Nara Zoysia - Turf Grass

Origin: Nara Zoysia is an all purpose Australian native lawn grass. ( Zoysia macrantha ‘MAC93′ PBR )

General Information: Nara native turf is a great all purpose turf that can handle many conditions. It is the only general native Australian turf. The only other native turf is Dryarna, but it is only grown for drainage channels because it only survives in or next to shallow water. Unlike Nara, Dryarna is not suitable for general turf areas. Nara is the perfect compliment for any native garden or landscape.

Features

• Superior Drought Tolerance: Nara is a low maintenance grass that is naturally very drought tolerant. In drought studies, Zoysia macrantha was found to be more drought tolerant than Buffalo and Couch turf. It is generally a coastal grass but has been proven to work well many hundreds of kilometres inland.
• Superior Salt Tolerance: Common Zoysia macrantha is very salt tolerant, so it is no surprise that Nara has this quality as well, although Nara is better watered with fresh water when possible. In tests, Nara had much more salt tolerance than Empire, which is known for its excellent salt tolerance in comparison to other grasses. When Nara was tested and compared to a selection of common Zoysia macrantha types in breeding, it had salt tolerance at the mid to lower end of the species. Not as high as some, but still much higher than Couch, Buffalo and Empire. This is only important because people need to know it cannot handle growing in sea water. However, growing close to the beach or on waterfront properties is not a problem.
• Growing Areas: It is native to Australia, from northern Queensland all the way down to Tasmania, to the centre of Australia and Adelaide. Zoysia macrantha is well suited to most parts including Perth, where it has performed very well, making it ideal for your local Australian lawn. Nara is currently being released it in the USA. It performs very well there, and is admired for its beauty. Nara is well adapted for all parts of Australia, except the Alpine regions, although it can handle down to Minus 12 degrees Celsius in USA tests, which is colder than Canberra.
• Mowing: Based on research and observations Nara will need about 20% less mowing than Buffalo, 30% less than Couch and 45% less than Kikuyu. It is faster growing than Empire Zoysia.
• Nara can be mown exactly how you would mow Couch, Kikuyu or Buffalo. Short, medium or long. In general it is better to not mow too short as it stresses all lawns, especially in drought. Can be mowed to 2-5cm in sunny areas and 5-7cm in shaded areas.
• Fertilising: It requires only one fertilise per year. It is a Zoysia macrantha, which is only found in Australia. Overseas Zoysia types such as Empire (a japonica type) also only require once a year fertilising. If they are subject to a lot of wear twice a year fertilising is recommended on all Zoysia.
• Weeds: Nara is very good at competing with weeds. You can also use any chemical that works on Couch. Nara is much better than Buffalo with chemicals as you can, for example, take out Paspalum with a selective spray.
• Sun/Shade: Buffalo works in 65-70% shade. Nara works in 50-55% shade. Couch and Kikuyu only work in 20-25% shade.
• Looks/Texture: Nara is beautiful. It is a fine textured lawn, but scalps less than Couch when mown. People choose it over Couch, Kikuyu and Buffalo on looks alone.
• Edging: Nara requires less garden edging than Buffalo, Couch and Kikuyu, making it less invasive for the garden, although Empire Zoysia does require slightly less edging than Nara native turf.
• Colour: Better winter colour than Couch and many Buffalo types. Nara browns of quicker than Palmetto, Sapphire and Kikuyu which are well known for their excellent winter colour. In Western Sydney at Richmond this year it was dormant for about 7 weeks. So there a few grasses that have better winter colour, but compared to many it is better.
• Wear Tolerance: It has better wear tolerance than Buffalo, Couch and Kikuyu in full sun, although Couch and Kikuyu recover better from wear as they grow faster. In semi shade Nara has better wear tolerance than Couch and Kikuyu.
• Drought Tolerance: Nara has vigorous deep rhizomes, it is far more drought tolerant than non rhizome grasses such as Buffalo. Buffalo will hold its colour in drought a few days longer than the Nara, but will die much quicker in a hot prolonged dry spell. Nara has developed extreme drought tolerance from its parentage. Millions of years growing in Australia’s hot, dry and humid climates has made it a real survivor.
• Diseases: Nara rarely gets disease, and copes very well with humid and dry climates. In colder areas and wet winters like many grasses, it can occasionally develop a small sign of rust, but this is generally hidden amongst the leaves of a mature lawn. Nara hides rust much better than many other types, so it is a safe choice. Nara seems to cope well with our bugs and insects, probably because it built up immunity over the millions of years of development as a native species of Australia. A few introduced pest species and the odd native one may cause problems occasionally. Nara seems to be far more resistant to black beetle, army worm and web worm than Couch, Kikuyu and Buffalo. Resistant does not mean immune, so it can sometimes get munched on. Again, because it has rhizomes, it will re-grow better than Buffalo.

Installing Nara Native Turf

Nara prefers to be installed when the weather is not too cold. It is best to avoid laying Nara in the following months in certain regions:

Avoid laying 25th April - 25th August: Tasmania, Victoria, SA, WA;

Avoid laying 15th May - 15th August: Sydney; and

Nara can be layed anytime of the year Brisbane and north.

This is the same for all Zoysia types. Nara can actually be laid in the cooler months in Sydney provided the turf is kept moist till it roots out, but as it takes up to 7 weeks to root out in winter, we feel it is best to wait for warmer weather. In warmer weather Nara will establish relatively quickly from turf. In early spring or autumn it may take a week longer than other turf types to establish, but what’s a week compared to a lifetime of low maintenance?

Seeding

The first year after laying Nara, it will seed quite a lot. The second year it settles down, provided you fertilise in spring. It will generally have a burst of seed in early spring and won’t seed for the rest of the year. This is a distinct advantage, as Nara will only need more mowing in early spring to remove seed head, compared to Couch and Buffalos that will need mowing to remove seed head at many times of the year.
