Is it OK to water grass in the evening?
Beside this, is it bad to water grass at night?
And watering in the morning keeps the turf cooler during the hot parts of the day, which means less stress on the grass. "A wet lawn at night is the perfect condition for fungus to grow." Along with cutting the lawn too short, watering a lawn at night is about the worst thing you can do to it, he says.
Also question is, is it better to water in the morning or in the evening?
Watering your plants at midday is inefficient because the sun and heat cause the water to evaporate before the plants can absorb it. Watering in the morning is best, but it's not always convenient. While watering plants in the evening is not ideal, you may need to do it occasionally.
The best time to water your lawn is from 4-6 am. This is the best time to water your lawn in Texas or other warm climate locations because the sun is not as high as it is later on in the day. During that time, the heat of the day can evaporate 30-50% of your water.
