How does thatch contribute to a healthy turfgrass environment?

Thatch is a layer of organic matter that accumulates on the surface of the soil under the grass. Its role in balancing soil moisture is significant. Thatch can help retain moisture in the soil by slowing down water evaporation. This retention is essential for maintaining a healthy turfgrass environment, particularly during hot and dry weather conditions. When thatch is present, it can create a buffer that supports the grass roots and allows them to access moisture more consistently.

Additionally, while thatch has other benefits, such as providing habitat for beneficial organisms and contributing to soil structure, its most critical role in relation to the question is its ability to balance soil moisture levels. Thus, this characteristic is vital for sustaining turfgrass health, promoting growth, and preventing stress during periods of water scarcity.
