Which of the following is NOT a characteristic of xeriscaping?

Xeriscaping is an approach to landscaping that focuses on reducing water consumption and conserving resources, especially in arid or semi-arid regions. The key characteristics of xeriscaping include the use of native and drought-tolerant plants, which are better adapted to survive with minimal water. This not only promotes biodiversity but also minimizes the need for supplemental watering.

Designing landscapes to minimize water usage is another essential element of xeriscaping. By planning the layout and selecting appropriate plants, these landscapes can efficiently use rainfall and irrigation, reducing overall water needs.

Incorporating efficient irrigation practices is also integral to xeriscaping. Techniques such as drip irrigation or rainwater harvesting help deliver water directly to the plants that need it, significantly decreasing waste and promoting water conservation.

The choice indicating the use of irrigation systems that waste water is not a characteristic of xeriscaping, as it contradicts the fundamental principles of conserving water and promoting sustainable landscape practices. Hence, this inefficiency is not aligned with the goals of xeriscaping, making it the correct response to the question.
