Core aeration is the process of perforating the soil, as well as any thatch layer that might exist, removing a core or plug of soil and depositing that core on the surface to break down. Aerating will allow water, air and fertilizer to penetrate all the way down to the root zone. This in turn allows the roots to grow deeper, creating a healthier and thicker lawn. Many sports field and golf course managers will aerate up to 5 times a year, which proves you simply cannot put too many holes in your lawn. For residential yards we recommend at least one aeration each year.
Benefits of Aeration
Reduced Soil Compaction
Improved Rooting
Improved Water Penetration
Increased Absorption of Oxygen
Reduced Water Runoff & Puddling
Better resiliency and cushion
Overseeding typically follows aeration to fill in weak spots and ensure a healthy lawn. Seeds germinate more efficiently in the open spaces because of greater soil contact. Overseeding in itself aids in weed prevention because the new grass is able to crowd out potential weeds. Make sure to overseed immediately following lawn aeration in the fall to guarantee a lush and healthy lawn. Aerating and Overseeding cool season grass in the Springtime does not give the grass enough time to establish a strong root system before the strong heat of the summer which will ultimately cause the grass to thin out and be highly susceptible to weed invasion.
