What does excessive thatch buildup lead to?

Excessive thatch buildup leads to decreased air flow to the soil, which is crucial for maintaining healthy turfgrass. Thatch is a layer of organic matter consisting of dead grass, roots, and other debris that accumulates on the soil surface. When thatch becomes too thick, it can inhibit the movement of air, water, and nutrients into the soil, which negatively impacts plant health.

Reduced air flow can lead to several problems for the grass, including poor root development, increased susceptibility to diseases, and difficulty in accessing soil moisture and nutrients. In a well-maintained turf environment, adequate air circulation is essential for promoting healthy growth and preventing issues associated with moisture retention and pathogen development. Thus, managing thatch levels is vital for ensuring the overall vigor and sustainability of the grass.
