Garden borders keep mulch in, lawn out and beds looking sharp, and rubber edging is one of the easiest types for a Sydney DIYer to install. Pick a material that matches your bed shape, soil and budget, then bed it in firmly so it doesn’t heave or trip anyone.
This guide compares edging materials, covers rubber and recycled rubber options, and shows how to install, price and maintain them. For the wider picture, see our garden maintenance services guide.
Key points
- Flexible rubber edging suits curved beds and DIY installs, while steel and timber suit straight, formal lines.
- Recycled rubber garden edging is a lower-waste choice, but check the supplier’s information on what it is made from.
- A border needs a shallow trench and firm backfill, and kikuyu and buffalo runners can still creep over or under it.
- A pro edging and trimming add-on costs AUD 20–50 per visit (typical 25), including GST (October 2026).
Garden borders: which edging material suits your yard
Each material has trade-offs, so match it to your bed shape, soil and how much mowing you do beside it.
| Material | Best for | Strengths | Watch-outs |
|---|---|---|---|
| Rubber edging | Curved beds, DIY installs | Flexible, easy to cut, mower-friendly. | Can lift in heat if not staked; may fade in strong sun. |
| Steel or aluminium edging | Clean, modern lines | Slim, long-lasting, holds sharp curves. | Sharp edges; needs careful installing. |
| Timber sleepers or pine edging | Raised or rustic beds | Natural look, easy to build. | Rots and attracts termites over time. |
| Brick or paver edging | Mow strips and formal borders | Strong, lets the mower wheel run along it. | Needs a base; best installed by a licensed handyman. |
| Plastic edging | Short-term or budget jobs | Cheap and light. | Brittle in UV and often pops out of the ground. |
| Plants and trench edging | Informal borders | No material needed; soft look. | Needs regular recutting to stay crisp. |
Rubber edging: how it works
Rubber edging comes in rolls or lengths with a built-in lip, so it sits above the soil and holds the line.
- It bends around curves without kinking, so you can follow a garden bed’s shape without cutting lots of joins.
- Most products stay flush with the lawn, so the mower wheel can run along the top without catching.
- Stakes or pegs hold it in place, and joiners connect lengths into a continuous run, as the maker directs.
- It doesn’t rot, so it outlasts untreated pine and suits damp, humid Sydney summers.
- It can heave if the trench is shallow or the soil is loose, so firm the backfill and add extra stakes on slopes.
- Keep whipper snippers and edgers away from the top edge, as the string can chew the rubber.
Rubber garden edging: pros and cons
| Point | Pros | Cons |
|---|---|---|
| Install | Quick, with simple tools and no concrete. | Needs a clean trench for a straight, tidy finish. |
| Look | Low-profile and discreet, available in plain colours. | Not as crisp as steel for formal gardens. |
| Weather | Doesn’t rust, rot or crack easily. | May soften and shift in extreme heat. |
| Weeds | Blocks surface runners from lawn into beds. | Kikuyu can creep under or over the lip. |
| Cost | Often cheaper per metre than steel (indicative — compare prices at your local store). | Cheaper products can fade or stretch. |
Recycled rubber garden edging in Australia
Recycled rubber edging is usually made from reprocessed rubber, often from used tyres, and sold through nurseries and hardware stores such as Bunnings.
- Ask the supplier what the product is made from and whether it is sold for garden use, since recycled content varies.
- Check that the edging has UV stabilisers, because untreated rubber can crack or fade after a few Sydney summers.
- Keep it away from edible garden beds if you’re unsure about the product, and ask the supplier about food-garden use.
- Choose thick, flexible lengths with a built-in lip, which hold their shape better than thin strips.
- Buy extra joiners and stakes with your first order, so you don’t have to hunt for matching parts later.
- Recycle offcuts and old edging through your council’s recycling guidance rather than dumping them in green waste.
Eco garden edging options
If you want a lower-waste border, you have more choices than rubber alone.
- Use recycled rubber edging when you want a flexible border and a second life for waste material.
- Choose reclaimed bricks or pavers for a durable border, and book a licensed handyman for any laying work.
- Reuse salvaged hardwood sleepers for raised beds, and keep them above bare soil where possible to slow rot.
- Plant a low, dense border of native groundcovers instead of hard edging that stay neat with little upkeep.
- Cut a clean V-shaped trench between lawn and bed, the simplest zero-material option, and recut it each season.
- Mulch the bed surface to keep soil in, so even a simple border stays tidy.
How to install garden borders step by step
- Mark the line with a hose or string, and step back to check the curve from the house and the street.
- Phone Dial Before You Dig if you will dig deeper than a shallow trench near services or irrigation lines.
- Cut a trench along the line with a half-moon edger or spade, about a hand’s width deep (indicative — check the product instructions).
- Remove runners and roots from the trench, especially kikuyu, couch and buffalo stolons.
- Place the edging in the trench, keeping the lip at the height the maker recommends, and join lengths neatly.
- Drive in stakes or pegs at the spacing the maker directs, and add extra stakes on slopes and tight curves.
- Backfill with soil, firm it down with your boot, then top-dress the bed with mulch.
- Run powered edgers and trimmers only within permitted hours, so the noise isn’t heard inside a neighbour’s home before 7 am or after 8 pm on weekdays and Saturdays, or before 8 am on Sundays and public holidays.
Garden borders and boarders: what people mean
People search for both spellings, but the product is the same: a divider between lawn, bed and path.
- “Garden boarders” is a common misspelling of garden borders, and the same edging products apply.
- Edge a lawn border to stop runners moving into garden beds and to cut back mowing time.
- Use a path border to separate gravel, mulch or pavers from lawn so materials don’t mix.
- Use a raised bed border to hold soil and make a clear boundary around vegetable patches.
- Choose a tree ring border to protect trunks from mower and trimmer damage.
- Pick a front-yard border that suits your house style, using the same material along the whole frontage.
Garden borders cost and upkeep in Sydney

| Garden clean-up, full day | $320 | $520 | $805 |
Common mistakes to avoid
- Skipping the trench and laying edging on top of the soil, which lets it lift as soon as the ground dries.
- Leaving kikuyu or couch runners in the soil, so the lawn pushes straight through your new border.
- Using too few stakes on curves and slopes, which causes waves and gaps within the first summer.
- Setting the lip too high, which catches mower wheels and becomes a trip hazard for visitors.
- Cutting through irrigation lines or cables because you didn’t check before digging.
- Running an edger early on a Sunday, which can break the noise rules and annoy neighbours.
FAQ: rubber edging and garden borders
Is rubber garden edging any good?
Yes, for most curved beds. Rubber edging is flexible, doesn’t rot and lets the mower run along it. It needs a proper trench and enough stakes to stay put, and runners like kikuyu can still push over the lip unless you cut them back each season.
Is recycled rubber garden edging safe for gardens?
Products vary, so read the supplier’s information and ask whether it is sold for garden use. If you plan to grow edibles beside it, ask the supplier before you buy. Check the label or datasheet rather than assuming recycled products are all the same.
What is the cheapest eco garden edging?
A cut trench between lawn and bed is the cheapest, since it needs no materials, but it needs recutting every season. Reclaimed bricks or recycled rubber cost more upfront and last longer, so choose based on how often you want to edge.
Can I install garden borders myself?
Yes, flexible rubber or steel edging is a manageable weekend job with a spade and a rubber mallet. For brick, paver or sleeper borders, book a licensed handyman, especially if the border supports soil or sits near boundaries.
