To what does thatch contribute?

• A. Disease and insect problems
• B. Increased soil fertility
• C. Improved water retention
• D. Faster growth

Answer: (A)

Thatch creates a living-to-dead organic layer that sits between the soil and the green turf, forming a moist, shaded microhabitat. This environment favors pathogens and turf pests, increasing the risk of disease and insect problems. At the same time, the thick thatch layer reduces air movement and slows water and nutrient movement into the root zone, stressing the turf. Thatch does not add meaningful soil fertility, and it usually isn’t beneficial for water retention or growth; in fact, it can hinder both. So the contribution most associated with thatch is disease and insect problems.
