Invasive plants and tree disease
Bamboo: is it the invasive running kind and how to remove it
Bamboo is not a banned weed, but running varieties spread aggressively by underground stems and can invade neighbouring gardens, leading to disputes. Clumping bamboo stays put and is manageable. Identify which type you have, contain running bamboo with a root barrier, and use a specialist to remove an established running stand.
- Also known as
- running bamboo (Phyllostachys and others), clumping bamboo (Fargesia and others)
- Easily confused with
- Japanese knotweed (early shoots and canes), reeds and tall grasses
- How serious
- Variable: clumping is low risk; uncontained running bamboo can cause real disputes
- Typical cost
- Containment is low cost; full excavation of a running stand is priced by size and access, often substantial
How to identify bamboo
The key distinction is running versus clumping. Running bamboo sends out long horizontal underground stems (rhizomes) that produce new canes well away from the parent plant, so shoots appear across a lawn, through a fence or in a neighbour's garden. Clumping bamboo expands slowly outward in a tight clump and stays roughly where planted.
If new canes are popping up some distance from the main plant, or coming up through paving or under a fence, it is almost certainly a running type. The RHS provides guidance on identifying and controlling invasive bamboo.
How serious is it?
Variable: clumping is low risk; uncontained running bamboo can cause real disputes
Bamboo is not a listed invasive plant like Japanese knotweed and is widely sold for gardens. The problem is specifically running bamboo, which can spread vigorously and has increasingly led to neighbour disputes and legal claims where it crosses a boundary.
Because you can be liable for a running bamboo that encroaches onto neighbouring land, an unconfined running stand near a boundary is the situation to take seriously. Clumping bamboo is generally a low-risk garden plant.
How to fix it yourself
- Identify the type first. If shoots appear well away from the main plant or cross a boundary, treat it as running bamboo and act promptly.
- Contain new plantings with a purpose-made rhizome (root) barrier installed to the correct depth, and keep an eye on the surface for escaping rhizomes.
- Cut off and dig out stray shoots and rhizomes as they appear to stop the spread, repeating regularly.
- For an established running stand, removing it means digging out the dense rhizome mass, which is heavy work, and cut canes and rhizomes can regrow if left.
- Where it crosses a boundary, talk to your neighbour early, as bamboo encroachment can become a legal dispute if ignored.
When to call a professional
- An established running-bamboo stand that needs full rhizome excavation, especially near buildings, drains or a boundary.
- Any situation already involving encroachment onto neighbouring land or a dispute.
Who to call
- A Property Care Association (PCA) invasive-weed or specialist contractor, as many now handle bamboo alongside knotweed.
- A solicitor where bamboo has spread across a boundary and a dispute has arisen.
Indicative cost: Containment is low cost; full excavation of a running stand is priced by size and access, often substantial. Prices vary by area, severity and access, so always get a written quote.
Frequently asked questions
How do I know if my bamboo is the invasive running kind?
Watch where new canes appear. Running bamboo sends up shoots well away from the main plant, through lawns, paving or fences, because it spreads by long underground stems. Clumping bamboo expands slowly in a tight clump and stays put. Stray distant shoots mean it is a running type.
Is bamboo illegal or controlled in the UK?
Bamboo is not a listed invasive plant like Japanese knotweed and is legal to grow and sell. The issue is liability: you can be responsible if running bamboo spreads onto a neighbour's land, which has led to disputes and claims, so containment near boundaries matters.
How do I get rid of running bamboo?
Containment with a deep rhizome barrier and regular removal of stray shoots controls it. Getting rid of an established stand means excavating the dense underground rhizome mass, which is heavy work, and any pieces left behind can regrow, so larger stands often need a specialist.
Can bamboo damage my house or my neighbour's?
Running bamboo can spread under fences and paving and exploit gaps, and crossing a boundary can cause neighbour disputes and legal claims. It is best contained with a root barrier and removed promptly if it starts to encroach, particularly near buildings and boundaries.
