The cessation of irrigation as temperatures cool is a critical component of autumn lawn care. Determining the precise moment to suspend watering is not arbitrary; it hinges upon a confluence of environmental factors, most notably soil moisture levels, precipitation forecasts, and prevailing temperatures. Discontinuing supplemental watering at the appropriate time promotes the overall health and resilience of turfgrass as it prepares for winter dormancy.
Halting irrigation at the optimal juncture avoids over-saturation of the soil, a condition that can foster fungal diseases and increase the risk of winterkill. Moreover, as grass growth naturally slows with decreasing daylight and cooler conditions, continued watering becomes redundant, wasting valuable resources. Observing these practices helps to conserve water while simultaneously strengthening the grass’s root system in preparation for the stresses of the dormant season.
