Aerating
Soil compaction is a frequent cause of turf deterioration. Caused by lawn traffic, such as walking and mowing, compaction is greatest in the top 2-3” of the soil. In compacted soil, dirt particles are forced together, reducing the area where roots can grow. Aeration, the process of mechanically removing cores of turf, relieves compacted soil by improving the exchange of water and critical nutrients between the atmosphere and the grass’ roots.
For optimal effectiveness, aeration should be performed at least once annually. Spring (between March and May) and/or fall (between August and November) are the ideal times to aerate cool-season grasses, such as perennial ryegrass and Kentucky bluegrass. Warm-season grasses, such as zoysiagrass and bermudagrass benefit the most from spring and summer aeration. In drier climates, aeration increases drought resistance while decreasing the amount of watering necessary to help lawns remain healthy.
Lawns that receive regular aeration will be greener, easier to maintain and suffer from fewer pest problems and disease.
