Drought is spread across the country in many areas, with the antagonising wait for rain growing each and every day. Local councils continue to increase water restriction levels, with many of these water restrictions impacting on home-owners ability to water their lawns.
Always check the relevant water restrictions in your area as these vary greatly around the country. Your water supplier will have all the necessary information on their website. Also, your local turf supplier should have helpful advice on the local conditions and ways to use and save water.
There are exemptions available for new lawns in some areas even in level 2 restrictions, so people shouldn’t be deterred when looking to install a new lawn as they can still easily install and establish during this time.
Freshly laid turf needs to be watered a couple of times a day, every day, for the first couple of weeks. Once your lawn sets root into the soil, it is starting to become established. You can test for this by trying to gently lift a corner of a roll or slab, if it doesn’t lift easily, the roots have set into the soil. This is a good thing as it means your lawn is growing well.
Once establishment is happening you can start to back off the watering, depending on the weather and the climate in your region.
Level 2 water restrictions will be in place for everyone in Sydney, the Blue Mountains and the Illawarra as of the 10th of December.
You can water new turf using:
A hand-held hose fitted with a trigger nozzle for up to four weeks from the delivery date, following the watering plan below. This applies to areas of any size sprinklers and watering systems for up to four weeks from the delivery date, following the watering plan below. This only applies if you have a continuous area of new turf larger than 30m2.
Make sure you keep your receipt and any other order confirmation documentation as your proof of purchase.
Drought-proofing your lawn starts with establishment. New lawns will require regular watering during the establishment phase and the importance of allowing a concession for this time is paramount. These allowances save water in the long run. A well-watered newly installed lawn will develop deeper roots, providing far better drought tolerance in the future. What you use now, rather than a splash and dash method of watering, will save you hundreds of kilolitres in the future and can even diminish the necessity to water your lawn at all.
You will need to keep your new lawn moist at all times. Watering 4 times a day in warm conditions is quite normal. An example schedule would be:
You don’t need to flood your lawn, just be sure to keep the turf and immediate underlying soil moist. You must be systemic, ensuring you water all areas. Keep in mind that during hot conditions, especially if it is windy, the lawn will dry out very quickly and additional watering may be required. Your lawn will let you know if it is drying out by its appearance and behaviour. The leaf blades will start to curl, shrivel and dry out so you’ll know when it needs a drink.
The best way to water is by overhead irrigation, in fact to establish a new lawn, overhead watering is the only way to go. Portable sprinklers attached to the end of a hose are cheap and efficient. Just move them around the lawn as required. A tap timer will ensure you don’t leave the water on for too long and wastewater. An in-ground, pop-up irrigation system takes this a step further. This can be connected by a manual tap timer, or a computer-controlled timer that is programmed to run as required. Hooking up a pop-up system to a rainwater tank or using recycled water is the most environmentally friendly and cost-effective method.
Grey water is the wastewater from washing machines, laundry tubs, baths, showers and wash basins. It does NOT include wastewater from the toilet, dishwasher or kitchen sink, as these can contain unwanted solids and potentially nasties. Grey water can be used on the garden and lawn by bucket or water re-use system. This is a good way to recycle your grey water, reduce pressure on grey water waste systems, save on valuable drinking water reserves as well as save money. If you want to use grey water be sure to use environmentally friendly, sustainable detergents that won’t harm your lawn. Before using grey water, it is best to check with your local Council for advice as there may be regulations regarding the use of grey water in your area.
If you live in sand belts such as Perth underground water can be tapped into a bore or a spear. Contact your local Council to see if underground water is available in your area.
Once your lawn sets root into the soil, it is starting to become established. You can test for this by trying to gently lift a corner of a roll or slab, if it doesn’t lift easily, the roots have set into the soil. This is a good thing as it means your lawn is growing well. Once establishment is happening you can start to back off the watering depending on the weather and the climate in your region. The idea is to get to a point where you water less frequently but give the lawn a deep soaking when watering does occur.
This encourages deep root systems and ultimately a more self-sufficient and drought tolerant lawn. As the water drains through the soil, the roots seek the water out deeper in the soil rather than just hanging around near the surface, which is what will happen if you just give short, regular watering. Educate your lawn to go the distance.
Drought tolerance is one of the key characteristics of buffalo lawn, like Sir Walter. In many areas that receive fairly regular rain, you will almost never have to water a drought tolerant lawn at all, except during routine maintenance tasks like fertilising when you have to water the fertiliser in. During extended dry periods you may have to water your lawn more regularly to maintain a lush green look, but this is purely for cosmetic reasons.
The best time to water your garden is early morning or late in the afternoon/early evening, when there is no wind and less chance of water loss due to heat related evaporation. In humid areas, avoid late afternoon or early evening watering as this can increase the chance of fungal diseases. In these areas early morning is best.
Lawn Solutions R&D programs have a strong focus on bringing lawn to Australian consumers that not only look great but use much less water than older varieties and once established will need little to no water to stay alive.
New turf varieties such as TifTuf Hybrid Bermuda (couch), have been selected and released to the market because of it’s superior drought tolerance.
