Which of the following practices is crucial for achieving water efficiency in landscaping?

Choosing species that suit local climates is crucial for achieving water efficiency in landscaping because it promotes the growth of plants that are naturally adapted to the local environment. Native and drought-resistant plants typically require less water, fertilizer, and maintenance, leading to substantial water savings. By selecting plants that thrive in the local climate, the need for supplemental irrigation is minimized, thereby enhancing water conservation efforts.

Additionally, incorporating climate-appropriate species can improve the resilience of landscapes to pests and diseases, reducing the reliance on chemical treatments and further conserving water and resources. This practice supports the overarching goals of sustainable landscaping by fostering ecosystems that can flourish with minimal human intervention, ultimately contributing to a more sustainable water management system.
