Weeds are a primary result of poor turf quality.

• A. Sometimes
• B. Not sure
• C. True
• D. False

Answer: (C)

The main idea is how turf health influences weed pressure. A healthy, dense turf canopy acts like a living mulch, shading the soil and occupying space, light, and nutrients that weeds would otherwise use. When turf quality is poor—due to mowing too short, insufficient fertility, drought stress, soil compaction, drainage problems, or pest and disease pressure—the stand thins and bare patches appear. Those exposed areas are prime real estate for weed seeds to germinate and establish, so weeds become a major consequence of the weakened turf. While weeds can arise from other factors too, the strong link is that poor turf quality creates the conditions that favor weed invasion, so the statement is true.
