How to Best water lawn
To make sure your plants get enough water, the general rule is to water your lawn about one inch every hour. While this rule of thumb may seem simple, many factors affect watering times, such as the type of soil and time of day. If you notice that your plants are looking drier than normal, try adding a little extra water. Depending on your soil type and climate, this can be an effective guide for daily watering.
One inch of rain is equivalent to 4.7 gallons of water per square yard, which is why you should use a large watering can. Watering cans that deliver water at a lower rate can lead to uneven distribution. To make your plants receive water from the sprinklers, be sure to place them evenly throughout the yard. If you’re trying to water multiple plants at once, you may want to set more than one catch-can to provide an even distribution of water.
