What is the best time of day to water my lawn?

Last Updated: January 07, 2008

The best time of day to water a lawn is when solar radiation, temperature, and wind are minimal and humidity is high. This reduces the amount of water lost to evaporation and maximizes the water that penetrates the soil. Since prolonged leaf wetness may promote some diseases, late evening should not be the normal watering time. To facilitate the removal of dew and get maximum water efficiency, the best time to water is early in the morning.
