What is a potential consequence of excessively high mowing height on turf health?

• A. Increased heat stress.
• B. Increased thatch buildup.
• C. Decreased disease risk in all cases.
• D. Eliminate pest pressure.

Answer: (B)

When you raise mowing height, the turf produces more leaf tissue and, if clippings aren’t removed or decompose slowly, that organic matter can accumulate near the surface and form a thicker thatch layer. Thatch sits between the soil and the living turf and can reduce water infiltration, air movement, and root health, ultimately stressing the turf. So, a potential consequence of excessively high mowing height is increased thatch buildup. The other options aren’t universal truths: simply taller grass doesn’t guarantee more heat stress, cannot guarantee lower disease risk in all cases, and won’t eliminate pest pressure.
