Many communities face water restrictions due to long-term droughts. One way to keep lush landscaping and save water is to promote "deep water" instead of frequent watering of plants. Deep water is when you fully saturate the ground for water-loving plants. You do this type of watering less frequently. Over time, the plants get enough water from deep watering, and they learn to send roots deeper into the ground to search for water, which helps to develop drought tolerance.
