Your lawn needs less water than you think! A healthy lawn needs only 2.5 cm (1") of water per week. Watering deeply and less often promotes deeper root growth and your grass will become healthier and more drought resistant.
Tip #1: Step on your grass. If the blades spring back, wait to water.
Tip #2: To test how much you are watering your lawn, place a tuna can or a jar with a mark of 2.5 cm (1") on it and place it in a location that receives good sprinkler coverage. When the water is at the 2.5 cm (1") mark, turn off the water.
Longer grass provides more root shade, discourages weed growth, and retains more water. This makes your lawn healthier and more drought resistant.
Don't throw your grass clippings out, and practice "grass-recycling". Leave them on your lawn as mulch. This will save time, money, and water.
Tip #3: Look for leaks! Take some time every year to look for leaks in your sprinklers, unclog nozzles, replace broken sprinklers, and straighten up any leaning heads. Not for you? Call a professional, crack a cold one, and have them do the work for you. Fact: A 1.5mm hole that drips water for 3 months can waste 280,120 litres of water, or the equivalent of 927 filled bathtubs.
Irrigation Watering Tips
Avoid sprinklers that oscillate, produce mists or fine sprays to reduce the amount of water lost due to evaporation. Don't water on windy days as the water will just blow away and be more susceptible to evaporation.
Automatic irrigation systems often waste more water than a manual system. If you use an automatic irrigation system, it is encouraged that you check and adjust it once a month. By doing this, you can better follow the odd/even water restrictions.
Drip irrigation uses 30%-50% less water than regular watering methods. Drip irrigation lines are low to the ground or buried and drip directly on to soil and down into root sources. This reduces the amount of water that is lost to evaporation significantly.
