Optimum cutting height is determined by which characteristics of the turfgrass species?

• A. Color and texture
• B. Growth habit and Leaf Width
• C. Mowing frequency
• D. Root depth

Answer: (B)

Mowing height is determined by how the turfgrass grows and how wide its leaves are. Growth habit describes whether a grass forms upright clumps or a low, spreading canopy, which dictates how short you can safely cut without stressing or scalping the plant. Leaf width, or blade size, affects how much leaf tissue is removed with each cut; grasses with fine, narrow leaves can be mowed a bit closer because they still retain enough photosynthetic area after cutting, while those with broad leaves require a higher cut to avoid damaging the plant. Together, these traits set the practical height that maintains health, recovery, and a uniform appearance. Color or texture relate to appearance and cultivar, mowing frequency changes how often you cut but not the height itself, and root depth influences drought tolerance rather than the canopy height you should maintain.
