It is just as important how you water as how much you water. It is not that difficult to keep your lawn green and lush with a little planning when it comes to watering. You want to water deeply and infrequently to have a healthy deep rooted grass lawn . An oscillating lawn sprinkler can help you ensure that your whole lawn is evenly watered.
Let’s say you decide on 1 1/2 inches a week. You can do it in 2 doses or one, but don’t do just a little each day. If you do a little each day your grass will have shallow roots and you can have all kinds of drought problems.
If you have sandy soil in your garden, it is best to water your lawn twice a week since sandy soil drains faster and soon the water becomes too far down for your thirsty grass roots to reach it.
