A grass plant spends most of its life putting on growth - above and below ground. Not all of this leaf and root growth develops properly, much of it turns into a thick mat at soil level. We call this ‘thatch’.
Thatch suffocates the soil, it acts as a sponge for surface water, stopping it reaching the rootzone and keeping the leaves damp for longer - leading to disease. Thatch also inhibits the flow of air, warmth and nutrients – leading to unhealthy grass. Thatch therefore needs to be removed at regular intervals. We do this with a scarifier – a petrol-powered machine which rips out thatch and other loose or dead material (including moss).
