Appropriate plant selection for water-wise shrub beds can help reduce water needs in the landscape. 

Shrubs can provide a more natural look, screen unsightly objects, create strong seasonal interest in the landscape, and provide a backdrop for showy perennials. Shrubs can also meet habitat and food requirements for a variety of wildlife species.

  • Look for native or species adapted to the local climate, soil type, and sun exposure
  • Choose flowering and fruiting shrubs for seasonal interest and food for wildlife, if desired
  • Mix evergreens and deciduous shrubs to create interesting texture combinations, seasonal interest (color, texture, form), and wildlife habitat
  • Combine different size shrubs for visual interest
  • Perform a soil test to assess soil conditions such as type, drainage, and fertility
  • Apply enough water during the first two years to ensure strong root establishment
  • Choose shrubs that require 2 or fewer irrigations per month
  • Group shrubs with similar water needs together
  • Group plants in a bed to create a more natural look. This will reduce maintenance, water use and lawn area
  • Use appropriate spacing based on mature plant size. Some overlap can help create a more natural look
  • For a more formal look, create bold, symmetrical patterns by spacing shrubs farther apart to showcase shrub bed shape
  • Many shrubs can be clipped or trimmed to create interesting geometric or 'neat' shapes
