  • Read “Using Gray Water in the Landscape” by Kim D. Coder, Extension Forester, UGA.

  • Read “Best Management Practices for Landscape Water Conservation “

http://extension.uga.edu/publications/detail.cfm?number=C873

  • Water slowly and deeply.  Deep watering encourages root growth.
  • Use drip irrigation or soaker hoses.  They use 50% less water than sprinklers.
  • Check your irrigation system.  (1) Is the timer set correctly?  (2) Are all the nozzles working?  (3) Are all the nozzles the same type?  There is a significant variance in water applied between rotary sprinklers and spray heads.
  • Set a timer and/or use a rain gauge when watering the lawn or garden.
  • Check outdoor faucets, sprinklers and hoses for leaks.  Replace washers as required.
  • Select plants that are drought tolerant and have low water needs.  Group plants with similar water requirements in the same zone.  For a listing see

Check with your local water system to determine if they have more restrictive regulations.
