Coring is Important
Lawn aerification or coring is an important agronomic practice frequently done in the autumn. Coring punches holes into the ground to help alleviate compaction, and improve the quality of the turf.
Coring has the added benefit of helping to reduce the accumulation of thatch. Thatch is the layer of organic matter that develops between the green leaf tissue and the underlying soil. Excessive thatch layers are extremely detrimental to turf health. Thatch exposes the turf to a wide temperature fluctuation, has poor nutrient and moisture retention, enhances certain disease and insect pests, and decreases the success rate of overseeding lawns.
Coring helps reduce thatch accumulation by removing the organic matter. In addition, by working the soil form cores back into the lawn, the incorporated soil that is now in the thatch helps provide a more favorable environment for organisms that break down thatch. The benefits of coring increase with more core holes produced per given area (a function of tine diameter and tine spacing). With lawn coring/aerification equipment, multiple trips across the lawn will most likely be needed to generate a critical number of core holes
