The most obvious benefit of utilizing xeriscaping in your landscaping design is the reduction of water use.  There are many other direct and indirect benefits.

Many homeowners will see a 50% reduction in water consumption for landscape maintenance.

There are many not-so-obvious benefits too.

Xeriscape gardens typically have much lower maintenance requirements.  This means fewer leaves to clean up and lower weeds maintenance.  Minimal lawn mowing work.

If your area enacts water restrictions during times of draught, your landscape will be well prepared to continue to thrive within those watering restrictions.  When traditional yards are turning brown and dying, your garden will continue to thrive.
