Employing drought-resistant plants is the most efficient water use reduction strategy for landscaping because these plants are specifically adapted to thrive in environments with limited water availability. They possess characteristics that allow them to conserve water, such as deep root systems, thicker leaves, or a waxy coating that minimizes transpiration. By selecting drought-resistant plants, the need for supplemental irrigation decreases significantly, especially in arid climates or during dry seasons. This not only contributes to lower water consumption but also promotes sustainable landscaping practices that are better suited to the local climate and ecological conditions.

Using traditional non-native plants may not be efficient in reducing water use, as these plants often require more water to establish and thrive in a non-native environment. Installing an automatic irrigation system can lead to potential water overuse if not managed properly, as it might not account for local climate variations or the specific needs of the plants, which could lead to wastage. Similarly, choosing high-water demand species inherently contradicts the goal of water conservation, as these plants require more irrigation and maintenance, thus increasing overall water consumption.
