In a nutshell, xeriscaping is water-efficient landscaping that’s appropriate to the natural environment. In New Mexico, xeriscaping means using plantsthat don’t require much water.

This will allow the water to soak deeply to the plant’s roots.

For trees and large shrubs, you may need to move emitters outwardand add extra emitters as plants grow so the water soaks the entire root zone. 3. BACKFLOW PREVENTER/ ANTI-SIPHON VALVE Keeps irrigation system water from being siphoned back into your drinking water. Backflow preventers are required by city ordinances. 4. MULTI-EMITTER HYDRANT Delivers water from a single riser pipe to multiple locations. Each outlet’s flow rate can be individual- ly controlled by using emitters that deliver different amounts of water. 5. MICRO-TUBING Delivers the water from a multi- emitter hydrant to the location of individual plants. 10. MAINTAIN YOUR XERISCAPE 10
