its not hot yet
smaller amounts of water will evaporate in the morning
Smaller amounts of water evaporate in the cool morning.
The best time is in the early morning. If you water at night the grass could catch a fungus disease. If you water during the day some water gets evaporated so you have to use more water. Early morning is best.
It's called dew.
no, it will be more active in the morning but never completly stops absorbing
Grass is wet because of condensation. Vapors get converted into water droplets.
Watering plants and grass in the early morning conserves water because the plants absorb most of the water before the hot sun can evaporate it. I found that the best time to water is between 5am to 7am with a good one half to one hour soak one to two times a week depending on the heat. The roots grow deeper and therefore the grass grows thicker and chokes out the weeds. It works out better than watering a little every evening which can produce damaging results to your grass.
You should water Korean grass each day. Morning is the best time to do this. Your grass should get one inch of water per day during dry periods.
It is always better to water early in the morning before the sun is too hot.Watering in the evening can lead to root rot and fungus, etc. . .
Condensation
dew
condensation, where water vapor in the air cools and turns into liquid water droplets on cold surfaces like grass in the early morning.
