Bamboo is an attractive plant for your garden. Different species can be ornamental, mask unattractive walls and fences, and provide colour, texture, shade from sunlight and volume to any garden design.
In this article we look at the law around growing and maintaining bamboo in your garden.
Legal status of bamboo in the UK
In the UK, bamboo is not classified as a weed or deemed an invasive species under the Wildlife and Countryside Act 1981.
However, certain species, particularly running varieties, can spread aggressively, causing significant problems if unmanaged. Bamboo generates underground rhizomes (horizontal plant stems that can produce the shoot and root systems of a new plant) that allow plants to encroach quickly into neighbouring gardens if they are not carefully maintained. The rhizomes can also be difficult to remove, because if cut, they can form new plants independently.
If you are thinking of planting bamboo in your garden, you should consider where you plant it and what species you choose so as to prevent disputes with neighbours and significant property damage (either to your home or theirs).
Growing bamboo in a UK garden
Because uncontrolled growth of bamboo can have severe impacts similar to those of invasive non-native species like Japanese knotweed, gardeners should take proactive steps to manage growth.
More commonly, it is running bamboo species (rather than clumping varieties) that cause problems because they can spread rapidly. Choose non-invasive bamboo species where possible.
Avoid planting bamboo near property boundaries, but choose a place with plenty of sunlight.
Installing root barriers can be very effective. For example, you might plant in large pots, or wall in the plant below the soil surface so as to contain the bamboo roots in a specific area.
Barriers should be buried at least 60 cm deep to control bamboo spread effectively. Most bamboo plants need plenty of water frequently, but well drained soil. Root barriers need to be deep, but still allow drainage.
Make sure that you monitor growth throughout the year. Neglect can lead to significant damage to gardens, structures, and ecosystems. Regular maintenance can prevent any issues in the first place. Remove any shoots that sprout outside of your designated area, and make sure that you dig down to pull up the rhizomes.
Encroachment on neighbouring properties
Bamboo encroachment on neighbouring property is a common issue that can lead to serious disputes.
Often, it just causes boundary disputes - that it has become a nuisance in your neighbour's garden.
But it can be more serious.
If the plant damages structures, repairing those can be very expensive, particular if access to them is difficult. For example, bamboo can lift floorboards and tiles, interfere with drains, crack bricks, push through cavity walls, and spring up below patios.
Generally, it is the legal responsibility of the owner of the property on which the bamboo was planted to correct problems.
Managing invasive bamboo
Control measures should be carried out regularly.
Removing bamboo can be complicated. Its not just a case of cutting down the stems that you can see, because invasive types have underground stems as well.
Annual trenching helps manage bamboo by cutting off the rhizomes that extend beyond the planted area. Regular inspection and maintenance of bamboo plants catch and manage any unwanted growth early. However, in certain places, trenching isn't always easy, particularly when the plant grows against a neighbour's wall.
Using weed killer is possible, but it is not guaranteed and can have harmful effects on the soil quality. It can also be poisonous to pets, small children and wildlife in your garden.
Non-chemical methods are more generally recommended for controlling bamboo rather than relying on weedkillers.
Bamboo should not be added to compost bins as it may not decompose sufficiently to eliminate viability. You might find that you spread small quantities of rhizomes where you don't intend.
Legal action for bamboo damage
Neighbour disputes over bamboo are more common than you might think.
When bamboo encroaches from a neighbour's property, you can issue a legal claim for private nuisance. Note that there does not have to be damage to your property - it can just be a nuisance in your garden.
Legal options for unwanted bamboo encroachment and damage include seeking an injunction or claiming damages.
Injunctions can be requested from the court to compel a neighbour to remove their invasive bamboo from your garden or property. You'll need to provide evidence of the bamboo’s origin, such as photographs.
If your neighbour is claiming damages against you for having spread the bamboo, you may need a report that proves it did not originate in your own garden.
If you're the affected neighbour, rather than threatening going to court as a first resort (which is costly), talk to the owner. If talking doesn't result in the outcome you want, then suggest mediation as a less expensive and faster means of dispute resolution. If the neighbour doesn't want to mediate, then seek expert legal advice.
Local council interventions
Local councils can intervene in disputes between neighbours. They can investigate complaints regarding bamboo that impacts neighbours’ enjoyment of their properties. They can also issue abatement notices for bamboo-related issues.
Councils have the authority to issue fines for non-compliance with notices regarding bamboo nuisances. Community Protection Notices can also be issued against neighbours who fail to control bamboo, treating it as antisocial behaviour.
Bamboo removal
If you are removing bamboo from a neighbour's property, make sure that you are thorough, as if you leave any, you'll remain liable for any damage it causes.
For small patches of bamboo plants, manual removal may be fine. Removal costs will just be in your time.
Removing larger clumps and their rhizomes can require heavy machinery. If the plant is growing in a difficult to access area (such as under decking), removal may be expensive.
Consider using a professional removal service if the bamboo infestation is extensive or difficult to manage.
Impact on property value
Unwanted bamboo growth, particularly if it causing structural damage, can significantly reduce a property's value, and complicate sales and mortgages.
Although there is no legal obligation to disclose bamboo presence during property sales (unlike Japanese knotweed), if you are asked about it and lie, you can be held liable by the new owner for removal.
Properties with bamboo on-site may face challenges in being sold, as prospective buyers often shy away from the associated risks.
Outstanding legal disputes over bamboo encroachment can further complicate property sales and further depress market value. Property owners can seek a legal claim for the decrease in property valuations due to bamboo damage.
Summary
In summary, while bamboo plants can add aesthetic appeal to gardens, its invasive nature requires careful management.
Property owners must take proactive steps to manage bamboo growth, prevent encroachment on neighbours' property boundaries, and avoid potential legal disputes.
Common questions and answers
Is bamboo classified as an invasive species under UK law?
Bamboo is not classified as an invasive species under UK law. However, some species can spread quickly and create issues if not properly managed.
What are the legal responsibilities of property owners regarding bamboo spread?
Property owners are legally responsible for preventing bamboo from spreading onto neighbouring properties, as failure to do so could result in liability for any resulting damage.
How can I prevent bamboo from spreading?
To prevent bamboo from spreading into neighbouring properties, install a root barrier to effectively manage its growth. This will contain the bamboo and minimise its invasive tendencies.
What legal actions can I take if my neighbour's bamboo damages my property?
If your neighbour's bamboo damages your property, you can pursue a legal claim for private nuisance, seeking either an injunction to stop further damage or compensation for the losses incurred.
How does bamboo impact property prices?
Bamboo can negatively impact property prices by complicating sales and deterring potential buyers due to associated risks. This can make it harder to sell a property or secure a mortgage.
