What is the maximum recommended thickness for a thatch layer?

The maximum recommended thickness for a thatch layer is typically 1/2 inch. Thatch is a layer of organic material that forms from dead grasses and roots on the soil surface. When the thatch layer is too thick, it can inhibit water and nutrient absorption into the soil, leading to poorer turf health and increased vulnerability to pests and diseases. A thatch layer of around 1/2 inch is considered optimal because it allows for a healthy ecosystem in the soil while preventing the negative effects associated with excessive thatch accumulation. By maintaining this thickness, turf managers can promote healthier grass growth and minimize maintenance issues.
