Aeration has many benefits—it will help control thatch, improve soil structure, thicken underground roots and rhizomes, relieve compaction, and improve penetration of both water and fertilizers.

The aeration process removes small cores of soil and turf from your lawn. These cores are left on the lawn to break down and melt back into the soil after a mowing and/or rainfall. These cores are a source of organic matter for your lawn. Organic matter contributes to improved soil structure, a major factor in turfgrass growth and development.

Fall is an excellent time to aerate the lawn. Ideally, lawns should be aerated annually.
