Is it OK to water your lawn at night?

Watering your lawn at night offers the main benefit of reduced evaporation; you conserve water while maximizing your turf’s absorption ability without the sun’s constant heat. Watering at night, however, can encourage disease in a poorly managed lawn. Although healthy turf may not have obvious disease issues from night-time watering, irrigation should occur during the morning to avoid possible grass damage over time. Whether it is best to water lawn in the morning or afternoon depends on the time of year.
