Saving water in the garden

The largest amount of water used in the home is actually used outdoors. There are four key things that you can do to save water in your garden:

Mulch to retain soil moisture. Mulching reduces up to 70% of water evaporation from soil.
Drip irrigation. These systems are much more efficient at delivering water where it is needed than spray systems. Existing spray systems can be converted to drip irrigation fairly easily.
Wetting agents and water storage products for your soil. Using water crystals will help to maintain soil moisture.
Plant drought tolerant species. Native plants require less water and fertilisers, plus they attract native birds and other fauna, making your garden a more pleasant place.

Water saving tips

Don’t water in the middle of the day, in windy conditions. or if it is likely to rain.
Make a small dam from mulch to avoid water running from soil.
Water the roots of plants rather than the leaves.
Cool season grasses should be mown longer in summer but warm season grasses, such as couch and buffalo can be kept shorter.
Avoid cutting grass by more than 1/3 of its length at any one time.
Reduce the amount of your yard that is grassed. Grass generally requires significantly more water than a well mulched garden with hardy plants. If you select your plants carefully you will also attract more native bird life.
Replace struggling plants in autumn with drought tolerant species.
Keep all your kitchen scraps, lawn clippings and garden waste for your compost bin.
To assist in the establishment of your new lawn and to minimise the amount of water it requires, it is recommended that you apply a light top dressing to your lawn.
Paths, patios and driveways must never be hosed. Use a broom, rake, outdoor blower or vacuum.
Pot plants use a lot more water than plants in the ground, so a review of your pots may help to reduce water usage.
Recycled greywater is an alternative source of water for the garden.
