Thatch is what we call decaying leaves and roots that form a layer restricting air, light, and water from penetrating the soil. 

Regular dethatching, especially during Spring & Autumn, is great for your lawn and will help our products perform at their best.

Dethatching, or scarifying as it is also known is more important for some grasses (fine fescue, browntop) than others (rye, tall fescue) as it removes unwanted organic matter, including moss and it provides a great opportunity to oversow your lawn with fresh grass.
