to dethatch or aerate depends on the lawn's condition. Thin thatch layers benefit from aeration, and thick thatch layers need dethatching. Other factors that influence the approach are regular maintenance and the grass type.
