Lawns may deteriorate over time due to excess thatch, soil compaction, or a combination of the two. Aeration helps to manage thatch buildup and reduce problems arising from soil compaction. Proper aeration can help build a thicker, healthier turf with superior resistance to weeds, diseases, and insect pests. View the UW Extension publication below that discusses when and how to aerate as well tip for topdressing and rolling.
