What could indicate drought stress in turfgrass?

Drought stress in turfgrass can be indicated by dry soil below the surface because it directly affects the plant's ability to absorb water. When the soil lacks moisture, the roots cannot access the necessary water for the grass to thrive, leading to signs of stress such as wilting, browning, or even death of the turf. Monitoring the soil moisture at various depths is crucial for assessing the water availability to the grass roots, especially in periods of limited rainfall or high temperature.

While a white cast on leaves could suggest various issues, such as disease or nutrient deficiencies, it is not a definitive sign of drought stress. Excessive thatch can contribute to various problems in turf health but does not specifically indicate drought stress as it relates more to water retention and root health. Irregular patches of dead turf could stem from various factors, including pests or diseases, not just a lack of water. Dry soil below the surface, however, is a clear and direct indicator of insufficient water supply, making it an essential aspect to monitor in turfgrass management during drought conditions.
