Aerating the lawn is a process that involves mechanically poking and pulling thousands of plugs from the ground. It is the naturally occurring process of air exchange between the soil and its surrounding atmosphere. It allows essential nutrients to better penetrate the root systems of the grass. It reduces soil compaction and thatch and helps in water absorption. It improves fertilization uptake and use while making the turf roots stronger and more tolerant to heat and drought. It definitely can help make your lawn healthier and more plush. Core Aeration is great to do in the spring and in the fall in the state of Iowa. Fall overseeding also works great with fall aeration. Precision Lawn Care recommends aerating twice a season at least on problem lawns. Please contact us for a free estimate.
