Aeration & Overseeding
Why aerate my lawn?
Lawn aeration is generally recognized as the best way to improve air/gas exchange and water/nutrient intake. Some aeration occurs naturally, but due to soil compaction or other soil conditions, lawns rarely thrive without some means of mechanical aeration.
In addition to compaction, thatch build-up (more than 1/2 inch) can be especially damaging to lawns. It acts as a barrier, preventing water and nutrients from getting into the soil.
Mechanical Aeration benefits your lawn in six ways:
- Reducing soil compacttion
- Penetrating heavy thatch
- Allowing more efficient watering and fertilizing
- Enhancing root growth
- Enriching surface soil
- Decreasing water run-off
Many years ago, crude aeration was accomplished by poking holes in the lawn with a pitchfork or other pronged device. Today, we have the advantage of mechanical aerators that actually remove small-diameter "plugs" from the soil.
The holes left in the turf allow moisture and nutrients to more easily reach the roots. As the soil naturally expands to fill the holes over a few weeks' time, the surrounding soil is allowed to loosen, reducing compaction.
The "plugs" are scattered on the surface and eventually break down to form a valuable top dressing that enriches soil near the surface and helps break down thatch.
