Answer: Lawn aeration is the process of removing small cores of soil from the lawn.
Answer: Lawn aeration allows air, moisture, and nutrients to penetrate down into the root zone to help rebuild and revitalize your lawn. Aeration is ideal for lawns with high foot or pet traffic, hard compact soils, or excessive thatch buildup. Aeration is recognized by turf experts such as golf course superintendents as an important procedure to maintain vibrant lawns and to revitalize growth.
Answer: It is recommended that lawn aeration be done during active growth periods in the cooler tempratures of the spring or fall. Lawn aeration is ideal prior to fertilization or when reseeding areas of your lawn. The open holes help provide fertilizer and seeds greater penetration into the soil.
Answer: Nothing. The cores brought to the surface contain microorganisms, which help the breakdown of the woody thatch tissue layer just below the lawn’s crown. As the thatch layer is broken down, it is converted into organic matter that will then combine with existing soil particles. Also, as the cores begin to breakdown over a period of several weeks, the holes gradually fill in with a mixture of organic matter and soil, and the filled hole allows roots of existing grass plants to spread out and grow deeper, creating a healthier, thicker lawn.
