Watering Lawn

Question

What is the best time of day or night to water your lawn? My husband waters at night, but I think it’s better to water in the morning. Please settle this debate for us.

Answer 1

The best time of day to water is in the early morning, as less water evaporates when temperatures are cool and winds are calm. Late afternoon and evening watering also reduces evaporation losses if winds are calm, but tends to encourage fungal disease because the grass stays moist all night. Midday watering does not harm the lawn. However, more water is lost to evaporation.
