Basic Lawn Watering Principles.
Morning watering is infinitely better than evening time. Wet grass overnight can encourage myriad types of diseases. Watering during the heat of the day may actually cook the lawn and can also be counterproductive in that the water is lost to more rapid evaporation.
Water the lawn at a rate of about one half inch of water per hour. If you water the grass too rapidly you will cause runoff which wastes your time and your money
You can test the rate of flow for a specific sprinkler by putting smaller cans in easy reach of the sprinkler and then measuring the water level about every 15 minutes.
The most effective way for you to water your lawn will be drip irrigation or by soaker hoses with a timer attacked to allow your system to water in the morning when it is most effective.
When you water very frequently and water lightly, it promotes very shallow rooting according to Virginia Agriculture. It will also make the plants less hardy and make them suffer more during a dry season. Conversely if you water too much then damage may be just as pronounced as not watering enough.
There is no substitute for water when the season ius very dry however make sure that you’re watering wisely and that you are adhering to your local water regulations or restrictions that may be in place.
