What role does deep, infrequent watering play in disease control?

Deep, infrequent watering plays a significant role in disease control primarily by helping to reduce the possibility of disease. This watering method allows the turfgrass roots to extend deeper into the soil, making them more resilient and better able to tolerate periods of drought and stress. Shallow watering tends to keep the upper layers of the soil consistently moist, which creates an environment that is conducive to fungal growth and other pathogens.

Additionally, deep watering encourages the development of a robust root system, which can improve the overall health and vigor of the turfgrass. Strong, healthy turf is less susceptible to diseases because it can outcompete pathogens for resources and better withstand the environmental stresses that can weaken its defenses. Overall, this practice supports a healthier lawn ecosystem, consequently reducing the chances of disease outbreaks.
