The process of aerating removes small cores of soil ranging in size from 1" to 3". After a few rains, these cores "melt back" into your lawn, mixing with any existing thatch. The holes made by aeration trap fertilizer and water. These growth pockets are where turf roots grow naturally and thicken. The oxygen and water can flow more freely through the root zone thanks to the relief of pressure caused by compacted soils.
Regular aeration can help avoid costly lawn renovations
The lawn's thatch acts like a roof. This layer of roots, stems, and other plant parts helps to shed water and prevent fertilizers and insect control from freely moving into the soil. A lawn that has too much thatch can require major renovations. Regular aeration aids in the natural decomposition of thatch by mixing soil cores with the thatch. Aeration
