Which practice best supports drought tolerance in turf management?

• A. Frequent shallow watering
• B. Deep, infrequent watering
• C. Watering during peak sunlight
• D. Never water after 6am

Answer: (B)

Deep, infrequent watering promotes drought tolerance by encouraging turf roots to grow deeper into the soil. When water reaches deeper layers, roots extend downward in search of moisture, forming a more extensive root system that can access water during dry spells and support the plant through heat and stress. This deeper rooting also means water is used more efficiently, since the turf relies on stored soil moisture rather than constantly drawing from a shallow layer. In contrast, frequent shallow watering keeps most roots near the surface, so once surface moisture disappears, the grass quickly struggles. Watering during peak sunlight wastes water through rapid evaporation and can stress leaves, reducing overall turf health. Not watering after a certain early hour can leave the turf dry during hot periods, undermining resilience. The key idea is to water deeply enough to wet the root zone and do so less often, which builds drought tolerance in turf.
