Aeration is perfect during periods of rapid growth, which is usually when there is a lot of rain, such as in the spring and fall. Secondly, aeration stresses the turf, which can be harmful when the turf is already stressed from excessive heat and drought. We recommend fall aeration with overseeding at Capital Landscaping to loosen the soil and promote new growth at the same time. Finally, Aeration is beneficial to any lawn, but particularly those that have a lot of foot activity, are part of new development with compact soil, or, are part of a thatch management/prevention program.
