Which turf practice most improves drought tolerance?

Which turf practice most improves drought tolerance?

• A. Frequent light watering
• B. Deep, infrequent watering
• C. Watering at night only
• D. No irrigation

Answer: (B)

Deep, infrequent watering best builds drought tolerance because it encourages roots to grow deeper into the soil. When you water thoroughly but allow the surface to dry between applications, the turf develops a deeper root system that can access moisture buried farther down during dry spells. This makes the grass more resilient during drought and reduces reliance on surface moisture. Frequent light watering keeps moisture near the surface, so roots stay shallow. Shallow roots dry out quickly in hot, dry weather, making the turf more susceptible to drought stress. Watering at night can cut evaporation a bit, but it doesn’t promote deeper rooting and can increase leaf wetness and disease risk. No irrigation saves water but stresses the plant, diminishing its vigor and drought resilience rather than enhancing it.
