The Aerator permeates the soil with small holes which allows air, water and nutrients to pass through more easily to the grass roots. This is beneficial as this helps the roots grow more deeply, meaning a healthier, thicker and more luscious lawn.
The machine also removes soil compaction and helps water move into the soil profile. Soil that is compacted has too many solid particles, which can prevent the soil absorbing what it needs to flourish. Aerating your lawn stops the roots from being starved as there is nothing blocking that process.
If your lawn dries out easily then it could be crying out for aeration. If you remove a small slice of your lawn about 4 inches deep, and there’s a layer of thatch taller than half an inch, it’s time to give it some breathing space.
