A homeowner ringing us about bamboo almost always opens with the same line: “It just keeps coming back.” That sentence is the running-bamboo tell, and it’s a useful one — because everything that happens next, from the treatment timeline to the cost to the relationship with the neighbour over the back fence, depends on whether the bamboo on your property is running bamboo or clumping bamboo. Most homeowners can’t tell the two apart. This guide walks through the visual signs, the underground biology, and the simple tests you can do in five minutes to know which one you’re dealing with.
Every bamboo plant on earth falls into one of two categories based on how its underground rhizomes grow. Rhizomes are specialised underground stems — they look a bit like long thin roots but they’re actually horizontal stem tissue with the ability to send up new shoots wherever they break the surface.
Running bamboo (botanically, the leptomorph type) sends its rhizomes long distances laterally. A single Phyllostachys plant can extend new rhizomes several metres in a single growing season, and each rhizome stays viable for years. The visible plant might be in one corner of your garden but the underground network can be exploring under your lawn, into your neighbour’s yard, and along the path of least resistance through your soil.
Clumping bamboo (the pachymorph type) keeps its rhizomes close to the parent plant. New rhizomes branch off the existing ones but they curve back toward the cluster rather than running out into the open ground. The clump expands at most a few centimetres per year. It stays where you planted it.
That single difference in rhizome behaviour is the whole story. Every other contrast between running and clumping bamboo — the spread pattern, the removal cost, the chance of crossing onto a neighbour’s property, the chance of structural damage — flows directly from it.
How to identify which one you have — five-minute test
The fastest way to tell what you’ve got is to look at where the new shoots are coming up.
Where are the new shoots? Take a photo of the bamboo from above, then walk around your garden and mark every spot where a new bamboo shoot is poking up. If the new shoots are all within 30cm of the parent clump, it’s clumping bamboo. If you find shoots a metre or more from the parent — under the lawn, along the fence line, in a garden bed on the other side of a path — it’s running.
What does the new shoot look like? Clumping bamboo shoots emerge thick and short, in a tight cluster, with very little vertical distance between them. Running bamboo shoots emerge thin and tall, individually, often metres apart, like soldiers scattered through the garden.
Pull back the mulch. If you can spot a rhizome on or just under the surface, look at its shape. A running bamboo rhizome is a long thin segmented stem, sometimes more than a metre long, that looks like it’s heading somewhere. A clumping bamboo rhizome is a short knobbly stem that branches outward but doesn’t travel.
Check the spacing of the visible canes. In a clumping bamboo, the canes pack close together — sometimes you can barely fit a finger between them. In a running bamboo, the canes stand more loosely, like trees in a sparse forest.
Look at the species, if known. If the bamboo was deliberately planted and you remember the species or have a tag, use this list: Phyllostachys aurea (Golden), Phyllostachys nigra (Black), Phyllostachys edulis (Moso) and most other Phyllostachys species are running. Bambusa textilis (Slender Weaver), Bambusa multiplex (Goldstripe and similar), Bambusa ventricosa (Buddha Belly) are clumping.

Why the running variety is the one that causes problems
The vast majority of bamboo removal calls in Sydney involve running bamboo. There’s a simple reason: clumping bamboo behaves itself. You plant it, it grows in a tight cluster, you can trim it, you can move it, you can let it go for years and it’ll still be in roughly the same patch of garden. Clumping bamboo doesn’t make the phone ring.
Running bamboo is the one that ends up in newspaper stories and neighbour disputes. The rhizome system explores aggressively underground for nutrients and water, and when it finds a soft path of least resistance — under a fence, beside a paving joint, around a pool surround — it follows that path. New shoots pop up wherever the rhizome surfaces. By the time most homeowners notice they have a “spreading” problem, the rhizome network is already much larger than the visible bamboo suggests.
This is also why DIY removal of running bamboo almost always fails. You can cut back the visible plant in an afternoon, but the rhizome network is intact and it has years of stored energy. New shoots emerge from the same rhizomes within weeks, often in places where there was no visible bamboo before. The customer who told us “it just keeps coming back” wasn’t exaggerating — the rhizome is winning.
One of our customers in Pendle Hill described exactly this pattern when we got her call:
“I needed a yucca tree removed at my property in Pendle Hill and I am so glad I called ASET Tree Removal. From the very start, the experience was seamless. I was dealing with Amy and her team, who were incredibly professional, polite, and easy to communicate with.”
Once you know which type of bamboo you have, the removal approach becomes obvious.
Clumping bamboo removal is usually a contained, achievable job. The clump can often be dug out in a single session with hand tools, the rhizomes are short and stay close to the parent, and as long as you take out the visible mass and a clear margin around it, regrowth is rare. Some homeowners even manage clumping bamboo as a deliberate screening plant — installing a root barrier at planting and keeping the clump tidy with annual trimming.
Running bamboo removal is a programme, not a job. The rhizome network has to be killed before the plant can be permanently removed. That’s what the ASET 3-step Bamboo Eradication Programme is built for: kill the rhizomes first with concentrated herbicide injection, dig out the weakened root ball, then maintain treatment over 2–3 growing seasons to catch any rhizome fragment that still has enough energy to send up a shoot. You can read the full programme structure on our ASET Bamboo Eradication Programme page.
If you’ve identified clumping bamboo and you’re happy to have it stay, you may not need professional help at all. If you’ve identified running bamboo and it’s causing you problems — spreading where you don’t want it, cracking paving, coming through from the neighbour — that’s the call we get most days of the week.
Common Sydney bamboo species, in detail
In our experience across Sydney and Western Sydney, the bamboo species we encounter most often are:
Golden Bamboo (Phyllostachys aurea) — Running. Easily the most common bamboo problem in Sydney suburban gardens. Beautiful yellow-tinged canes when mature, sold widely in nurseries 20+ years ago, often planted as a screening hedge before its invasive habit was widely understood. If your bamboo was planted by a previous owner before about 2010, there’s a good chance this is what you have.
Decision flow for running vs clumping bamboo removal approach in Sydney gardens
Black Bamboo (Phyllostachys nigra) — Running. Striking dark canes, sold as an ornamental, spreads aggressively. We’ve seen it cross three-metre garden beds in two seasons.
Moso Bamboo (Phyllostachys edulis) — Running. The tallest and fastest-growing of the Phyllostachys species. Less common in Sydney suburban gardens but occasionally planted on larger blocks. Removal is a substantial undertaking.
Slender Weaver (Bambusa textilis ‘Gracilis’) — Clumping. Popular as a privacy screen, well-behaved, doesn’t run. Our default recommendation when a customer asks us “what bamboo should I plant for a hedge?” — though we still suggest installing a root barrier at planting as cheap insurance.
Buddha Belly (Bambusa ventricosa) — Clumping. Distinctive swollen-internode cane, ornamental, very slow spread.
The list isn’t exhaustive — bamboo nurseries sometimes mislabel species, and hybrid varieties can behave differently from either parent — so even if you can identify your bamboo by name, the visual tests in the section above are more reliable than the species ID.
A note on what to do once you’ve identified
If you’ve identified clumping bamboo and want to keep it: no action needed beyond annual trimming.
If you’ve identified clumping bamboo and want to remove it: a single weekend of digging usually does it, though we’re happy to quote if the clump is large or in an awkward spot.
If you’ve identified running bamboo and want to remove it: this is where the call to a specialist matters. Cutting it back without treating the rhizomes will give you the appearance of removal for a few weeks before the new shoots emerge. The honest path is a multi-month treatment programme. The dishonest path is the cheap operator who’ll happily cut the visible plant and leave town before the rhizome retaliates.
If your bamboo is coming from the neighbour’s side: read what to do when your neighbour’s bamboo is invading your property before you do anything else. The treatment plan depends on whether you can do joint treatment with the neighbour or whether a root barrier is the right alternative.
A customer in Narellan Vale gave us a five-star review last month and her opening line is the kind of feedback we hear often when we get the species identification right at the quote stage:
“Their service was fantastic from the first call to finishing the job. I needed 3 palm trees removed from my yard in Narellan Vale. I called and the customer service was very quick, polite, professional and helpful. I got the quote which was much cheaper than quoted elsewhere.”
