As summer time approaches, we need to ensure our gardens get a good drink of water while still being mindful of our water usage. Outdoor water use accounts for 25-50% of the average home’s water, with huge amounts of water wasted in the garden. With climate change making rainfall less predictable and in many instances lower than long-term averages, we need to be saving freshwater now more than ever.
You’ve probably heard this one before but it does make a difference! Temperatures are usually cooler in the morning and early evening, so watering during these hours allows the moisture to soak through the roots and keep your lawn hydrated throughout the day. Whereas, watering at night will keep your leaves wet which can allow fungi to grow and infect leaves – impacting your plant’s health.
Potted plants tend to dry out quickly without frequent watering. It’s important to water the base of your plant so that the water soaks through the soil as this encourages strong root development and will avoid fungal diseases from attacking your plants. Watering the base also means less water will be lost to evaporation, especially on hot, sunny days.
Mulch will help to retain soil moisture by reducing evaporation and restricting weed growth while improving the soil structure as it breaks down.
A range of plants are suited to the harsh and arid conditions where rainfall is sparse and unpredictable – these plants reinforce nature’s ability to adapt and flourish. Some examples include Banksia, Weeping Lilly Pilly, Birds Nest Fern, Callistemon Weeping Bottlebrush and many more.
Next time you wash your car, park it on the lawn so that the run-off water soaks into the grass. Also, use a bucket to wash down and rinse off your car to limit water use.
Slightly longer grass prevents your lawn from drying out, it also minimises evaporation from the soil underneath and forms shade, sheltering the roots from the sun.
Opt for an organic fertiliser over a chemical fertiliser as this requires less water after application and you only need to use small amounts. Spring and summer are also the best time to apply fertiliser as there is a higher chance of rainfall in these seasons - so get on top of it now!
There are many ways you can grow a healthy lawn and maintain your garden without wasting valuable water. By following a few of these tips you’ll notice a saving on your water bill and garden running costs, plus, water-efficient gardens often require less maintenance!
