Aeration (Core Plug Aeration)

Core plug aeration removes plugs (consisting of both soil and thatch) from the lawn and creates holes in the soil. The plugs are left on the surface of the lawn as they have micro organisms and nutrients in them that nourish the lawn. Over time, usually 2-3 weeks, the plugs will decompose and fade away. The net result of having aerated a lawn is that the root system has more access to air, water and nutrients. In addition, aeration helps to soften up compacted soil which will allow the soil to take in more water, allow the lawn to grow deeper and healthier roots and this will in turn help the lawn to with stand dry periods and hot temperature.

Soil compaction is the root cause of the need for core plug aeration. It occurs over time from traffic on the lawn (walking, playing, pets, mowing- particularly in the same pattern where the tires touch the turf). In addition, rain itself and watering mechanisms such as lawn sprinklers can help to increase soil compaction by compacting soil and eliminating/reducing air pockets where the root system of the lawn may grow. Core plug aeration ultimately results in an improvement in depth for the root system which can also result in natural breakdown of thatch- another contributor to soil compaction.

What are the benefits of core plug aeration?
1) Lawn doesn’t need to be watered as often as the root system is more open to receive water.
2) There is less of a runoff affect from water and water pooling is often eliminated or reduced.
3) Increased ability for the lawn to take in water, fertilizers, nitrogen and oxygen.
4) Increased heat and drought tolerance.
5) Improved rooting.
6) Increased, natural thatch breakdown.
