Tank grey and bore water options: Protect your investment – install an irrigation system!
To ensure the long term life of your lawn and to minimise the demands on your personal time to care for it, we recommend you install an automated irrigation system prior to laying your turf. We recommend you speak to an irrigation professional to explore all options before embarking on your turf project.
With continuing uncertainty of water restrictions in all areas, you may need to consider installing an independent water supply to ensure your turf and landscape can be sustained long term regardless of restriction bylaws enforced. Most homeowners are successfully establishing sustainable home lawns and gardens with tank, grey, and bore water.
The unique growth habit of all Coolabah drought tolerant turf varieties means they can live without any water for four months of the year. Pending seasonal weather conditions in northern Victoria, drought tolerant turf should only need to be watered between November and April, as compared to fescue lawn and other cool season varieties, which will usually require watering from September through May.
Once your drought tolerant turf has matured, don’t feel obligated to water every night. You should try to water less frequently, but with larger quantities. Eg. Deep watering once a week, instead of 10 minutes everyday. This will force the roots to chase the moisture further into the ground and help train your lawn to become more drought tolerant.
