What is the first sign of drought on a grass lawn?

• A. Grass blades wilt
• B. Leaves turn brown all over
• C. Grass blades grow taller
• D. Soil moisture increases

Answer: (A)

When a lawn starts to experience a lack of water, the first thing you’ll notice is the grass blades becoming limp and wilted. This happens because plants lose water and pressure inside their cells, so the blades can’t stay upright or firm. It’s the earliest visible sign that the grass isn’t getting enough moisture, even before any color change occurs. If drought continues, you might later see brown patches from tissue death, and other options don’t fit because they describe conditions opposite to drought (soil moisture would be low, not increasing) or plant responses that aren’t immediate, like blades growing taller. So the initial signal is wilting of the grass blades.
