3.5.4 Xeriscape Irrigation Design Principles

  • Plan the irrigation system design at the same time as the planting and landscape design.
  • To minimize water waste, group together plants with similar light and water requirements, and place them in an area that matches these requirements. Separate irrigation zones according to the specific watering needs of the various species of plant materials in the design.
  • Use drip and/or bubbler systems for trees, shrubs, perennials, and groundcovers.
  • Water deeply and infrequently to develop deep roots. Avoid watering between 10 am and 6 pm to reduce water loss through evaporation.
  • Adjust irrigation controllers to accommodate changing weather/seasonal conditions. Install a rain sensor to shut off controllers when it rains.
