What is a key benefit of sustainable landscaping practices?

Sustainable landscaping practices primarily focus on the efficient use of resources in a way that benefits the environment. One of the key benefits is the conservation of water. Sustainable landscaping often incorporates methods such as xeriscaping, which uses drought-resistant plants, and employs efficient irrigation techniques that minimize water waste. By choosing native plants and designing landscapes that require less water, sustainable practices contribute significantly to water conservation efforts. This approach not only helps in maintaining water resources but also reduces the demand for artificial irrigation, ultimately leading to lower water costs and making landscapes more resilient to climate variability.

The options that suggest improved aesthetic appeal, increased fertilizer requirements, and higher maintenance costs do not align with the principles of sustainable landscaping. While aesthetics can be improved, it's not the central focus of sustainability; similarly, sustainable practices aim to reduce fertilizer use and maintenance costs by fostering a more self-sufficient ecosystem.
