What could be a negative consequence of having a significant thatch layer?

Having a significant thatch layer can lead to reduced grass root growth, which is crucial for the health and vitality of a lawn. Thatch is a layer of organic matter, primarily composed of dead grass stems and roots, that accumulates between the soil surface and the grass blades. When thatch builds up excessively, it can create a barrier that prevents water, nutrients, and air from penetrating the soil effectively.

As a result, the grass roots may struggle to access necessary resources, leading to stunted growth or even decline in the overall health of the grass. This reduced growth can manifest in various ways, including weaker plants that are more susceptible to pests and diseases. Therefore, managing thatch levels is vital to ensuring robust root systems, supporting turf health, and promoting a thriving lawn.
