Lawns may deteriorate over time due to excess thatch, soil compaction, or a combination of the two. Aeration helps to manage thatch buildup and reduce problems arising from soil compaction. Proper aeration can help build a thicker, healthier turf with superior resistance to weeds, diseases, and insects. Most lawns will benefit from being aerated every 1-3 years with the frequency determined by the rate of thatch production and soil compaction. Compacted or thatchy sites will need more frequent aeration to correct the existing problem, up to twice a year for 1 or more years.
At Lakeland we offer Spring and/or Fall Core Aeration, but for various reasons Fall Core Aeration is always recommended. Although recently aerated lawns may look rough and in poor condition, if lawns are aerated when grass is actively growing (late spring or fall) lawns will quickly recover with proper mowing and regrowth. After aeration, allow the cores of soil to dry for 1-2 days, then mow over them to help break them up. The cores generally take several days to fall apart, depending on rain, mowing, and traffic on the turf. Aeration controls harmful thatch, increases root development, improves overall plant health, reduces soil problems, increases water retention (lower water bills).
