Water Tips

Lawn Care for Conservation
If you find that your lawn dries out quickly and needs more frequent watering than other lawns in your suburb, there are ways to minimise waterings.


  • For cool season grasses winter is the time to drop your mower down to about 2.5cm (1") and this will let the light and warmth into the thatch.
  • Remove weeds regularly from garden beds because weeds compete with other plants for water.
  • Aerate your lawn yearly. It prevents soil compaction and greatly reduces run-off from the lawn.
  • Improving your soil can also help reduce your watering needs. Try topdressing your soil with organic material. Organic material helps your soil hold water longer.
  • Keep chemicals off your lawn. Organic lawns require less watering than chemically-treated lawns.
  • Allow your lawn to temporarily brown out, or go dormant, when drought conditions persist. Usually this will not hurt a healthy, established lawn because the roots continue to live and are ready to send forth new shoots when conditions improve. There may be times during the year when it's just not worth trying to keep your lawn green. Note: You should continue to water lawns less than a year old through dry spells.

Landscaping for Conservation
Your landscape design also can impact water waste.


  • Narrow strips of lawn less than 10 feet by 10 feet, grass in curving areas, and grass on slopes are difficult to water efficiently. A possible solution is to remove turf from the edges of slopes and replace it with shrubs or groundcover to buffer run-off.
  • Using plants that are native to your area, you will contribute to local biodiversity and reduce need/costs for fertiliser, pest control and replacement plants.
  • Apply the principles of hydrozoning to plant selection and arrangement - Primary (3 drops) high water use plants; Secondary (2 drops); moderate water use plants; Elemental (1 drop); low water use plants.

Hydrozoning
Apply the principles of hydrozoning to plant selection and arrangement:
  • A broad selection of plants may be used, but keep high water-demand plants to a minimum.
  • Arrange plants having similar water requirements together (hydrozoning) and take this into account when deciding soil improvement and mulching, and when managing irrigation.
Some leading nurseries label their plants with drop icons signifying the appropriate hydrozone, described in three categories:
  • Primary (3 drops) high water use plants.
  • Secondary (2 drops); moderate water use plants.
  • Elemental (1 drop); low water use plants.

Drip Watering System
Drip irrigation is the best way to water the plants at ground level where they need it the most. It was initially developed for the agricultural industry but it is now extremely popular in Australian residential gardens, due to their water efficiency.
Advantages of a Drip Irrigation System:
  • minimised fertiliser or nutrient loss due to localised application of water
  • highly efficient water distribution
  • allows recycled water to be used safely
  • maintains water within the plant’s root zone where it is most needed
  • reduces soil erosion
  • supply can be regulated by controlling the output of valves and nozzles 
  • piping is easily laid and suitable for most environments
  • great for windy areas
  • suits all types of soil and plants
  • reduces the risk of plant fungal and insect problems
  • loses the least amount of water from wind, evaporation and run off
  • doesn’t waste water on weeds

How to Water Trees
  • Cut grass back from the trunks of trees. Watering the trunks wastes water and promotes rot on the tree trunk.
  • Create catch basins around trees, especially those on slopes. This minimises runoff and allows water the time needed get down in to the roots.
  • The majority of trees fine water absorbing roots are located in the top 10 to 30cm of soil. Checking soil moisture in the tree's root zone is the most appropriate means of determining soil moisture. If the soil is moist at this depth, water is not needed.
