Lawn aeration is a process by which plugs of soil and thatch are removed from a lawn to promote the exchange of air between the soil and roots. It is a process that Wilson Landscaping only recommends if a lawn truly needs it. Soil compaction can come about as the result of a variety of factors, from the natural effects of weather to other causes such as walking or playing on the lawn, or the use of heavy equipment during a period of construction. When a lawn is compacted, infiltration of water into the soil becomes restrained, and the roots do not function optimally. This can all be avoided with timely lawn aeration.
