The most obvious advantage of choosing a lawn sprinkler system for watering is that you'll look like lush, healthy grass. Sprinklers keep your ground hydrated throughout the year. Automated sprinkler systems can make your watering schedule more efficient and effective. By setting your sprinklers to water your lawn at the right times of day and for the right amount of time, you can be sure that your lawn will be watered just enough without being wasteful. Remember that watering too little or too much can lead to dry grass, rotting grass, or disease.
