Aeration and dethatching are important treatments for the health of your lawn. Aeration consists of coring the soil, which has the effect of reducing the compaction of your land.
This will facilitate the penetration of nutrients and water.
Dethatching, on the other hand, removes the thatch. Thatch is a layer of organic matter that forms over time at ground level around blades of grass. This layer can smother the grass, obstruct the drainage of the ground and facilitate the procreation of insects and fungi which can affect the health of your lawn.
