How to dispose of Japanese knotweed

Japanese knotweed is a highly invasive plant that grows quickly and can cause significant damage to buildings, roads, and other types of infrastructure that stand in its way.

If you've discovered Japanese knotweed on your property, you're probably eager to get rid of it as soon as possible - but don't be too hasty!

It's extremely important to take care when disposing of Japanese knotweed. Under UK law, those who help the plant to spread - even accidentally - may face:

  • Up to 2 years in prison
  • Or a fine of up to £5,000

It's all too easy for Japanese knotweed to spread!

Japanese knotweed didn't become such a widespread problem in this country by pure coincidence. The plant's rhizome root system allows it to spread from one location to another with frightening ease - a single small root fragment can quickly grow into a whole new plant!

This is why you simply can't be too careful when disposing of Japanese knotweed. Failure to follow the law can end up fostering further knotweed growth, and frankly, this species is doing just fine for itself without any extra assistance from us.

So what's the right way to dispose of Japanese knotweed?

While it's not illegal to dispose of Japanese knotweed yourself (as long as you know exactly what you're doing), it's usually preferable to hire a contractor who knows how to dispose of Japanese knotweed properly.

Broadly speaking, there are two ways to deal with Japanese knotweed, both of which are generally better left to the experts:

  1. Excavation - The Japanese knotweed is dug up using heavy earth-moving machinery, then transported to a specialist landfill site with the relevant environmental permit (taking care at all times not let any contaminated soil or plant matter find its way into the wild).

  2. Herbicide - Over a number of months, the Japanese knotweed is repeatedly sprayed with herbicide to control the plant's growth.

Although there are certain situations where option 1 may be preferable (e.g. if there is a tight deadline for clearing the site of Japanese knotweed), herbicide application is by far the cheaper option and is usually sufficient to prevent Japanese knotweed from causing any long-term problems.

How does Japanese Knotweed Spread?

Japanese knotweed has a reputation for being incredibly persistent. It tends to find a way around most conventional methods of weed control, so special care has to be taken to control or remove it properly before it spreads. Any movement of the Japanese knotweed rhizomes, even tiny fractions in the soil, can lead to it spreading. So how does Japanese knotweed spread? Does it spread in more than one way? And what can you do to prevent the spread?

It commonly spreads if:

  • You use infested top soil on your lawn
  • You allow contaminated vehicles onto your property
  • You leave early signs untreated

Scientific research has shown that as little as 0.7 grams of Japanese knotweed rhizome can be enough to create a new plant, that's why preventing Japanese knotweed from spreading is so hard! Here are a few ways you can prevent Japanese knotweed from spreading, follow these steps to help control the spread of Japanese knotweed. 


  • Always buy your top soil from a reputable supplier
  • Brush or jet wash contaminated vehicles before leaving an infested area
  • Treat early signs of Japanese knotweed right away!

Japanese knotweed - the term that strikes fear into many home and business owners nationwide.

However, homes aren't the only buildings and structures that can feel the effects of Japanese knotweed, businesses can too. That's why it is extremely important for business owners to understand how this pesky plant can impact their premises.

Luckily, it's not all doom and gloom - there are still options available. At Taylor Weed Control, we're experts in commercial weed removal and particularly handy when it comes to commercial Japanese knotweed removal.

commercial knotweed removal


Commercial Knotweed Removal Procedures

If you are planning to build or develop on commercial land that contains Japanese knotweed, the choice of a 5-year management plan via herbicides is unfortunately not an option. This is usually a result of time constraints from construction workers, planners, resources and finances.

Where there are plans for development, The Environment Agency advises that for the complete eradication of Japanese knotweed, the entire rhizome needs to be removed from the soil. Especially when the ground is likely to be disturbed and moved during the construction, building and extension of commercial premises, as the spreading of rhizomes is extremely sensitive. That's why it's important you find an effective Japanese knotweed removal service that does a thorough job, quickly. 

How Can We Help?

Taylor Weed Control is committed to assisting all business owners with their commercial knotweed removal requirements. As a result, we provide all our commercial knotweed clients with professional services which are bespoke to their individual needs.

From the initial point of contact, we will provide a thorough and detailed process which will include an initial assessment of your commercial premises, future plans for development, time scales, the identification of potential applications that have to be submitted. Finally, we'll talk you through the different cost-effective commercial Japanese knotweed options.

The Process:

  1. Identification of Japanese knotweed 
  2. Commercial weed removal survey
  3. Report & quotation 
  4. Management plan 
  5. Completion 

Here at Taylor Weed Control, we know how important it is that your commercial Japanese knotweed removal service is completely effective. That's why we offer insurance backed guarantees on our treatments! This gives commercial Japanese knotweed removal customers an additional layer of security so they can continue with their development plans, knowing that the Japanese knotweed won't return.

If you're a homeowner or an individual that has recently bought a piece of land or maybe you're planning on buying some land to build on, it's important for you to be aware of the laws and legalities surrounding planning permission and everybody's favourite beast from the east, Japanese knotweed! 

As Japanese knotweed is classed as an intrusive plant here in the UK, there are a number of laws that surround the eastern Asian plant which may impact on your ability to extend your house or build one altogether. To make things a little clearer, let's take a look at some of these laws and what impact that may or may not have on your chances of gaining planning permission.

Japanese knotweed and planning permission


Planning Permission with Japanese Knotweed 

For individuals considering planning permission for their property, it is essential that the checks are conducted for the presence of Japanese knotweed. If carried out and there is a suspicion that the plant is present, it is vitally important that a survey is requested by an ecological surveyor. If its presence is then confirmed, a control programme suitable for the site in which the property sits will need to be planned as part of the planning application, which includes the safe removal of the knotweed. Planning conditions to ensure the control programme is performed sufficiently should be imposed.

Planning Conditions 

Planning conditions are imposed on sites where Japanese knotweed is known to be present in order to prevent the spread of the invasive plant, which under the Wildlife and Countryside Act 1981 is an offence. Japanese knotweed is notorious for devaluing sites, as well as causing major structural damage to any buildings which may be developed on contaminated land. A management plan will need to be put into place which contains a number of the following things:

  • The objective of control action 
  • An assessment of control options
  • Criteria for completion 
  • Advice on preventing spread around site 


So, despite all of the hysteria surrounding Japanese knotweed, planning permission is still possible if found near your property! However, a stringent and effective plan to manage it must put into place before work can be carried out. 

If you have reason to believe that Japanese knotweed is present on your premises and require experienced professionals to assess and remove it, then do not hesitate to get in touch with Taylor Total Weed Control today for our expert Japanese knotweed removal services!

Any keen gardeners will have heard about Japanese knotweed supposedly having the ability to break through strong, impermeable materials like concrete. Can Japanese knotweed actually grow through concrete? Well, not exactly...

Japanese knotweed is one of the most relentless plants that will happily invade and spread through your garden, causing lots of damage as it goes. But, it's not strong enough to force its way through solid concrete slabs or walls.

That being said... Japanese knotweed is notorious for finding its way through small cracks and holes making it appear as though it has broken through all kinds of stony surfaces on its own!

The root of the problem:

Like any other plant, Japanese knotweed needs sunlight and water to grow. This means that it will take advantage of any crack or hole big enough to fit a trickle of water or a ray of sunshine down! Japanese knotweed's complex root system will send new shoots out to all of these available places, which is why our problem with this weed is so widespread. 

Getting rid of Japanese knotweed:

Unfortunately, most people's efforts to eradicate the plant themselves do not work, simply because destroying the visible plant will barely impact the complex root system underground. To tackle Japanese knotweed efficiently, you really need an expert team to deal with the weed.

Here at Taylor Weed Control, we have years of experience dealing with Japanese knotweed all over South Wales - so we're sure we can help you! Read more about our Japanese knotweed removal service here:

How Do You Get Rid of Japanese Knotweed

In September 2018, the Independent reported that Japanese knotweed had knocked nearly £20 billion off the value of the UK property market, with an estimated 850,000-900,000 properties affected nationwide.

Why does this particular weed pose such a big problem? Well, Japanese knotweed is exceedingly difficult to get rid of. Not just because the plant's rhizome root system can sometimes burrow a full 2 metres down into the ground, but also because a tiny fragment of those roots can sprout into a whole new stem.

This allows Japanese knotweed (once beloved by UK gardeners for its resemblance to bamboo) to spread to new sites at a truly alarming rate - ironically, many attempts to destroy the weed only end up helping it to take root elsewhere!

We don't recommend trying to remove Japanese knotweed yourself.

Japanese knotweed is recognised by British authorities as a highly invasive non-native plant, and there are certain laws in place to keep it from spreading. For example, Japanese knotweed is classed as 'controlled waste', meaning that it can only be disposed of at specially-licensed landfill sites.

As mentioned above, attempting to eradicate Japanese knotweed by yourself can backfire and make the problem even worse, so it's generally wise to call in a Japanese knotweed removal specialist to assess the situation and determine the best course of action.

Broadly speaking, there are two ways to get rid of Japanese knotweed:

  • Herbicide - Spraying the plant's leaves with herbicide is generally the most cost-effective solution. Herbicide application should take place over several years to ensure the best possible results.

  • Excavation & Disposal - The other option is to use excavation machinery to dig up the affected site, after which the knotweed can be disposed of at one of the aforementioned licensed landfill sites. This is by some distance the more expensive and disruptive approach of the two, but it may be preferable if you're on a deadline.

Ah, Japanese knotweed – the villainous vine of vexation, the botanical ninja of nature, the stealthy samurai of the shrub world!

A thorn in the side of many a property across the UK, this leech of the land has seen numerous properties fall in its wake and countless more fall in value by its mere presence. A devastating addition to any home, this is one problem plant you’re definitely going to want to nip in the bud.

As Sir Francis Bacon once said, “knowledge is power”, so let’s get to work and get acquainted with the knotty pest from the Pacific.

Facts About Japanese Knotweed

In The Art of War, Sun Tzu taught how important it is to “know your enemy”. Sound advice Mr Tzu, sound advice indeed…

Luckily, here at Taylor Weed Control, we’ve got your back on this one with enough factual ammunition to take the fight to your garden plight – and win!

So, prepare to lock and load with these top facts about Japanese knotweed.


Humble origins

A non-native plant from the East, Japanese knotweed was actually brought into Britain as an ornamental plant in the early 19th century. This introduction is commonly attributed to German physician, Philipp Franz Balthasar von Siebold, who was also a traveller and botanist.

While his studies of Japanese flora and fauna brought him national prominence, the invasive species of knotweed he brought with him eventually spread into the wild and has since become part of the British ecosystem, albeit an unwelcome one at that.

Nice one, Siebold…


An impressive spread

As the previous fact may suggest, Japanese knotweed has been known to spread at an impressive rate. In fact, it can sprout up as high as three metres tall in as little as six weeks, towering over you for all to see like the invasive inconvenience it is.

Japanese knotweed is also surprisingly strong and can cause structural problems to a property, roads and drains, particularly if there are existing cracks for it to grow through. Worse still, it has alarming regeneration powers and a tiny rhizome can form a new plant if handled incorrectly.

So, even if you think you have seen the last of this annoying weed, it could quite literally come back to haunt you if not effectively treated.


The family name

Japanese knotweed is part of a collective of flowering plants known as the smartweed family. Now, while that title may give the impression that this plant is highly intelligent, capable of engulfing mankind with its superior intellect and guile, it’s also worth knowing it’s not the only name given to this botanical tribe.

These same “smartweeds” are also commonly known as the Buckwheat family, characterised by simple design, toothless leaves and swollen joints – which immediately seems infinitely less intimidating and far more like a casting call for a Deliverance remake.


A healthy herb?

While most posts about Japanese knotweed will malign the plant as the housing hindrance it is, there are some in the nutritional world that have a wholly different take. Japanese knotweed is actually known to be a source of resveratrol, a plant compound that acts like an antioxidant.

While resveratrol is also present in other accessible foods – including grapes, peanuts and red wine – Japanese knotweed is also deemed an edible source. Not only that, it’s actually considered a delicacy in Japan and can provide several health benefits.

According to, resveratrol found in knotweed may help prevent heart disease, cancer, diabetes and early signs of ageing. However, it’s also noted that it can have a variety of negative effects as well, including drug interactions, so do your homework if you do decide to tuck into your garden guest.


A solvable problem

With all the widespread scaremongering, a Japanese knotweed discovery on your property can understandably strike fear into the hearts of anyone. However, it isn’t the end of the world, so don’t call in the bulldozers just yet. Remember, it’s just a weed – it’s nothing to soil your plants over.

That being said, in order to weed out this horticultural headache from your garden, you’ll need more than a pair of sheers and an appetite for destruction. A topiary trim won’t cut it, so be prepared to dig deep and get your hands dirty.

While it can be a massive inconvenience and prove pricy to get rid of, it is a problem that can more often than not be rectified.


Japanese knotweed treatment

Now that you’re well acquainted with Japanese knotweed, you’re probably wondering what’s the best course of action to take if you have an unwelcome visit from the dreaded plant.

If you catch it early, it can be fairly easy to treat; however, the longer you leave it, the more complex (and costly) it can become – so don’t delay if you spot the knot! Like any ailment, your best bet is to contact an expert for detection, diagnosis and treatment advice.

Luckily, Taylor Weed Control is one of the leading Japanese knotweed specialists in the UK, with over 15 years’ experience fighting this familiar foe. At Taylor Weed Control, we provide honest and transparent advice, “Taylor-made” to help rid you of this pesky plant for good.

how to identify japanese knotweed


Can you spot a lisianthus from a gardenia or tell a rose from a Persian buttercup? If you answered “no” to either of those questions, don’t worry – you’re not alone!

The world of gardening and the great outdoors can be a tad overwhelming for anyone who doesn’t have green fingers or the encyclopaedic knowledge of Alan Titchmarsh.

As such, knowing how to identify Japanese knotweed can be a tough task for an average Joe; however, that’s not to say it’s impossible…


Identifying Japanese Knotweed

Depending on the time of year, Japanese knotweed can sport many different looks. Nevertheless, regardless of its seasonal stylings, no floral fashion statement will change the fact that this Oriental irritant is still a botanical pain in the butt – especially when its within striking distance of your property.

So, how do we spot Japanese knotweed and stop it from worming its way into your home? Let’s find out.


Japanese Knotweed in Spring

During the spring, Japanese knotweed begins to make its presence known. Typically starting in mid-March, red and purple shoots will begin to appear and quickly bear rapidly growing leaves.


Japanese Knotweed in Summer

In the height of the summer, Japanese knotweed is in full swing. Bright and full, it appears green and leafy above ground, boasting creamy-white flowery clusters and purple-speckled stems.


Japanese Knotweed in Autumn

As the lush green of the summer turns to autumnal auburn, Japanese knotweed follows suit. Its leaves will turn a yellowy gold, while the stem will fade to a darker brown.


Japanese Knotweed in Winter

As temperatures drop, the wintertime design of Japanese knotweed becomes far less colourful. Brown and bare, the weed retreats back to its rooty rhizomes, leaving behind its woody stalks.


Plants that look like Japanese knotweed

To add further confusion to the situation, there are a number of other plants that strongly resemble Japanese knotweed. Featuring striking similarities, the list of leafy doubles is frustratingly long and can range from Russian Vine and Himalayan Honeysuckle to bamboo and lilac shrubs.

For more information on Japanese knotweed lookalikes, check out our “Plants That Look Like Japanese Knotweed” blog.

plants that look like japanese knotweed 


If you’re reading this blog, chances are you’re familiar with the horticultural horrors of Japanese knotweed. If this wicked weed wraps its weedy tentacles into your home’s foundation, the results can be devastating for your house and, worse still, catastrophic for your finances.

However, not all suspected cases of Japanese knotweed are actually the real deal. In fact, the villainous vine has many doppelgangers and most instances of suspected knotweed are merely a cases of mistaken identity.

So, before you take a flamethrower to your back garden and bulldoze your house completely, it’s important to know that you are indeed dealing with the legit Nipponese knot and not a floral facsimile.


Plants Commonly Mistaken for Japanese Knotweed

Annoyingly, there are a wide variety of plants that look like Japanese knotweed. As such, identifying Japanese knotweed can be a tough task and a lot more difficult than you may think.

Plants commonly mistaken for Japanese knotweed include:



Baring heart-shaped leaves like its Japanese twin, this also has a rapid growth spurt when it first appears in the springtime.

However, unlike Japanese knotweed, Bindweed isn’t capable of supporting itself and, instead, makes its vertical ascent by coiling itself around the stems of other standing plants.

It also boasts large flowers in the summertime, clearly differentiating itself from traditional Japanese knotweed.


Russian Vine

Much like Japanese knotweed, Russian Vine has similar looking leaves and flowers, while it is also fast-growing.

On the other hand, it is also similar to Bindweed in that it relies on other plants to grow upward, twisting and climbing around the stems of taller, more solid vegetation.



The most widely known of its contemporaries, bamboo grows tall like knotweed and also has visible nodes on its stem, making the two very similar in appearance.

That being said, bamboo stems are considerably more dense than its Asian brethren and boast a strong sturdiness lacking in Japanese knotweed. Bamboo leaves are also notably narrower and longer.


Broadleaf Dock

Part of the same family, Broadleaf Dock shares numerous characteristics with Japanese knotweed, from its arrangement of leaves to the spiky shape of its flowers and stems.

However, this plant is typically shorter than Japanese knotweed and contains a foamy substance in its stem, clearly visible when cracked open.


Other plants that resemble Japanese knotweed include:

  • Ground Elder
  • Himalayan Balsam
  • Himalayan Knotweed
  • Himalayan Honeysuckle
  • Lilac/Woody Shrubs


How to identify Japanese knotweed

So, having met its countless counterfeit counterparts, how do we know when knotweed is not the weed we know?

The answer to that riddle is “with great difficulty”. The real plant itself has a varying appearance depending on the time of year and can be extremely difficult to detect and delineate, particularly during the winter months.

When it comes to identifying Japanese knotweed, many homeowners will head straight to the internet for inspiration. The web can be a great tool to help you spot Japanese knotweed; however, it’s important to remember that this method is far from fool-proof.

As we’ve seen, looks can be deceiving and your worst garden nightmare could actually be nothing to worry about at all. Think of it as the gardening version of self-diagnosing an illness online; while the web can be a great resource, it’s no substitute for a knowledgeable professional.

If you suspect your home is under attack from the pesky plant of the Pacific, your best option is to call in the experts. With over 15 years of experience, Taylor Weed Control is a leading specialist in Japanese knotweed; not only can we accurately separate Japanese knotweed from its lookalikes, we can also treat and remove your unwelcome garden guest accordingly.
