The most efficient way to water the lawn during the summer is to do so in the morning at least three times a week with a pulsating sprinkler if necessary. A lawn should be watered with the proper amount of water to ensure root growth.
It's best to water the lawn during the morning in the summer since it's cooler and there isn't as much wind to scatter the droplets. In the middle of the day, when the sun is higher in the sky, the water droplets can evaporate before they soak into the soil. Water can cling to grass when the lawn is watered during the evening, which can lead to the growth of fungus. Any time between 4:00 to 10:00 a.m. is the best time to water the lawn in the summer.
A lawn should be watered at least three times a week during the summer season in order for the roots of the grass to grow deep into the soil. By watering a lawn too much, there's a chance that a fungus could start to grow. Frequent watering also leads to a shallow root system, since the roots have become used to being watered often, which means they may not grow deeper in search of water.
