This document provides a step-by-step guide to converting an existing landscape into a water-wise xeriscape over the course of three years. It discusses zoning high, moderate, and low water use plants. Converting an irrigation system and installing drought tolerant plants in stages is recommended. Xeriscaping saves water while creating an attractive landscape using native and adapted plants suited to New Mexico's climate.
