Core Aeration – This process is designed to reduce soil compaction and make it easier for air, water and nutrients to reach the root zone. Core aeration assists in the development of a deep root system which leads to dense turf which is better able to cope with disease, drought and insect pressures. The removal of these 3 to 4 inch long cores of soil can be performed in either spring or fall and is arguably the #1 one way to keep your lawn in top shape.
