Improves turf health. One of the best benefits of lawn aeration is that it can improve the overall health of your grass. Core aeration works to provide the root zone with greater access to air, water, and fertilizer. This access to air, water, and nutrients improves the health of the turf, resulting in deeper and more extensive turfgrass roots.
Reduces thatch build-up. If thatch, the layer of dead grass that accumulates on your lawn, builds up to a thick layer, it can rob your grass of necessary rain and nutrients. Core aeration helps manage that build-up by introducing thatch-decomposing microorganisms from the soil to the top of the thatch layer.
Relieves soil compaction. Compacted soil can prevent air, water, and fertilizer from reaching your lawn’s root system, causing dead spots, patches and/or thinning. By removing cores in the aeration process, soil density is decreased, thus relieving compaction.
Reduced water runoff and puddling. If you find your yard has runoff or puddling problems after a rain, aeration could be the fix you need.
Prepares grass for winter dormancy and a green spring. Before your cool-season grass goes dormant, make sure it’s in tip-top shape by pairing fall aeration with fall fertilization. Aerating prior to fertilizing will help the nutrients soak in more effectively. And planning for aeration and fertilization in the fall gives cool-season grasses enough of a buffer to protect the grass from summer drought stress and ideally enough time before the first winter frost arrives.
