Which of the following is a listed benefit of taller mowing height?

• A. Increased clipping volume
• B. Higher water use
• C. Less weed competition
• D. More frequent mowing

Answer: (C)

Raising mowing height helps the lawn outcompete weeds by creating a thicker, taller canopy. When the grass leaves are allowed to grow longer, they shade the soil more effectively, limiting the light that weed seeds and young weeds need to germinate and establish. A healthier, denser turf then uses water and nutrients more efficiently, leaving fewer resources for weeds to exploit. That combination makes less weed competition the best outcome of a taller mowing height. The other options don’t reflect benefits of taller height: clipping volume isn’t inherently increased by taller cuts, and taller height doesn’t inherently require more frequent mowing or more water use; in practice it can reduce stress and even lessen mowing frequency and water loss.
