Soil compaction is a frequent cause of turf deterioration. Caused by lawn traffic such as walking and mowing, compaction is greatest in thetop 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 theatmosphere 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, suchas 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.
- Adequate amounts of vital turf nutrients including water, oxygen,nitrates, phosphorus, and potassium are unable to reach the roots.
- Aerators relieve soil compaction by removing evenly-spaced coresof turfup to 3″ in depth.
- Once the soil is aerated air exchange is improved and the soil caneasily absorb water,fertilizer and other nutrients.
- Aeration promotes deeper root growth for a lawn that is lush,healthy and drought resistant.
Achieving the Best Results
- Water area to be aerated the night before. This will help to soften the soil allowing for maximum core penetration.
- Before beginning, map out any obstructions such as sprinkler heads or drains.
- Cover every inch of the lawn and go over high traffic areas more than once.
- After aerating, water the lawn and apply fertilizer. This will promote growth and allow grass to compete with weeds as they grow.
