Lawn aeration is a process used to combat lawn compaction. Compaction of lawn can cause puddling, erosion, water runoff, and lawn diseases. By perforating the lawn, aeration makes it easier for oxygen, nutrients and water to reach the grass roots. A lawn laid from sod is more likely to need aeration, as is one that receives heavy foot traffic. Aeration has numerous benefits, such as increased root growth, reduced runoff, and improved control of weeds. There are four methods of aeration: core, spike, blade and liquid. Lawn aeration is often performed annually, but could be done more or less often. In cold weather regions, fall is the best time to aerate.
- Soil becomes compacted due to daily foot traffic, weather and construction.
- Lawn aeration reduces runoff and erosion, controls weeds, and encourages root growth.
- There are are several methods of aerating a lawn: core, spike, liquid and blade (or slice).
“Aeration alleviates soil compaction, prevents excessive thatch buildup, and loosens soil so that roots can dig deeper and grow more densely.”
