Proper mowing practices help turfgrasses compete for what resource(s)?

• A. Water
• B. Nutrients
• C. Sunlight
• D. Space

Answer: (C)

Proper mowing regulates the turf canopy to maximize light capture, which is how turfgrass competes for energy. A dense, evenly mowed stand intercepts more sunlight, supporting photosynthesis and keeping weeds from getting light. If mowing is too low or uneven, the canopy thins or gaps form, letting weed seedlings reach light and weakening the turf’s competitive edge. Water and nutrients are essential resources, but mowing doesn’t directly supply or remove them; space relates to how densely the stand grows, which mowing can influence indirectly, whereas the primary competition addressed by mowing practices is light.
