Drought stress is indicated by which signs?

• A. Higher rainfall
• B. Increased shoot length
• C. Wilting, footprints, color loss, and slowed growth
• D. Consistently lush turf

Answer: (C)

When turfgrass is under drought stress, you see several telltale signs because the plant is short on water and can’t maintain normal cell function. Wilting occurs as cells lose water and lose turgor, so the turf droops and looks limp. The footprints effect comes from that same loss of turgor—when you press on the leaf or turf, it doesn’t spring back as readily, leaving a visible imprint. Color loss happens because limited water slows photosynthesis and can lead to chlorophyll degradation, making the turf look pale or dull. Growth slows because essential processes like cell expansion and metabolism depend on adequate water, so new growth becomes stunted.

These signs contrast with conditions of ample moisture: higher rainfall reduces drought stress, consistently lush turf reflects good moisture, and increased shoot length usually indicates favorable growing conditions rather than stress.
