Installation

Important points for Sir Walter DNA Certified installation:
-
Install the grass as soon as possible after delivery
-
Lay on a bed of 100mm of quality turf underlay
-
Use Lawn Solutions Australia Lawn Launcher at label rates to give the grass a head start and retain moisture in the new soil bed
-
Roll to compact new turf to improve contact with the soil
-
Soak the newly laid turf thoroughly for 10-14 days after installation or until established
-
Reduce irrigation once established and water only when the grass appears to be dry
-
Minimise irrigation in the cooler months to avoid your lawn getting waterlogged
Irrigation
Sir Walter DNA Certified is a drought tolerant lawn that has stood the test of time in harsh Aussie conditions for over 20 years, however it is important to be mindful of correct and efficient irrigation practices to maintain a healthy lawn.
Important points for irrigation of Sir Walter DNA Certified:
-
If watering is necessary once established, water only when there are signs of the grass drying out, e.g. wilted leaves
-
Do not water in the cooler winter months unless there are signs of the above
-
If irrigation is needed, deeply soak the top 100mm of soil (generally
-
30 minutes with a standard sprinkler
-
will suffice)
-
Water early morning for improved efficiency and plant health
Mowing
Sir Walter DNA Certified can be mowed between 20 and 60mm. It is best mown with a rotary mower, but a cylinder mower can also produce fantastic results. Removing clippings is encouraged, however mulch mowing is fine as long as clippings are not thick enough to inhibit the lawn getting sunlight. Over winter it is recommended to leave your lawn slightly longer.
Important points for mowing Sir Walter DNA Certified:
-
Ensure that mower blades are sharp to prevent tearing of the leaf
-
Never remove more than 1/3 of the leaf blade at any one time unless dethatching
-
Dethatch if required in late spring for best results
-
It is recommended to remove clippings each mow to prevent thatch build up
Fertilising
Sir Walter DNA Certified is a low maintenance lawn that is easy to manage. If you do want it to remain healthy and have a nice, deep green colour, it is best to fertilise a few times per year.
Important points for fertilising Sir Walter DNA Certified:
-
Apply Lawn Solutions Australia fertiliser at a rate of 20-25g/m2 or 2-2.5kg/100m2
-
For best results, fertilise at least 3 times per year. Important dates are late spring, mid to late summer and late autumn
-
Always irrigate after applying fertiliser
-
On new lawns, apply fertiliser after you have cut your lawn at least once
-
To best maintain year-round colour, fertilise in late autumn and apply Colourguard PLUS at 10 to 12 week intervals until spring
Weed & Pest Control
Sir Walter DNA Certified has a fantastic natural resistance to most pests and weeds. To keep weeds at bay, it is important to fertilise your lawn regularly to keep it healthy. This will ensure it is sufficiently dense to block weeds out, and high nitrogen levels will also keep most weeds away. To ensure your lawn remains pest free, always keep an eye out for signs of infestation and be proactive with preventative pesticides, such as Acelepryn GR.
Most commercially available chemical weed and pest control products can be used on Sir Walter DNA Certified (with the exception of Weed ‘n’ Feed), but it is always best to read the label and check with your Lawn Solutions Australia grower for recommended products before any application.
