"EMPIRE™ ZOYSIA Turf– It just keeps looking good"
Probably the hardest lawn in the world to wear out. Only the better Buffalo varieties have more shade tolerance. Almost indestructible rolls or slabs. With such little mowing required, it is the ideal lawn for slopes.
Ozbreed is pleased to introduce EMPIRE™ ZOYSIA, a selected cultivar of Zoysia japonica, chosen specifically for its ability to reduce production costs while demonstrating very desirable growth characteristics. Reduced production costs are achieved by EMPIRE™'s rapid expansion rate, reproduction from rhizomes, and its natural chemical resistance for easier weed control. Unlike other Zoysia grasses, EMPIRE™ is not too slow. In fact compared to other Zoysias lawns, EMPIRE™ is super fast, however EMPIRE™ still requires less mowing than Couch, Kikuyu, and Buffalo turf.
EMPIRE™ demonstrates superior dark green color, low thatch build up due to its wide bladed leaf (compared to other Zoysias) and open growth habit, natural chemical resistance to MSMA, 2,4-D, and Fusillade II, and good drought tolerance. EMPIRE™ was discovered in Brazil, and unlike other Zoysia varieties, has proven its ability to thrive in hot, humid conditions as well as colder climates. EMPIRE™ has performed well in sandy and clay soil types with aggressive growth from its runners and rhizomes, but can be mowed with a standard rotary mower due to its broader leaf and open growth habit. It requires less maintenance and mowing than other grasses, and is a very efficient water user. This versatile turf grass thrives in all climatic regions of Australia, from Darwin, to Tasmania, from Sydney to Perth, and would even survive in places where the temperature drops to 20 degrees below 0.
Information on Common Zoysia (compared to EMPIRE™)
Zoysia grass is extremely drought tolerant. Although it does turn straw colored under severe drought conditions, it has the capacity to respond to subsequent irrigation or rainfall. Its water requirements are similar to those of Couch grass. The leaf blades of Zoysia grass are among the first to roll under drought conditions, thus it tends to conserve moisture more effectively than other species. Zoysia grass also has a deep root system allowing it to more effectively extract water from greater soil depths. EMPIRE™ remains looking good in dryer conditions than other Zoysias. EMPIRE™ not only survives drought, but keeps looking great for longer.
Zoysia grass is nearly as salt tolerant as Bermuda grass. It is widely grown along sandy seashores where drainage is adequate. Zoysia grass does not tolerate poorly drained soils whether they are saline or otherwise, until now. EMPIRE™ ZOYSIA does well in most soil types, including heavy poor draining soils.
Zoysia grasses are among the most wear tolerant turf grasses. However, their slow rate of growth gives them very poor recuperative potential. Until now. EMPIRE™ has a great recovery rate. EMPIRE™ has changed the way people look at Zoysia.
Winter Colour Dormant in Colder areas (e.g. Canberra), Good in Sydney, Perth, Brisbane, Adelaide, etc.
Hot Weather Tolerance Excellent / thrives in hot humid and desert areas
Cold Tolerance Excellent. You would have to go to the top of Mt Kosciusko to find a place in Australia where EMPIRE ™ won't live.
Moderate to good, only better Buffalo varieties have more
Salt Tolerance Excellent / thrives near coastal areas
Mowing Height 25mm to 50mm / can be mowed 12mm to 25mm when maintained like a bowling green.
Recovery from Injury Excellent / runners and rhizomes fill in damaged areas
Use Lawns / residential, commercial, sports, parks, roadsides
Root Structure Fine, deep, massive, rhizomes spread underground
Drought Tolerance Excellent once established
Pest resistance Excellent lawn grub resistance
NOTE: Empire is more lawn grub resistant than other turf types, but this does not mean it is immune to lawn grub. If symptoms similar to lawn grub are present, consult with your lawn care professional.

Composting is nature’s own recycling program. In time, organisms will break down the ingredients listed below into rich, dark crumbly compost - nature’s own nutrient-rich fertiliser.
How does composting work and how long does it take? Natural composting, or decomposition, occurs all the time in nature. Home composting generally takes two months or more. The more you turn and mix the contents - adding air in the process - the more rapid the composting action will be.
The right conditions include the right ratio of nitrogen to carbon - equal amounts of ‘greens’ (kitchen scraps) for nitrogen and ‘browns’ (fallen leaves and woody material) for carbon the right amount of water (feels like a damp sponge) good drainage (to remove excess moisture) enough oxygen (turned often) What can you compost at home? Vegetable and fruit scraps Fallen leaves Grass clippings Finely chipped branches Used vegetable cooking oil Tea leaves, tea bags Coffee grounds Vacuum cleaner dust Egg shells Sheets of newspaper Paper bags Shredded paper What can’t you compost? Metal, plastic, glass Meat and dairy products (attract rodents) Large branches Bones Plant bulbs (need specialised treatment) Droppings of meat-eating animals (e.g. dogs) Grubs in your compost? Sometimes in compost bins there are many segmented brown grubs. These are the larvae of the beneficial Soldier Fly. They are not pests, nor will they cause health problems.
Mulches Mulches can prevent up to 73% evaporation loss and they are one of the cheapest and easiest ways to make the most of water in the garden. The best mulch is a well-rotted compost which will also improve the soil structure and stimulate the biological life of the soil. Place the mulch away from the trunk to prevent collar rot. Do not apply mulch more than 75-100 mm in thickness or water may not easily penetrate into the soil.
This article is written for those who have a problem with their cycad plant, want to avoid the common maladies of growing cycads or would like general sago palm care tips. In this article we discuss the problems that we’ve seen frequently and advise as to potential remedies that seem to help. It is meant to stimulate the reader into inspecting his plants for yellow leaves, brown tips, rot, etc., and coming up with therapeutic modalities for his plants. The better one gets at this, the better grower he will become.
Inspect your plant
In growing cycads, it is very important to make a habit of looking at your plants. Inspection is key to good growing of cycads. They will usually demonstrate to you that they have a problem. However, it helps to know what to look for while inspecting. This can lead to your diagnosing the problem, or at least let you know something is wrong.. Once you establish what the problem is, you can set out to solve it. Described below are some of the things that you can look for while inspecting your cycads. Be aware that different climatic areas may see different problems than we've seen here in Southern California. However, most of the problems discussed below are quite universal to all growing areas. The problems of insects and pests is not dealt with here and will be discussed in a future article.
Encephalartos transvenosus, suspected of rot.
Bottom rot on Encephalartos caudex.
You see visible rot on your caudex or roots: Sometimes one might see rot on the trunk of a cycad. Or, you might see it on inspecting a caudex in pumice that you are trying to root out. Obviously, this requires you're bare-rooting the plant to inspect the roots and base of the caudex. Unfortunately, rot can hide and be deceptive, even starting in the most hidden, deepest roots. With rot, the first thing one notices is that the caudex or root tissue is soft. Rot manifests itself as a dark tan to brown/black color in the caudex or trunk . Rotting roots tend to be soft, darker colored, and lacking secondary roots coming out. This is opposed to light, fleshy healthy roots . Usually the rot involves the lower caudex in it’s subterranean area or the roots. Rot can cause cycads to decline or possibly die if it is not addressed. If you find rot on your caudex, use a sharp, sterile cutting tool (knife or saw) to remove the rot. Cut the rot away until you have only hard tissue that is whitish or light tan in color. Note: in some cases you may not find whitish or light tan tissue; in such cases, cut back to hard tissue. Be careful, if you cut the caudex too much you risk the plant dying. If the rot is on the roots, one needs to individually remove involved roots, dissecting up to clean, healthy tissue. Below are guidelines to the treatment of rot after you've dissected it away.

Rooting hormone brand Take Root; a combination of root stimulant and fungicide.
General guideline in the treatment of tissue rot:
1) After you have cut away the rot (trunk or roots), soak the plant in both a fungicide and root stimulant. First soak your plant in a fungicide, like Daconil, for 30 minutes. Always follow manufacturer's instructions about usage and safety on any chemical. Next you will want to soak your plant in a root stimulant, like DipN’Grow, vitamin B1 or B complex (most liquid root stimulants will work), for 30 minutes. The reason why I recommend soaking the plants for 30 minute intervals is because it allows the caudex to absorb both the fungicide and root stimulant into its tissue 2) Sprinkle a powder root stimulant, like Take Root, onto the base of the caudex and/or the root(s).
3) You should now seal the cuts with an agricultural tar. This assists in keeping the cut surface clean and also helps to protect from future rot. Melted wax preparations can also be used. 4) We use new clean pumice (or scoria) to re-establish the plant. It is a dry medium and you are less likely to incur rot or other problems. This typically means submerging the treated area of trunk or roots directly into the pot of pumice. If pumice is not available, coarse sand can work. Use a pot that is not overly large for the caudex. 5) The time it takes to reestablish your plant can be three to six months or even longer. Failure will be evidenced by the progression of the rotting tissue and failure to establish leaves or roots. You may wish to bare root the caudex for inspection from time to time. One must repeat the cycles above if rot is rediscovered.
Caudex that hasn't done anything in a long time.
The top of your caudex is soft This is an ominous sign. It usually means the caudex is in the process of or about to collapse and die. It is usually due to rot and the plant is usually near death. One would typically see the leaves turn brown and fall downward . They may shrivel. On grasping and pinching the crown of the caudex, it will be soft and compress inwards. It might actually collapse beneath the pressure of the fingers. This often means the demise of the entire plant. If the softness to touch is minimal, quickly treat the crown with a drenching of fungicide, and repeat on a regular basis. If the crown is collapsing, one can dissect away the crown of the caudex until healthy tissue is found. Often this is unsuccessful. The mechanics of doing this are discussed elsewhere, but one would be working from the top of the caudex downward. If one is lucky, new suckers will emerge from this dissected level and the plant will survive. More often then not, this plant is bound for the garbage can and is terminally ill.

E. transvenosus, inspecting caudex for rot and noting softness to the crown of the plant.
E. transvenosus, rotted caudex. Note it falls apart with ease. This caudex is dead.
An unrooted caudex does nothing We’ve found that a healthy caudex can take anywhere from six months to two years to establish adequate roots for survival. Some species are faster than others. For instance, Encephalartos horridus established quite quickly while Encephalartos inopinus gets roots much more slowly. Sometimes the latter will even throw leaves prior to establishing roots. This certainly makes one apprehensive, but it is not always a fatal observation. However, sometimes months and years go by and nothing happens; no roots, no leaves. The first thing to do is to inspect the caudex. Feel it in your hands. Is it firm? Is it still heavy in the hand? Does it feel light? Firmly press the sides of the caudex. Does it collapse somewhat, especially toward the crown? When a caudex goes bad and visual inspection shows nothing, rot is often most evident near the crown of the plant or sucker. Are the cataphylls loose? Pull on them gently. Do they easily pull out? Try float testing the caudex. Unobserved central rot can make the caudex float. If everything seems OK and you find nothing, all you can do is place the sucker back in pumice and wait. A rooting caudex throws leaves before it roots This is always a worrisome problem. It is never the ideal scene, but sometimes happens and can still result in a healthy rooted plant. We always like to see vigorous roots before a throw of leaves. This can occur just because of the natural cycle of the offset. Let’s say it was about to throw leaves and you removed it for propagation. It will continue to leaf out regardless of being removed. Other times it happens six or twelve months after sucker removal and yet before rooting. In either case, it poses a risk to the new caudex. It is generally agreed that there is a risk of desiccation and death of the caudex as the leaves lose water and the caudex has minimal ability to absorb water without roots. Also, the leaves don’t have a nutritional flow except from the caudex. The throw of new leaves might have used up the energy reserves of the caudex. Once observed, the problem is what to do. Remember to inspect for and treat any rot. One may treat with fungicide and certainly place the caudex back in pumice. But, what of the leaves; remove them or leave them in place? There is no perfect answer for this, but most growers would remove all or part of the leaves thrown. In actual fact, usually these leaves will abort soon after throwing and seldom do they persist as healthy leaves. Sometimes the collapse of these leaves is rapidly followed by a collapse of the caudex. Yet, if they survive, could they not be able to offer some photosynthesis and creation of energy? For this reason, some would say remove all of the leaves except a few and cut those remaining leaves in half. Once repotted back into pumice, carefully avoid watering the crown on such a plant.

Encephalartos, healthy caudex but no roots and no leaves as of yet.
New leaves shorter than new ones.
Leaves are shorter than normal If your leaves emerge shorter than they did the last time, there can be a few problems:
a) If you are acclimating your cycad (working it out into sun), the new leaves may be shorter than those which flushed in a shadier environment. This is not a problem; your cycad will grow out of it. b) If this is the first throw of a recently established sucker or a recently transplanted cycad, short leaves can occur. This will change with successive throws. c) A throw of leaves in the coldest part of the winter can stunt their length. You might see this on a recently imported and established caudex whose "biological clock" is set to another hemisphere. c) Leaves emerging shorter can also be an indication of a cultural problem. This could be nutritional requiring treatment with fertilizer or microelements. It could be from a poor soil mix or poor soil aeration. Or, it could be a symptom of caudex or root rot. If you think it is indicated, carefully remove that plant from its pot and wash away the excess dirt with a hose. Inspect the roots or caudex for rot. With a plant in the ground, gently rock the cycad to see if it is loose in the ground, suggesting root rot. You can also check the trunk of your cycad to see if it is soft in exposed areas. If rot is found, treat as described elsewhere in this article. Keys to good culture.
How to avoid problems
“An ounce of prevention is worth a pound of cure”. It might even be that it’s worth many pounds of cure with cycads. Below are some simple rules to follow.
This is one of the most important things you can do. Follow the guidelines mentioned previously and practice observation, especially watching for problems or failure to thrive. Usually you can find the problem and fix it.
Growing the right cycads
Growing the right cycads for you area is important. This will involve your talking to someone or doing a little research on your own, but it can make a huge difference in your garden. You will find that some cycads want a tropical environment where some want a dry one. Fortunately for us in Southern California, we can grow most cycads. Our limitations here are with those cycads with the most tropical demands. If you live in a temperate or colder area, tropical Zamias might prove impossible without a greenhouse. You might also find that South African species of Encephalartos grow better than those from Central Africa. Also, very humid climates such as in Miami or the Tropics might find arid growers like Encephalartos horridus prone to rot. This might require special preventative cultural techniques. For the greatest chances of success, get species right for your area.
Drainage, drainage, drainage
Regardless of your soil type, always maintain good drainage. The soil should never be waterlogged. Sand, pumice and gravel help promote drainage. Very fine sand, leafy organic material and clay-type topsoil slow it down. If it is impossible to offer good drainage in the garden, mound up you cycads above the soil line so you can control the water content of the soil.
Either make or amend you soil to create good drainage. See our article on cycad soil for specific formulas. Remember that the organic components of cycad mix can break down, resulting in “muck” at the bottom of the pot or an impediment to drainage. Repotting is the remedy for this problem. This is important for container culture. In the garden consider amending with sand. If you can’t buy or obtain materials for a good cycad soil, think about using a cactus and succulent mix. These might suffice.
We have seen many promising cycads stall because they have lost their sunlight. This is usually the result of competitive more rapidly growing plants. If a species wants sun, remember to maintain it. Loss of sun will lead to a plant that just sits there and doesn’t do much of anything.
Fertilizing is an important part in growing any plant. The key is to know what kind, how often and how much you should fertilizer you should use. We recommend using a slow-release fertilizer like Osmocote, using an N/P/K ratio that is 3-1-2 or 3-1-3. An example of a good fertilizer might therefore be 18:6:18. You should fertilize once every three to four months, depending on your formulae and release rate. I always recommend that you use a little less fertilizer than what is suggested on the bag because you don’t kill plants with too little fertilizer, but you do with too much.
Watering is an important part of growing cycads, because there’s hardly a cycad that likes to have wet feet. Get use to inspecting your garden soil or the soil in he containers. Don’t let it stay too damp. Drying out near the surface is preferable on most species. Typically, watering frequencies for temperate weather is about once, or possibly twice a week during hot weather. During the winter, once every week or two is usually adequate. For desert type environments, adjust the frequency depending on the soil moisture content. For tropical environments, try to avoid conditions where the plant and soil are continually damp. Mounding might be necessary. Or, overhead shielding during the rainy season might be needed. Also, regardless of where you are, water the garden or container soil, not the crown of the plant. Repetitive watering of the crown will lead to rot. This means that frequent overhead sprinklers can be a problem. Ground bubblers on timers can be great for the cycad garden. This also explains why climates with daily monsoon seasons can lead to difficulties with some species.
In a greenhouse environment, ventilation to provide adequate air movement around your cycads will help prevent mold and rot. Stationary oscillating fans or intake/exhaust fans can help accomplish this. Poor ventilation often causes mold and scale problems in the greenhouse.
Get into the habit of inspecting your plants. If you see fungal problems or rot, treat it early. Fungicides can also be used prophylacticly to avoid problems if you are anticipating them. This would especially apply to plants grown in a humid greenhouse.

In this article we have covered many of the basics in protecting your cycads. The great thing about it is that cycads really do not take much maintenance at all. You could say that they almost thrive on neglect. Just be careful when you water, don’t fertilize too much and make sure that your cycad is in a quick draining soil and has adequate light. If you do the things discussed above, you should become a successful cycad grower.

Azalea Lace Bugs - fact sheet The Azalea Lace Bug (Stephanitis pyrioides), an insect originating from Japan, is a signicant pest of azaleas and rhododendrons in many regions of the world where these plants are cultivated. The bug especially attacks plants growing in sunny, exposed situations. Symptoms of lace bug attack The feeding activity of every stage of the lace bug life cycle produces a widespread grey-whitish/silvery mottling on the upper surfaces of the leaves, similar in colour but coarser in texture to that caused by spider mites. Adult and juvenile lace bugs feed on the undersurfaces of azalea and rhododendron leaves. The mottling is usually so severe that leaves that have been attacked are permanently disfigured. Leaves will die and fall from the plant well before their time. Sticky brown patches or ‘varnish’ (excretory products of the lace bugs) appear on the undersides of the leaves. The Azalea Lace Bug is widespread throughout Australia. Life cycle The lace bug has at least two (and possibly four) generations per year in Australia. Adults reach 4-6 mm in length. They have clear, heavily veined wings - hence the insects’ common name. Juvenile lace bugs are wingless, spiny, have long antennae relative to their body length, and have a black and tan mottled colouring giving them an overall dark appearance. There are probably five nymphal instars. Nymphal moult skins often remain stuck to lace bug varnish on the undersides of leaves. Lace bugs overwinter in the egg stage, hatching when conditions improve for them in the sping. Eggs are inserted into the mid-vein on the underside of the azalea or rhododendron leaf as they are laid. They have a brown protective covering which hardens on contact with air. Control Lace bugs are particularly difficult to control. There is currently no known effective biological control agent (e.g. a parasitic wasp). There are some pesticides that are registered for the control of this pest.

General information Scarab beetle larvae, also known as white curl grub (or cockchafer in southern states), are a serious lawn pest. The signs of infestation are easily confused with other pests, diseases and disorders in turf and present as a general yellowing, then browning, followed by the death of lawn. Overview Pest characteristics In subtropical areas, lawn injury is commonly seen from November through to January. The most common causal agent is African black beetle (Heteronychus arator), although a number of native and non-native scarabs look similar and produce comparable damage. These include pruinose scarab (Sericesthis geminata) and Argentine scarab (Cyclocephala signaticollis). If in doubt, have the pest formally identified. Third instar African black beetle larvae grow to 20-25 mm in length before pupating in the soil. They have an orange-brown head capsule. Oval-shaped, shiny black adults, 12-15 mm long, emerge during February, feeding on stems just below ground level. They are less active through winter and mate in spring after the female has reached sexual maturity. Only one generation is produced each year. Deceptively, different larval stages are sometimes found in the soil. This is mainly due to eggs being laid at different times. Correct names White curl grub, scarab beetle larvae, lawn beetle larvae or cockchafer are the correct common names for the juvenile stage of lawn beetle. However, white curl grub is sometimes incorrectly referred to as 'lawn grub' and 'witchety grub'. 'Lawn grub' is a colloquial term for surface-dwelling caterpillars such as sod webworm, army worm and cutworm, which become moths. The true witchety grub is the wood-feeding larva of two families of giant Australian moth. Symptoms White curl grubs have a characteristic 'C' shape and three pairs of legs. They live underground, protected by soil. Animals such as magpies, crows, wood duck and other carnivorous birds, bandicoots and even foxes enjoy this food source. Damage from animal feeding can be the first indicator that the insects are present. Some white curl grubs are parasitised by the yellow (hairy) flower wasp (Campsomeris tasmaniensis) in southern Queensland. This 30 mm-long hairy wasp with yellow and black banding on its abdomen can also act as an indicator of the presence of beetle larvae. The late second instar and third instar phases of the beetle’s lifecycle are the most damaging to turf. These larger larvae are voracious feeders on roots and underground stems. The adults also feed on turf, but cause much less damage. What often differentiates white curl grub damage from other types of lawn dieback, such as that caused by drought or water repellent soils, is that the lawn starts to slip or roll up like a carpet. If this symptom is detected it is time to bring out a large corer or shovel and dig for beetle larva. A problem infestation is generally regarded to be 25 or more white curl grubs per square metre. If fewer larvae are present, healthy turf is likely to outgrow the minor damage it will sustain. Under heat and drought stress, the problem may be exacerbated by poor rates of regrowth and smaller numbers of larvae can cause significant damage. Host range African black beetles establish in a wide range of grasses including green couch, blue couch, soft leaf buffalo grass and kikuyu. The insect has a broad range of dietary preferences and larvae will attack, among other things, strawberries, pineapples, potatoes and grape vines. Detection Control measures are most effective when insect activity is monitored. One way of doing this is to moisten a hessian bag or piece of carpet and place it on the lawn overnight. In the morning the adults can be collected and disposed of. Check for adult beetles from late spring to early summer when egg laying commences. It is thought that garden lighting may be helpful in attracting and detecting adult beetles. However, this may have the unwanted side effect of increasing egg laying activity in adjacent lawn areas. Turning off unnecessary garden lighting may reduce pest numbers. Biological controls Some householders encourage carnivorous birds into their garden to control the pest. However, if the white curl grub problem is severe, bird feeding can cause extensive damage in its own right. Free range poultry will also keep pest numbers in check. A bucket of soapy water made with a biodegradable detergent can be poured onto affected areas, encouraging the larvae and beetles to move to the surface where they might be picked off by birds. Effective control of later larval stages is only achievable with insect killing nematodes, known as entomopathogenic nematodes (ENs). They are active only against specific soil-dwelling insects, safe to handle and safe for plants. These nematodes were commercialised in 1999 after extensive research by the CSIRO Division of Entomology in Canberra. ENs for African black beetle are raised in a laboratory and shipped in a dormant state. When received, the ENs must first be hydrated in water, and then lightly stirred to avoid settling. The suspension can then be watered onto a pre-moistened lawn. This needs to be done in the late afternoon because ENs are sensitive to the sun’s ultra-violet rays. Upon release, the nematodes sense their target, move to it, and enter their prey through openings in its body. They then release bacteria that feed on the inside of the larva. The bacterium nurtures the nematode population, which builds up to the point where the larvae dies, rupturing to release a new generation of ENs into the soil. Chemical control Read garden chemical product labels carefully prior to purchase. Make sure the product is registered for use on home lawns for lawn beetle. There are three stages of the lawn beetles’ lifecycle for which a chemical may be registered. Use the chemical on the correct part of the lifecycle, strictly following the directions on the label. Chemical control measures are most effective on newly hatched larvae. The presence of adult beetles is a cue to check the soil for early stages of the lifecycle, which are vulnerable to imidacloprid (Confidor) and thiamethoxam (Meridan) applications. The organophosphate, chlorpyrifos (various lawn beetle and lawn grub formulations), is registered for the control of lawn beetle larvae and adults. In practice, the chemical is only effective on larvae if it infiltrates the soil and reaches the insect. It does not work well on larvae with high body fat. In addition, chlorpyrifos is highly toxic to the user and needs to be handled with caution. Prior to treatment, water the lawn well to bring the larvae closer to the surface. Penetration of chemical will also be enhanced by mowing, then raking out thatch, before treatment. The adult beetle is easier to control. Other chemicals registered for the control of adults have the active ingredients beta-cyfluthrin, bifenthrin, cyfluthrin (Baythroid) and diazinon (Pennside). Synthetic pyrethroids (such as bifenthrin and cyfluthrin forms) are safer to handle than organophosphates such as diazinon and chlorpyrifos. Pennside has been micro-encapsuled, reducing its toxicity to users.
