Garden edging in New South Wales generally costs $15 to $35 a metre for plastic, $45 to $110 for steel, $40 to $150 for timber sleepers, $45 to $90 for machine extruded concrete kerbing and $120 to $350 for sandstone. Most households choose their edging on how it looks and then wonder why the lawn is back in the garden bed a year later. The grasses used across most of this state, kikuyu, couch and buffalo, spread by runners travelling along the surface and underground, and shallow edging simply will not stop them. Depth beneath the soil surface is what genuinely does the work, so ask for a figure rather than a description. A mowing strip that a mower wheel can run along is the other decision worth making deliberately, since it removes whipper snipping from that line entirely. Anything retaining more than a small level change stops being edging and becomes a retaining structure, which brings drainage and approval questions along.

Cost Depth: What Drives Garden Edging Prices in NSW

Material sets the base rate and the spread is wide, running from plastic at a few tens of dollars a metre to cut sandstone at several hundred. Depth of installation then drives the labour, because edging that only sits on the surface goes in quickly while a trench deep enough to stop grass runners means excavating the full length by hand or machine. Ground conditions decide how fast that trench goes in, and a run through soft soil is a different job from one through clay, rock or old builder's rubble. Curves cost more than straight runs in rigid materials such as brick and sleeper, and less in flexible ones such as steel and extruded concrete, which is why the shape of your beds influences the sensible material choice. Access affects delivery, since sandstone and sleepers are heavy and a rear garden reached through a side gate means barrowing everything. Removing existing edging is a separate line, and old concrete costs considerably more to take out than plastic does.

As an example, twenty metres of steel edging along straight beds in soft soil typically costs $900 to $1,800 supplied and installed. The same run in treated pine sleepers lands at $800 to $1,600, while hardwood sleepers reach $1,400 to $2,600. Machine extruded concrete kerbing over the same distance sits at $900 to $1,800 and handles curves without any additional cost, which is why it suits flowing bed shapes. Brick or paver on edge laid on a concrete haunch reaches $1,400 to $3,200 and gives you a mowing strip at the same time. Sandstone runs $2,400 to $7,000 for twenty metres depending on whether it is sawn or split face. Removing an old concrete edge adds $15 to $25 a metre before any new work begins.

Garden Edging Costs in NSW

Plastic edging runs $15 to $35 a metre installed across New South Wales, steel $45 to $110, timber sleepers $40 to $150 depending on species, machine extruded concrete kerbing $45 to $90, brick or paver on edge $70 to $160 and sandstone $120 to $350. Removing existing edging adds $10 to $25 a metre, with concrete at the top of that range. Those figures assume reasonable soil and access, both of which vary enough to move a quote considerably. Have the material and the labour itemised where you can, since that reveals whether a difference between quotes is the product or the depth of work. Rates for the wider trade sit under landscaping costs. Length and access are the two site factors most likely to move a figure, and both are easy to state accurately when you enquire.

The mistake almost everyone makes is choosing on appearance and discovering the functional problem afterwards. Edging that looks the part and sits shallow in the ground will have lawn growing through the garden bed within a season, because the grasses used across most of New South Wales spread by runners rather than only by seed. Kikuyu in particular travels both over the top of an edge and underneath it, and a hundred millimetres of plastic pressed into soft soil stops none of that. Photographs online rarely show how deep anything is installed, which is part of why the functional question goes unasked.

The second decision worth making deliberately is whether the edge doubles as a mowing strip. A flush strip of concrete, brick or paver that a mower wheel can run along means the lawn is cut right to the bed every time and no whipper snipping is needed at all. That saves more ongoing effort than any other choice on this page, and it costs more up front than a simple upstand edge. Households who mow their own lawn notice the difference immediately. On a lawn cut by a contractor, the saving appears in their time rather than yours, which is worth raising with them.

What Edging Actually Does

The most useful job edging performs is containment, holding mulch and soil inside the bed rather than allowing them to wash and spill onto lawn and paths. A bed with a proper edge holds a decent depth of mulch, which suppresses weeds and retains moisture, while an unedged bed loses that material every time it rains heavily. That single function is worth the money in a Sydney summer where mulch depth is the difference between plants coping and not. Mulch that stays in place also keeps working, since a thin scattered layer suppresses very little and a maintained depth suppresses most germination. Beds beside a driveway or path benefit most, since that is where spilled mulch is most visible and most often swept away.

Keeping grass out of beds is the second function and the one most edging fails at. It requires the edge to present a barrier both above and below the soil surface, since running grasses travel by surface runners and underground stems. A shallow edge stops neither for long. Depth is what does the work here, and it is the specification detail that separates edging that keeps looking good from edging that becomes a decorative line with kikuyu growing through it. Owners who have replaced shallow edging twice usually specify depth the third time without needing to be told. It is also the function owners judge the whole installation by two years later.

Definition and appearance matter too and it is reasonable to care about them. A clean edge makes a garden look maintained even when the planting is ordinary, gives beds a deliberate shape, and creates the contrast between lawn and bed that reads as tidy from the street. Landscapers use edging for exactly this reason on properties being prepared for sale, since it delivers a disproportionate visual improvement for the money. A crisp edge also makes a modest garden look cared for, which is why it appears on almost every pre-sale presentation list.

Practical protection is the fourth role and it is easy to overlook. An edge stops a mower wheel dropping into a bed, protects plants from being clipped, keeps gravel and decorative stone where it belongs, and gives a whipper snipper something to work against rather than shaving soil away. On a bed adjoining a path or driveway, it also keeps the two materials separate. Related surfaces sit under concrete pathway work. Plants at the front of a bed survive considerably longer where a mower cannot reach them.

What edging does not do is hold back significant amounts of soil. An edge is a border, not a structure, and anything retaining more than a modest level difference is a retaining wall with the design implications that carries. Owners who install sleeper edging and then backfill against it to create a raised bed have quietly built something else. That distinction is covered further down and in raised garden bed work. The distinction matters because one is a landscaping choice and the other carries approval, drainage and engineering considerations.

Stopping Running Grasses Getting Into Beds

The lawn grasses used across most of New South Wales all spread by running. Kikuyu is the most aggressive, sending out surface runners that root wherever they touch soil and underground stems that travel horizontally through the profile. Couch behaves similarly with finer runners, and buffalo spreads by surface runners without the underground component. Any of them will colonise a garden bed given an opportunity, which is what a shallow edge provides. Knowing which grass you have changes how much depth is worth paying for, and most households can identify it from the leaf and the runner.

Depth is the specification that matters and it is rarely discussed at quoting stage. Edging installed with a hundred millimetres or more below the soil surface presents a genuine barrier to underground stems, while an edge pressed into the top of the soil presents almost none. Deeper is better against kikuyu in particular. This is the reason a steel edge properly trenched in outperforms a taller plastic edge sitting on the surface. Ask for the depth in writing, since it is the one number that predicts whether you will be happy in three years. Two products at the same price per metre can perform entirely differently purely because of how deep each is set.

Height above the soil does a different job and both are needed. An upstand of thirty to fifty millimetres above the mulch line stops surface runners simply walking across, and it holds mulch in at the same time. Where the edge sits flush for mowing, that containment has to come from the depth of the bed instead. Combining a flush mowing strip with a deeper barrier below it is the arrangement that solves both problems. Mulch depth behind the edge also contributes, since a deep layer of coarse mulch is harder for a runner to cross than bare soil. Fifty millimetres is generally enough, and much more starts to look like a wall rather than an edge.

No edging is entirely kikuyu proof and it is honest to say so. Runners will eventually climb over any upstand and creep across the top, which is why an edge reduces maintenance rather than eliminating it. What good edging does is turn a constant battle into an occasional trim along a clean line, which takes minutes rather than an afternoon. Ongoing lawn care sits under lawn mowing and garden maintenance.

Where a bed is already invaded, deal with that before the edging goes in. Installing a new edge around a bed full of established kikuyu simply contains the problem inside the bed, where it will continue spreading among your plants. Clearing the runners out properly, including the underground stems, is the necessary first step even though it is tedious. That work sits under garden bed weeding and mulching. Removing runners thoroughly takes patience because every fragment left behind reshoots, and doing it once properly beats doing it repeatedly.

Materials and What Each One Suits

Steel edging has become the default in contemporary gardens and there are good reasons for it. It bends smoothly around curves, presents a very fine line that almost disappears visually, installs to a consistent depth and lasts a long time. Thickness is what separates products, since thin gauge steel buckles under a mower wheel and heavier gauge stays true, so get the thickness stated rather than accepting steel as a description. Expect $45 to $110 a metre installed. Galvanised and powder coated finishes both last well, and the choice between them is largely about whether you want the edge visible or invisible. It also disappears visually once mulch and plants grow in, which suits gardens where the planting rather than the hardscape should be noticed.

Corten and other weathering steels deserve a specific warning that suppliers rarely volunteer. These products develop a stable rust patina which is the whole point aesthetically, and during the first year or two that rust runs off with rain and stains whatever is adjacent. On a bed beside pale concrete, sandstone paving or a light coloured path, that staining is permanent and difficult to remove. Use it against lawn or dark surfaces, not against pale hard surfaces. If you want the look beside a pale surface, allowing the material to weather elsewhere before installation reduces but does not remove the problem.

Timber sleepers give a heavier look and suit informal and rural gardens. Treated pine costs $40 to $90 a metre installed and lasts perhaps ten to fifteen years in ground contact, while hardwood costs $70 to $150 and lasts longer. Both are vulnerable to termites in most of New South Wales, and both will eventually fail at ground level where moisture sits. Where sleepers are being used for anything raised, that shifts category, covered under retaining wall landscaping. Recycled hardwood sleepers are worth asking about, since they weather beautifully and often cost less than new hardwood.

One caution on treated timber matters where food is grown. Older copper chrome arsenate treated timber is not recommended for use around vegetable gardens, and although the treatment products used today differ, many gardeners choose to avoid treated timber entirely in edible beds. Alternatives including hardwood, steel, brick and concrete avoid the question completely. Disposal of treated timber is also regulated and it must never be burnt, with waste requirements administered by the NSW EPA. Lining a treated timber bed with a barrier is sometimes suggested, though choosing a different material avoids the question entirely.

Machine extruded concrete kerbing is laid continuously on site, extruded meaning the machine forms and pushes out the profile as it travels along the line, and it is popular across New South Wales for good reason. It handles curves beautifully, costs $45 to $90 a metre, comes in several profiles and colours, and produces a monolithic edge with no joints for grass to exploit. The trade offs are that it is permanent, it needs vehicle or machine access along the run, and it cannot be adjusted once cured. Colour and profile are chosen from a range at quoting stage, and a sample of the actual finish is worth asking to see rather than working from a brochure. Expansion joints cut at intervals reduce random cracking and are worth confirming are included.

Brick, paver and stone edging suit traditional gardens and older homes. Brick on edge bedded in concrete costs $70 to $160 a metre and gives a mowing strip at the same time, while sandstone at $120 to $350 suits Sydney's Federation and Victorian housing where the material is already part of the streetscape. Both are labour intensive and both look better as they age. Related hard surface work sits under outdoor tiles and paving. Reclaimed brick suits period properties particularly well and is often available from demolition yards at reasonable cost.

Mowing Strips and Why They Are Worth It

A mowing strip is a flush band of hard material between lawn and bed, wide enough that a mower wheel runs along it while the blade cuts the grass right to the edge. That single detail removes the need for whipper snipping along that line entirely, which for most households is the most tedious part of yard maintenance. It is the difference between mowing being a complete job and mowing being followed by another task. It also protects the edging itself, since a mower running on a solid strip never contacts the edge at all. Households who have lived with one rarely go back to a plain edge on their next garden.

Width is what makes it work and it is frequently made too narrow. The strip needs to be wide enough for a mower wheel to sit fully on it without dropping off, which generally means at least the width of a standard brick or paver and preferably more. A narrow decorative band that a wheel cannot track along achieves nothing functional. Measure your mower's wheel spacing before deciding, since that is the dimension that matters. Two hundred millimetres is a practical minimum for most walk behind mowers.

Level is equally important and slightly counterintuitive. The strip should sit flush with or marginally below the surrounding lawn surface, not proud of it, because a raised strip means the mower rides up and scalps the grass beside it. Getting that level right along a whole run takes care during installation and is one of the things that separates a professional result from a weekend attempt. Settlement over the first year can change that relationship, which is an argument for a properly compacted base beneath the strip. Checking it with a straight edge across the strip and the lawn at handover takes a minute.

Brick or paver laid on a concrete haunch is the traditional solution and remains excellent. It combines the mowing strip with the visual edge, it can be repaired a unit at a time, and it suits most house styles. Poured concrete strips are equally effective and cheaper over long runs, particularly where the shape is simple. Machine extruded kerbing can be specified with a flat profile that serves the same purpose. Matching the brick to the house is worth the effort, since a mismatched strip reads as an addition rather than part of the garden.

The economics favour a mowing strip on any lawn you cut yourself. The additional cost over plain edging is real, running perhaps twenty to fifty per cent depending on material, and it is recovered in time rather than money. Where a contractor mows the lawn, the saving appears in their time instead, and it is worth mentioning to them. Lawn establishment and repair sit under lawn renovation and repair. Households with long bed edges gain most, since that is where whipper snipping consumes the most time.

Getting It Straight and Keeping It That Way

Setting out is what determines whether an edge looks right, and it happens before anything is dug. String lines for straight runs, a hose or marking paint laid out for curves, and standing back to look at the shape from the house and the street all belong in the first half hour. Curves that look generous on the ground frequently look mean from a distance, and it is far easier to adjust a hose than a concrete kerb. Photograph the marked out shape from an upstairs window if you have one, since the plan view reveals awkwardness the ground view hides.

The trench is the part that decides performance rather than appearance. It needs to be deep enough for the edging to sit at the specified depth below soil level, straight along its length, and consistent so the edge does not wander up and down. Digging it by hand through clay or rocky ground is slow work, which is why quotes vary so much on apparently identical runs. Ground conditions are worth mentioning when you enquire. A trench that wanders in depth produces an edge that dips and rises, which is visible from a distance even when the line is straight. Soft freshly filled ground also needs compaction before the edge goes in, or the line settles unevenly.

Fixing and support vary by material and are worth understanding. Steel edging uses stakes driven through the profile into the ground at regular intervals, and the stake spacing determines whether it stays straight under load. Timber sleepers are pinned with stakes or reinforcing bar. Brick and paver work sits on a concrete haunch that supports it from behind. Extruded kerbing relies on its own mass and the compacted base beneath it. Corners and tight radii need closer fixing than straight runs, since that is where the material wants to move.

Levels and falls need thinking about where water is involved. A solid continuous edge across a slope acts as a small dam, ponding water on the uphill side and causing the bed to stay wet, so weep points or a deliberate gap allow drainage through. On a path or driveway edge, water should be directed along rather than trapped. Where drainage is already a problem, that sits under drainage. A bed that stays wet against a wall or a fence causes its own problems, so directing water away matters as much as containing mulch.

Finishing determines how it looks on the day and how it performs afterwards. Backfilling both sides properly so no gaps remain, compacting the soil against the edge, topping up mulch to the right depth behind it, and cleaning off any spill on adjacent surfaces are the last steps. On concrete and stone work, cleaning up before material cures matters, because removing dried mortar or concrete from paving afterwards is difficult. Ask for the lawn edge to be trimmed back cleanly at handover, since that is what makes the new edging read as deliberate.

Clay, Tree Roots and Ground Movement

Reactive clay soils across western and south western Sydney and parts of the central west and Riverina move seasonally, swelling when wet and shrinking when dry, and they push garden edging around over time. Rigid materials suffer most, with concrete kerbing cracking and brick edging opening at the joints, while flexible steel and timber tolerate the movement better. Deeper installation helps by reaching below the zone of greatest movement, and it is the reason a shallow edge in clay tends to wander. Movement is greatest at the surface and reduces with depth, which is why a deeper installation stays truer over the years.

Tree roots are the other force that lifts and distorts edging, and they operate on a longer timescale. Roots thicken over years, and an edge run close to an established tree will eventually be pushed out of line regardless of the material. Cutting significant roots to install edging can destabilise the tree and may breach a council tree protection condition, which makes routing the edge around the root zone the sensible approach rather than through it. Flexible materials tolerate slow root movement better than rigid ones, which is worth knowing when planting near an existing edge.

Sandstone and rock near the surface constrain what is possible across a great deal of Sydney. Where rock sits at two or three hundred millimetres, digging a trench deep enough for a proper barrier means breaking through it, which changes the job entirely. In those gardens the practical answer is often a surface laid edge such as brick on a haunch, accepting less depth and relying on maintenance instead. Excavation of that kind sits under excavation. A test hole along the intended line tells you what you are dealing with before anyone commits to a price. Working with the rock rather than against it often produces a better garden than forcing a uniform depth.

Sandy coastal soils behave differently again and bring their own problem. They drain fast, hold edging less firmly, and allow stakes to loosen over time as sand moves around them, so longer stakes and more of them are worth specifying. Salt in coastal air also attacks steel and fixings, which makes galvanised or properly coated products worth the premium anywhere near the ocean. Stainless or heavily galvanised fixings cost little more and remove the most common failure point in beachside gardens.

Slope changes both the design and the function of an edge. On a fall, edging tends to become a series of small steps rather than a continuous line, since a level edge on sloping ground either disappears at one end or stands too proud at the other. Stepping it deliberately looks better than letting it drift, and it also stops soil washing down and over. Where the slope is significant, the answer is usually terracing rather than edging, covered under retaining wall builders.

When Edging Becomes a Retaining Wall

The line between edging and retaining is about what the material is holding back rather than what it is called. An edge sitting between a lawn and a bed at the same level is edging. The same sleeper with three hundred millimetres of soil piled against one side is retaining, and it is subject to the loads that come with holding soil, particularly when that soil is saturated after heavy rain. Owners rarely make this decision consciously, which is how a border becomes a structure over a couple of gardening weekends. A useful test is whether removing the edge would cause soil to slump, since if it would, the edge is doing structural work.

Approval thresholds apply once a retaining structure passes a modest height, and they vary with the property and the situation. Retaining walls above a certain height generally require approval and engineering, and walls close to a boundary or affecting a neighbouring property bring further considerations again. Planning and property information is accessible through Service NSW, and the council can confirm the position for a specific site in a phone call. Boundary situations matter particularly, since a wall affecting a neighbour's land brings obligations beyond your own property. Council duty planners will usually answer a straightforward question about height thresholds over the phone.

Drainage is what makes retaining structures work and it is what fails when they are built as overgrown edging. Water building up behind a wall exerts substantial pressure, which is why proper retaining includes drainage behind the wall and weep points through it. Sleepers pinned into the ground and backfilled with no drainage will lean, then fail, and the failure usually happens during heavy rain when the ground is at its heaviest. Agricultural drain behind the wall discharging to a suitable point is the standard arrangement and it is not expensive to include.

Raised beds sit in the same territory and are worth thinking about honestly. A raised vegetable bed four hundred millimetres high is holding back soil, and while the loads are modest the same principles apply to construction and drainage. Purpose designed raised bed systems handle this properly, and building one from sleepers without corner support tends to bow outward within a couple of seasons. Options are covered under garden bed installation. Corner posts or bracing make a substantial difference to how a timber raised bed holds its shape over time.

Engineering advice is cheap relative to a failed wall and is worth taking where any doubt exists. Where a structure will hold back a metre of soil, sit above a neighbour's property, or support anything above it, that is a design question rather than a landscaping preference. Certification and design for these structures sits under retaining wall engineering and certification. A collapsed retaining wall damages whatever sits above and below it, which is usually worth far more than the design fee would have been.

What Drives the Price

Material choice sets the base rate and the range across materials is the widest variable here. Plastic at the bottom and cut sandstone at the top differ by a factor of ten or more per metre, and within each material there are quality tiers that matter, particularly with steel where gauge determines whether the edge stays straight. Compare the specific product rather than the material name. Mixing materials across a garden is also legitimate, using an inexpensive edge in hidden areas and a better one where it is seen. Sample offcuts are worth asking for on anything expensive, since colour and texture read differently outdoors than in a showroom.

Installation depth drives the labour and it is the thing worth paying for. A surface laid edge goes down quickly, while a properly trenched barrier means excavating the full length of the run to a consistent depth, and that difference is hours rather than minutes on a long run. Ground conditions compound it, since the same trench through soft loam and through clay with rock in it are entirely different propositions. This is the line where a cheaper quote is usually cheaper for a reason rather than through efficiency. Hand digging through clay is genuinely hard work, which is reflected in an honest quote.

Shape affects cost differently depending on the material. Curves are effectively free in steel and extruded concrete, which flex or form to whatever line is set out, and expensive in brick, paver and sleeper where every unit must be cut to follow the arc. Households wanting flowing bed shapes should factor that into the material decision rather than choosing the material first and the shape second. Simplifying a fussy bed shape at the same time often improves both the look and the price.

Access and delivery matter more with heavy materials than light ones. Sandstone, sleepers and pavers all need to reach the work, and a rear garden accessible only through a side gate means every piece is barrowed. Machine extruded kerbing needs the machine itself to reach the line, which rules it out in some enclosed courtyards. Mention your access when you enquire, since it determines what is even possible. Sandstone in particular is heavy enough that delivery placement matters, since moving it twice is a real cost. Confirm where a delivery will be dropped, since a pallet left on a nature strip becomes your problem quickly.

Length works in your favour and short runs work against you. Every job carries travel, setup and a minimum charge, so ten metres of edging costs far more per metre than sixty metres of the same product. Where several beds need doing, having them all done at once is materially cheaper than one at a time. Combining edging with other landscaping in the same visit is cheaper again, covered under landscaping.

Garden Edging Costs Across Sydney

Landscapers and edging specialists work throughout the metropolitan area, and machine extruded kerbing operators cover most of the city, which keeps competition healthy on straightforward work. What differs across Sydney is the ground and the garden style, since rock near the surface limits installation depth in some areas while reactive clay causes movement in others, and the housing stock influences which materials look right. Getting two or three quotes matters here because the depth assumed varies far more than the rate does. Machine kerbing operators generally quote by the metre with a minimum run, which suits larger jobs and penalises very small ones.

Sydney AreaSteel Edging per mNotes
Inner & Eastern Suburbs$60-$130Small runs, poor access
North Shore & Northern Beaches$60-$135Rock, sloping gardens
Western Sydney$45-$100Clay, open access
Hills & North West$50-$110Longer runs
South & Sutherland$50-$115Mixed ground

Sandstone is the material that belongs in a great many Sydney gardens and it shows in what people choose. Federation and Victorian homes across the inner west, the north shore and the eastern suburbs already have sandstone in their walls, paths and kerbs, and matching it in the garden reads correctly in a way that steel does not. It is expensive at $120 to $350 a metre and it is the right answer for those properties. Related stonework sits under stone masonry. Salvaged sandstone from demolition and civil works is sometimes available at a fraction of new cost and suits period gardens even better. Split face and sawn finishes read quite differently, and the choice should follow the house rather than the fashion.

Western Sydney gardens contend with reactive clay more than any other factor, and it should influence material choice. Rigid continuous materials crack as the ground moves seasonally, while steel and timber flex and settle. Where concrete kerbing is preferred for its finish, installing it on a well compacted base and accepting that hairline cracking may appear is the realistic expectation. Kikuyu is also dominant in these lawns, which makes installation depth genuinely important. Watering patterns influence the movement as well, so an irrigated bed beside a dry lawn sees more differential movement than a uniformly maintained garden.

Garden Edging Costs in Regional NSW

Materials are easy to source through Newcastle, the Hunter, the Central Coast and the Illawarra, landscapers are plentiful, machine kerbing operators cover the larger centres, and rates barely differ from the city. Further out the labour rate eases while material freight rises, and specialist services such as extruded kerbing may not operate at all, which narrows the practical choices to what a general landscaper can install. Ask whether material freight is included in the quoted rate, since it is sometimes added separately outside the main centres. Combining edging with other garden work in one visit spreads the travel across the whole job.

Regional AreaSteel Edging per mNotes
Newcastle & Hunter$45-$100Good supply
Central Coast$50-$110Sandy and clay soils
Wollongong & Illawarra$50-$110Sloping gardens
Regional cities$45-$105Freight on materials
Rural & remote$55-$130Travel and long runs

Rural gardens use different materials and at a different scale. Long runs of timber sleeper, recycled hardwood, rock salvaged from the property and even railway iron all appear in country gardens, and the aesthetic accommodates a rougher finish than a suburban front yard does. Cost per metre falls as runs lengthen, and using material already on the property removes the supply cost entirely, which is a genuine advantage of a rural block. Long straight runs also suit machinery, which is not an option in most suburban backyards, and larger projects frequently roll into backyard landscaping as a whole.

Grass pressure differs by region and it should influence depth. Kikuyu dominates lawns through the coast and the tablelands and is the most invasive of the common grasses, while couch is more prevalent inland and buffalo through coastal suburbs. Paspalum and other pasture grasses on rural blocks bring their own vigour. The stronger the running grass, the more the installation depth earns its money, and identification information is published by NSW Department of Primary Industries. Paddock grasses invading a homestead garden are a different order of problem from a suburban lawn creeping into a bed. Where a paddock adjoins the garden, a deeper edge plus a maintained mown strip beyond it works better than edging alone.

Termites are a greater consideration on rural and semi rural properties where timber edging is common. Sleepers in ground contact give termites a moisture rich timber source close to the house, and running timber edging up against a dwelling is worth avoiding for that reason alone. Steel, stone and concrete remove the question entirely near a building, which is why they are worth the premium in that specific location even where timber is used elsewhere. An inspection regime for the house is worth having regardless, and timber in the garden is one more reason for it.

What to Look Out For

Ask how deep the edging will sit below the soil, because that number determines whether it works. Anything installed on the surface or pressed shallowly into soft ground will have kikuyu or couch through it within a season, regardless of how it looks on the day. A hundred millimetres or more below soil level is the figure worth asking about, and a contractor who has not considered it is quoting a decorative line rather than a barrier. Get it stated as a measurement rather than a description, since deep is not a specification, and the same applies to any garden bed installation quoted alongside it. A contractor confident in their method states the figure immediately rather than reaching for a general reassurance.

Check what gauge or thickness is being quoted in steel. Thin steel edging is a genuinely different product from heavier gauge and it buckles under a mower wheel, bends when someone stands on it and waves along its length within a couple of years. The price difference reflects real material difference. Ask for the thickness in writing rather than accepting steel edging as a specification. Product data sheets are readily available online and worth two minutes of reading before agreeing. Thicker material also holds a curve more smoothly, which shows on flowing bed shapes.

Be careful with weathering steel next to pale surfaces. Corten and similar products are designed to rust and that rust runs with every shower during the first year or two, staining adjacent concrete, sandstone paving and light coloured paths permanently. It is a superb material against lawn and dark surfaces and the wrong choice beside a pale path. Suppliers rarely mention this and it is not reversible.

Know when you have moved from edging into retaining. Sleepers holding back three hundred millimetres of soil are a retaining structure, not a border, and above a certain height that brings approval and engineering into the picture along with a real need for drainage behind it. Structures built as overgrown edging fail during heavy rain when the soil is heaviest, which is exactly when the consequences are worst. Where you are unsure, describing the height and what sits behind it to the council gets a clear answer quickly.

Confirm licensing and terms for anything beyond a small job. Residential building work above the prescribed value must be carried out by an appropriately licensed contractor under a written contract in New South Wales, and a substantial landscaping project with retaining elements can reach that threshold. Licences can be checked with NSW Fair Trading, and the guarantee that work be performed with due care and skill sits with the ACCC. Written quotes with a scope, a price and a timeframe protect both parties and are standard practice among established contractors.

What to Look for in a Quote in NSW

An edging quote tells you something when it states the depth and the product rather than a rate per metre. It should name the material and its thickness or dimensions, state how deep the edging sits below soil level, describe how it is fixed and at what spacing, confirm whether the run includes a mowing strip, say whether removal of existing edging is included, and note how curves and levels are being handled. Installation depth and steel gauge are the two details most often absent. The finished shape belongs in there as well, since a quote by the metre says nothing about the line the edge will follow. Exclusions are worth reading as closely as inclusions, particularly around removal of existing edging and disposal.

Measure your run and mark the shape before contacting anyone. A hose laid along the intended line gives you the true length rather than a guess, lets you look at the shape from the house and the street, and shows every contractor the same thing. Note the ground conditions as best you can, mention the grass you have, and describe the access route material will take. Photographs of the marked line taken from a few positions help contractors quote without attending twice. Include the total length in your first message, since it is the number every contractor asks for.

A contractor who asks about your grass is thinking about whether the edge will work. Someone who asks what the soil is like, checks whether rock is likely, asks whether you mow yourself and mentions installation depth without prompting has installed edging that lasted. Quoting from a length alone means easy digging and surface installation have been assumed, which is the quote that looks cheapest and performs worst. Ask what depth they normally install to and why, since the answer reveals whether they have a method or a habit.

Settle the depth, the product, the shape and the strip before work starts. Confirm in writing how deep the edging sits and what thickness or dimension the material is, mark the final shape on the ground and look at it before anything is dug, decide whether a mowing strip is included, and agree what happens to any existing edging. Then top up the mulch behind it properly. Related services are gathered under landscaping, with bed preparation under mulching.

Garden Edging FAQs - NSW 2026

How much does garden edging cost in NSW?
Plastic edging runs $15 to $35 a metre installed, steel $45 to $110, timber sleepers $40 to $150 depending on species, machine extruded concrete kerbing $45 to $90, brick or paver on edge $70 to $160 and sandstone $120 to $350. Removing existing edging adds $10 to $25 a metre, with concrete at the top of that range. Those figures assume reasonable soil and access, both of which vary enough to move a quote considerably. Length works strongly in your favour, since every job carries travel, setup and a minimum charge, so ten metres costs far more per metre than sixty metres of the same product. Where several beds need doing, having them all done at once is materially cheaper than one at a time.
Why does grass keep growing through my edging?
Because the edging is not deep enough. The lawn grasses used across most of NSW spread by running rather than only by seed: kikuyu is the most aggressive, sending out surface runners that root wherever they touch soil plus underground stems that travel horizontally through the profile, couch behaves similarly with finer runners, and buffalo spreads by surface runners. Edging installed with a hundred millimetres or more below the soil surface presents a genuine barrier to those underground stems, while an edge pressed into the top of the soil presents almost none. This is why a steel edge properly trenched in outperforms a taller plastic edge sitting on the surface. Height above the soil does a different job, with an upstand of thirty to fifty millimetres stopping surface runners walking across. No edging is entirely kikuyu proof, but good edging turns a constant battle into an occasional trim.
What is a mowing strip and is it worth the extra?
A mowing strip is a flush band of hard material between lawn and bed, wide enough that a mower wheel runs along it while the blade cuts the grass right to the edge, which removes the need for whipper snipping along that line entirely. For most households that is the most tedious part of yard maintenance, so it is the difference between mowing being a complete job and mowing being followed by another task. Width is what makes it work and it is frequently made too narrow, since the wheel must sit fully on it without dropping off, generally meaning at least the width of a standard brick and preferably more. Level matters too: the strip should sit flush with or marginally below the lawn, because a raised strip means the mower rides up and scalps the grass beside it. The extra cost runs perhaps twenty to fifty per cent.
Is Corten steel edging a good idea?
It depends entirely on what it sits next to, and this is the warning suppliers rarely volunteer. Corten and other weathering steels develop a stable rust patina, which is the whole point aesthetically, and during the first year or two that rust runs off with every shower and stains whatever is adjacent. On a bed beside pale concrete, sandstone paving or a light coloured path, that staining is permanent and very difficult to remove. It is a superb material against lawn or dark surfaces and the wrong choice beside pale hard surfaces. Separately, with any steel edging, get the gauge or thickness stated rather than accepting steel as a description, because thin steel buckles under a mower wheel, bends when someone stands on it and waves along its length within a couple of years, while heavier gauge stays true.
What is machine extruded concrete kerbing?
It is a continuous concrete edge formed on site by a machine that extrudes the profile as it travels along the line, and it is popular across NSW for good reason. It handles curves beautifully at no additional cost, runs $45 to $90 a metre, comes in several profiles and colours, and produces a monolithic edge with no joints for grass to exploit. The trade offs are that it is permanent and cannot be adjusted once cured, and the machine itself needs access along the whole run, which rules it out in enclosed courtyards and some rear gardens. It can also be specified with a flat profile that doubles as a mowing strip. In reactive clay areas, expect that hairline cracking may appear over time as the ground moves seasonally, which is a characteristic of rigid continuous materials rather than a defect in the installation.
Can I use treated pine sleepers around a vegetable garden?
Many gardeners choose not to. Older copper chrome arsenate treated timber is not recommended for use around vegetable gardens, and although the treatment products used today differ, plenty of people avoid treated timber entirely in edible beds rather than weigh the question. Alternatives including hardwood, steel, brick and concrete avoid it completely and are worth considering where food is grown. Treated timber also has disposal requirements, and it must never be burnt, with waste rules administered by the NSW EPA. For ornamental beds, treated pine costs $40 to $90 a metre installed and lasts perhaps ten to fifteen years in ground contact, while hardwood costs $70 to $150 and lasts longer. Both are vulnerable to termites in most of NSW, and running timber edging up against a dwelling is worth avoiding since it gives termites a moisture rich timber source close to the house.
When does edging become a retaining wall?
When it is holding back soil rather than simply dividing two areas at the same level. A sleeper with three hundred millimetres of soil piled against one side is retaining, and it is subject to the loads that come with holding soil, particularly when saturated after heavy rain. Approval thresholds apply once a retaining structure passes a modest height and vary with the property and situation, with walls close to a boundary or affecting a neighbouring property bringing further considerations. Drainage is what makes retaining work and what fails when structures are built as overgrown edging, since water building up behind exerts substantial pressure, which is why proper retaining includes drainage behind the wall and weep points through it. Sleepers pinned in and backfilled with no drainage lean and then fail, usually during heavy rain when the ground is heaviest and the consequences worst.
My soil is heavy clay. Which edging suits?
Flexible materials, generally. Reactive clay across western and south western Sydney and parts of the central west and Riverina moves seasonally, swelling when wet and shrinking when dry, and it pushes garden edging around over time. Rigid materials suffer most, with concrete kerbing cracking and brick edging opening at the joints, while steel and timber flex and settle with the movement. Deeper installation helps by reaching below the zone of greatest movement, which is one more reason depth matters. Where concrete kerbing is preferred for its finish, installing it on a well compacted base and accepting that hairline cracking may appear is the realistic expectation rather than a reason to avoid it. Kikuyu is also dominant in western Sydney lawns, which makes installation depth genuinely important for function as well as stability.
What if there is rock or tree roots along the line?
Both constrain what is possible and both are common. Sandstone near the surface affects a great deal of Sydney, and where rock sits at two or three hundred millimetres, digging a trench deep enough for a proper barrier means breaking through it, which changes the job entirely. In those gardens the practical answer is often a surface laid edge such as brick on a concrete haunch, accepting less depth and relying on maintenance instead. Tree roots operate on a longer timescale, thickening over years so that an edge run close to an established tree is eventually pushed out of line regardless of material. Cutting significant roots to install edging can destabilise the tree and may breach a council tree protection condition, which makes routing the edge around the root zone the sensible approach rather than digging through it.
Should I clear the bed before edging goes in?
Yes, particularly where grass has already invaded. Installing a new edge around a bed full of established kikuyu simply contains the problem inside the bed, where the runners continue spreading among your plants with a tidy border around them. Clearing the runners out properly, including the underground stems, is the necessary first step even though it is tedious, and doing it afterwards is harder because the edge is in the way. Setting out is the other thing to do before anything is dug: string lines for straight runs, a hose or marking paint laid out for curves, and standing back to look at the shape from the house and the street. Curves that look generous on the ground frequently look mean from a distance, and adjusting a hose is far easier than adjusting a concrete kerb. Then top up the mulch behind the finished edge.
