Sir Walter DNA Certified

Sir Walter DNA Certified is a soft leaf buffalo, born and bred on our Maitland Farm in the Hunter Valley for Australian conditions. Since its introduction in 1997 over 50 million metres have been sold Australia-wide, from the cool tablelands, to the dry west and the tropical north. No other lawn turf combines such a comprehensive range of attributes into one easy-to-care-for variety.
For over 25 years it has stood the test of time, in full sun or light shade, in extreme heat, frost and drought. Grown under strict conditions and guidelines, our Sir Walter DNA Certified buffalo is AusGAP assured quality.

Sir Walter DNA Certified Buffalo features superior colour retention and fungus resistance compared to other varieties that are commercially available, as well as being less invasive into gardens than Kikuyu and Couch and less mowing than Kikuyu (approx 50% in summer).

Tough, yet soft, Sir Walter has a tight growth habit that will hold out most weeds if kept healthy. It also repairs itself quickly after grub attack, or the appearance of fungus, lessening the “bare brown patch” look.

Sir Walter DNA Certified will stay green in winter in most areas, provided it is fertilised well in autumn and not mowed too low prior to winter. It is extremely drought tolerant, therefore requires less watering than other varieties of turf.

It can be laid all year round, however the warmer months will provide the most suitable conditions for it to establish itself. In winter it will simply take a bit longer.

17 years down the line and following extensive testing, hundreds of thousands of lawn installations and some of the harshest weather conditions to date, Sir Walter continues to thrive. All of our turf is cut into tiles 1250mm x 400mm for ease of laying.

1 square metre (m²) = 2 Turf Tiles (1250mm x 400mm each)

NB. Genuine Sir Walter DNA Certified Buffalo comes with a Certificate of Authenticity and is covered by a 10 year product warranty as part of Lawn Solutions Australia. Conditions apply.

You may just need some professional advice on what you need to do before laying your lawn. Our trained staff at Buchanan Turf & Lee Rowan’s can help you through these initial stages. Tap into our wealth of knowledge and DIY, or alternately get us to do it for you !!


Just like your house is only as good as its’ foundations, your lawn is only as good as its base. Before laying your lawn you should ensure that your soil base is free of weeds, any old grass, stones and debris. The texture of the soil should be crumbly, so you may need to rotary hoe what’s there if the existing soil is suitable, or add some topsoil if not. We recommend Lee Rowan’s Lush Lawn Underlay at a depth of 50mm. Spread evenly, then rake or screed your area to ensure a smooth surface, allowing approximately 25mm below surrounding paths and drive-ways.

You should then fertilise your base with a, multi-nutrient fertiliser that has moisture magnets such as Sir Launcher (Available in 3kg bucket covering approximately 100m², or a 900g bucket covering approximately 30m²). Order some when ordering your turf and it will be delivered at the same time. Simply scatter evenly over the entire area before laying your new lawn.


Laying should start with a continuous strip of turf being placed around the perimeter, then proceeding along the longest edge, across the slope in a brick work fashion, filling in any irregular gaps. If laying on a slope start at the bottom and work your way up, laying as far away from your stack as possible to avoid walking on any freshly laid lawn. The edges of the Turf Tiles should be pushed together but do not overlap so the root system has contact with your soil. You can trim your tile with hedge shears, or a sharp knife to fill unique shapes, or edges.

For the best result you should roll your lawn after it is laid, concentrating on the joins to help it from drying out. (This isn’t necessarily done in most cases and your Sir Walter lawn will still flourish as long as it is watered well during the first two weeks.)


It is paramount that you give your new Sir Walter DNA Certified lawn a thorough soaking immediately after you lay it. If you are laying a large area watering should commence as soon as one section is completed. (A soaker hose is ideal for this). For the first two weeks your new lawn requires extra care, especially water. Initially your Sir Walter DNA Certified should be kept moist, so depending on the weather, up to 4hrs watering per day may be required if hot and dry. Otherwise regular daily watering until root growth has established is all that is necessary, depending on the season and weather conditions at the time you are laying. Taper your watering off gradually to allow your new lawn to become acquainted with its’ new surroundings. Sir Walter DNA Certified is extremely drought tolerant, if humid only water before lunch to prevent any water laying in the sub soil overnight. We suggest deep watering infrequently instead of frequent light watering.



Mowing Sir Walter DNA Certified is a breeze. Wait until your new lawn can no longer be lifted off the ground before attempting its’ first mow. We advise you take 1/3 of the height off the blade of grass when mowing. During the warmer weather you may have to mow more frequently, perhaps even weekly or fortnightly depending on the amount of rain. Once we head into the cooler months the frequency of mowing will decrease but still needs to be regular to keep your lawn in tip top condition. A height of 30-40mm is recommended for a healthy, lush lawn. If part of your lawn is in a shady spot we suggest you mow this area a little higher to allow for more leaf growth to compensate for lack of sunlight.


We recommend you fertilise your Sir Walter DNA Certified lawn 3 times a year. It is best done in October, December and late March/early April. Fertilising your lawn is very weather dependant and also relies on the nutrient levels of your soil.

Have a look at your lawn, if it is a little jaded then it may need some food. Sir Walter Fertiliser comes in 10kg buckets which will cover approximately 400m² and 4Kg buckets which will cover approx 160m². It has the active ingredients that will keep your lawn healthy and strong. A maintenance feed of Lawn Rescue is ideal for the summer months if the weather is hot and dry. It will feed and drought proof your lawn better than any other product on the market.

We also recommend you top dress your lawn in spring every 3rd year. This will not only feed your lawn but even out any dips and hollows. Lee Rowan’s Rocket Top Dressing is the perfect soil free mix of nutrients and should be applied in September for maximum effect.
