Do not water when the sun is shining
Then he is surprised that instead of the lush green there are only brown and bald spots on the ground. The motto here is: "Keep your hands off the tap when the sun is shining on you". Because the sun's rays make the water droplets act like a magnifying glass.
Best water in the morning
So you should only water the lawn when the sun is no longer shining. This means that you can water your lawn either in the morning or in the evening. Dew has accumulated overnight in the early morning, but this is not enough to keep the lawn sufficiently moist during the day.
That's why you should water your lawn in the morning. This is also much more efficient because in the evening the water does not evaporate as quickly and mold can form during the night. Also, watering in the evening does not fit into the natural course of nature. If you stick to it a bit, you will be able to enjoy a he althy lawn.
