What method can help in effective water conservation?

Utilizing mulch in landscaping is an effective method for water conservation because it helps retain soil moisture, reduces evaporation, and minimizes the need for frequent watering. Mulch acts as a barrier between the soil and the elements, shielding the soil from direct sunlight and heat, which can dry it out. Additionally, it prevents weed growth, which competes with plants for both water and nutrients. This means that with correctly applied mulch, plants can thrive with less water, ultimately leading to a more sustainable approach to landscaping. By enhancing soil structure and health, mulch supports both water retention and efficient water use in gardens and landscapes.

In contrast, increasing lawn size typically leads to the need for more water, while installing automatic sprinklers can lead to overwatering if not managed properly. Flood irrigation, on the other hand, is often less efficient and can result in significant water loss through runoff and evaporation, making it a less suitable option for conservation.
