EMPIRE Zoysia Turf Maintenance Guide - Recipe To Maintain Empire Zoysia


  1. Option 1. For lawns that receive moderate wear, where good winter colour is desired and low to moderate mowing is desired. Fertilise at the beginning of April and again in mid-June with slow release fertiliser applications at a heavy rate. We recommend the use of our Summer/Autumn blend. Empire™ Turf needs less fertiliser than all other turf types, so all other fertilising applications other than autumn and winter are optional and not necessary to keep a healthy lawn under these circumstances. The benefit of fertilising just in autumn and winter only, is far less mowing. Empire™ turf is very happy with just these two applications every year. Being fertilised well in autumn and winter and shortly mown, results in Empire™ Zoysia having much better winter colour. Longer Empire™ Turf tends to brown off more on the tips. So the best option is to mow short from around the 10th of March; keep it like that till mid-September, then you can let it grow a little longer. If you have shade, or prefer the lawn a little longer, the other option is to fertilise as advised, and if in the middle of winter the tips brown off, simply mow very lightly removing the burnt tips. In regions that get only a small number of light frosts, the tips will not brown. For example, Sydney’s east and inner west, or most parts of Brisbane will not tip burn.

  2. Option 2. For lawns that get high wear, or where you want a super dark green lawn all year round and do not mind mowing a little more. Fertilise in autumn and winter as per option 1, then also fertilise in September to October with a moderate rate of slow release fertiliser. For this time of year we recommend our Spring blend. Empire™ turf does not need fertiliser in summer; however it may be worth considering further optional applications under extreme circumstances. If your lawn receives very heavy wear from dogs or kids, or you want a dark green lawn all summer and do not mind mowing more, you can optionally fertilise again in mid-November, and at the end of February with moderate rates of slow release fertiliser. THE MOST IMPORTANT TIME TO FERTILISE IS AUTUMN AND WINTER.

  3. Option 3. For lawns that you want reasonable winter colour, but do not care if your lawn browns off a little near the middle of winter, or if you live in Queensland where it will generally stay green in winter with just one fertilise, and your main aim is to mow much less. Fertilise at the beginning of April only with slow release fertiliser applications at a heavy rate, we recommend our Summer/Autumn blend. Empire™ turf will still have quick spring green up. Empire™ Zoysia needs less fertiliser than any other lawn type. Option 3 will mean less than a half to a third the mowing of Buffalo turf, and a quarter to a fifth the mowing of Couch and Kikuyu.

  4. Option 4. No fertiliser at all for roadsides or low to moderate wear areas for people who hate mowing, resulting in a lawn that requires only 2 to 4 mows per year. For many years, roadsides have used Empire™ turf all over Australia. In most regions for roadsides by not fertilising, Empire™ turf only needs two mows per year; three to four in Queensland. The lawn is usually left to grow a little longer before mowing, for example 75mm to 90mm. Then it is mown to about 40mm to 50mm high. Empire™ Zoysia will brown off in winter with no fertiliser, but it will green up quickly in spring. Treating the lawn like this will not result in a fully manicured looking lawn, but it will generally look acceptable. University research in the USA shows Empire™ turf can live on very low nutrients compared to other turf types.

    For a greener lawn in winter look at the regional information for QLD, NSW, VIC and SA.


  1. In general, an Empire™ lawn can be mown very short or longer depending on the desired finish. If you want a green manicured bowling green type lawn, regular short mowing will achieve that. As a general lawn, fortnightly spring and summer mowing should be enough, unless it is highly fertilised, then mowing each 10 days may be needed for a bowling green appearance. With no spring and summer fertilising, Empire™ turf can usually be mown every 3 to 4 weeks or so. Mow to a height that does not cause scalping. E.g. 35 to 45 mm.

    Mowing practice can also help keep Empire™ Zoysia greener in winter. Leave at a moderate length for most of the year. If after all the recommended fertilising the lawn browns off in winter, lightly mow the Empire™ turf. Under moderate frosts and even the odd heavy frost, mainly the tips of the leaf burns on Empire™ Zoysia, thus a light mow removes most of the burn making the lawn instantly greener. The best method to keep Empire™ Zoysia greener in winter though, is to mow it short from early autumn and keep it like that.

    A combination of autumn and winter fertilising, and a shortly mown Empire™ lawn will provide good winter colour, particularly for NSW and Queensland. To improve winter colour and the general health of Empire™ turf, it is recommended to dethatch the lawn every second or third spring; around the end of August in Queensland or Sydney, or early September in cooler areas like Melbourne dethatch the lawn. The easiest method is to simply mow the lawn very short, and collect the clippings. Another method is to hire a dethatching machine, or simply lightly top dress the lawn.


  1. Watering your Empire™ lawn in a dry winter can also improve its winter colour. If the ground or lawn is very dry, frosts have a habit of burning the lawn more. Watering after fertilising also helps activate the slow release fertiliser. In the warmer months, water when the leaf starts to dry out. It is better to apply heavy, deep watering. If you get water on soon after the leaf starts to shrivel, it will quickly green up. If water restrictions prevent you from watering, do not panic if the lawn is at least one year old. Due to its deep rhizomes, a mature Empire™ lawn can withstand long periods of drought without dying. It will brown off and go dormant, but when it rains again or it is irrigated it will generally reshoot well and green up. If you live in desert regions or places like Perth with little summer rain, some top up watering is required to keep Empire™ Zoysia alive. In research in the USA by a water authority, Empire™ turf withstood drought far better than Buffalo turf.

Weed Control

  1. Controlling weeds in Empire™ Zoysia is much easier than in Kikuyu, Buffalo and even Couch. Firstly, a healthy dense Empire™ lawn will resist many weed types. If a few weeds do invade, you can simply hand weed them. If it is a greater weed problem, Empire™ turf is more tolerant to chemicals than most lawn types. The following are some types of chemicals that can be used. These chemicals have different labels in each state or country where Empire™ Zoysia is sold, so check label rates and details. Some of these chemicals are available in garden centres, whilst others are mainly available to weed control professionals.
  2. Chemicals that can be used on Empire™ Zoysia

  3. For most broadleaf weeds (flat weeds), use Bromoxinyl + MCPA (Domestic and Professional), Dicamba + MCPA (Kamba M) (Domestic and Professional), or Spearhead (CLOPYRALID + DIFLUFENICAN) (Professional).
  4. For many grass weeds, including annual grasses such as Kikuyu, Paspalum, Mullumbimby Couch and Sedges, use DSMA (Domestic and Professional).
  5. To kill Nut grass and other sedges use Sempra (Professional).
  6. For a combination of some grass weeds and some broadleaf weeds try Monument (Professional).
  7. As a pre-emergent to stop weed seeds germinating, for established grass only, not for use when turf is establishing, use Barricade (Prodiamine) (Professional) or Ronstar (OXADIAZON) (Professional).

Pests and Diseases

  1. Empire™ Zoysia is far less susceptible to lawn grub attack than Buffalo, Couch, and Kikuyu, however damage can occasionally occur. If you see insect damage, treat accordingly. Generally, Lawn Grubs prefer Buffalo, Couch and Kikuyu to Zoysia though, as Zoysia has a biology that makes it far less attractive. Army Worm is rare in Empire™ turf, but can happen. If you see masses of caterpillars walking across your lawn, wait 20 to 30 minutes or so and see if they are just travelling to your neighbour’s lawn, and leaving your Empire™ lawn mainly alone. Usually this will be the case, but if in the unlikely event that they do start eating it down, use Baythroid Lawn Grub & Garden Insecticide. Occasionally in Queensland, like some other turf types, Empire™ Zoysia can get Mealy Bug; brown patches occur with a milky residue. Although this is rare to occur on Empire™ turf, it’s still possible, so if you see this use Confidor Lawn and Garden Insecticide from Yates. This will also control Black Beetle, which also are less likely to prefer Empire™ turf to other lawns, and actually rarely cause damage in an Empire™ lawn. We have, after many years, yet to see any fungus or diseases on Empire™ turf on the East Coast of Australia that affect other lawns. If you do see any please let us know, as we always strive to help customers who use Empire™ to have the knowledge to look after their lawn in the best way possible.
