Lawn aeration is an integral part to maintaining a healthy lawn. An aerator pulls plugs of grass and soil from your lawn, which over time slowly break down and work back into the turf canopy. There are three benefits to aerating your lawn on a yearly basis.
The first benefit is the reduction in compaction. Compaction can occur because of high traffic, heavy soil types (clay), and also poor irrigation management. Compaction makes it difficult for grass to develop roots and a healthy root system is the most important aspect in the survival of your turf. In addition to a reduction in compaction, you will also see a reduction in thatch. Thatch is simply a buildup of dead or decomposing material in your lawn. Some thatch is desired because it helps to protect the growing point of turf-grass, but too much thatch can severely inhibit air, water, and nutrient uptake.
Having easy access to air, nutrients, and water, reduced thatch and compaction the lawn will have a stronger and deeper root system. This is the most important benefit to aeration because it helps your lawn withstand a drought. A lawn with a poor root system will burn out much easier in the summer stress periods. A healthy lawn with a good root system will maintain its color longer into the summer. It will also compete less with weeds because the turf’s density.
