What Time of the Year Does Japanese Knotweed Grow?

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Japanese knotweed is a fast-growing, clump-forming perennial plant with tall and dense stems. By exploiting the small openings in pipes or cracks in barriers such as concrete, the plant causes serious damage & sometimes even breaks apart these structures.

Known for its rapid growth, this invasive plant no wonder leaves homeowners worried for several reasons, including property damage, reduced house prices, and more. It is said to cost taxpayers millions of Pounds per year, and the situation only gets worse as the plant has continued to spread across more properties across the UK.

Japanese knotweed growth cycle

Understanding Japanese knotweed identification and the growth cycle is important to get the right treatment for it. Like most other plants, Japanese knotweed doesn’t grow throughout the year and has a seasonal life cycle that develops through different seasons in response to the varying environmental conditions.

Typically, knotweed is quite tall, up to 3m but may vary in height depending on the season. Besides, it has bamboo-like canes that grow in distinctive and dense clumps and spreads rapidly.

All these features give this invasive plant a distinctive appearance, making Japanese knotweed identification an easy task. However, it can sometimes be confused with plants, like Fallopia baldschuanica, Persicaria microcephala, and Leycesteria formosa.

Japanese knotweed identification and growth pattern in different seasons


April to May is the time when new season knotweed stems generate from the underground rhizome system of the plant, using energy stored within to stimulate rapid growth. Bud-like shoots that are red in colour appear first just a few millimetres high from the ground. With the rise in the weather temperature, the buds erupt and begin to grow as stems. In mature knotweed plants, the rate at which they typically grow is 12-18 cm a day. Emergent stems when 10-20 cm high may look like asparagus spears, but soon develop a distinctive appearance when branches and leaves unfurl.


Japanese knotweed identification is the easiest in summer as it is the peak growing season for the plant. By early summer, the stems of the plant reach full height which is typically 2.5-3 m high in mature plants and sometimes higher than that, especially in giant knotweed. By June to July, knotweed starts growing at the rate of several centimetres a day. The free-standing canes of the plant develop purplish speckling near the base and are covered by a dense canopy of foliage at the sides as well as above the stand. This dense canopy blocks the sunlight and stymies the knotweed growth below.


By late summer and early autumn, you see clusters of tiny cream-coloured flowers on the plant. The growth of knotweed usually slows down during this time of the year. The plant prepares for the winter season ahead by re-absorbing all the essential nutrients back into its underground rhizome system. This turns all the leaves as well as stems yellow and then brown as the parts of the plant above the ground die off.


Winter is the most difficult time of the year for Japanese knotweed identification since the plant dies off and enters the dormant phase during this season. But do not be fooled. Its rhizome system is present beneath the soil, all set to emerge again when spring returns and temperatures rise.

How to Identify the Early Signs of Japanese Knotweed

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Like any kind of plant, Japanese knotweed has early signs of growth that allow you to identify the weed before it grows out of control. Japanese knotweed has been known to grow through walls, concrete and even tarmac, damaging the infrastructure of many homes across the UK. For this reason, it’s vital to identify Japanese knotweed in its early stages.

Here’s how you can stop Japanese knotweed in its tracks by looking out for key signs of growth.

Heart-shaped leaves

One of Japanese knotweed’s most prominent features is the heart-shaped (or shovel-shaped) leaves that dominate the plant. They are a vibrant green and can grow up to 20cm long, so aren’t hard to spot. The leaves will be staggered on the stem rather than clustered, giving them more opportunity to soak up sunlight, but will be curled up and dark in colour when the shoots first emerge.

Red shoots appearing

Once Japanese knotweed starts growing, you should be able to identify new red/purple shoots that are often compared to asparagus. These shoots can grow up to 10ft tall and will quickly develop into dense areas of bamboo-like stems during the spring. If you believe you have Japanese knotweed growing on your property and you attempt to cut these shoots down, you should notice a hollow interior. If the interior is solid, it’s likely the plant isn’t Japanese knotweed.

Buds form in early spring

Japanese knotweed growth occurs mainly between April and October, so you will see the appearance of flower buds from early spring onwards. Japanese knotweed buds are round in shape and tend to bloom between late summer and early autumn. The resulting flowers develop in small clusters and are cream/white in colour, creating thick foliage around the leaves and stems.

Quick growth

As one of the fastest-growing weeds in the UK, it’s been reported that Japanese knotweed has grown up to 10cm a day in the height of summer. If you’ve noticed a plant quickly spreading across your garden and even infiltrating other properties, then chances are you’re dealing with Japanese knotweed. The rapid root growth also increases its external appearance, with the plant reaching heights of up to 3 metres in 6 weeks.

How does Japanese Knotweed spread?

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

What is Japanese knotweed?

Japanese Knotweed, also known as Fallopia Japonica is a weed that has the potential to grow up to 20cm per day, causing devastating environmental problems. Not only this, but it can also ruin houses by destroying the exterior walls that surround the property. This can have devastating impacts on the value of the property and make it hard for buyers to get a mortgage. Japanese Knotweed was first brought into the UK in 1850- before it was known how damaging the plant can be and how rapidly it grows.

How does Japanese Knotweed spread?

It is rare that Japanese Knotweed produces seeds, but it does happen on occasion. You might be left wondering how the weed spreads so rapidly! Instead, Japanese Knotweed spreads through the nodes of green stem – water and soil is the perfect environment for the weed to grow! The dispersal of the rhizome fragments, stems and crowns make it easy for this plant to thrive under the UK’s climate. Despite being a huge problem in the UK, the weed isn’t as invasive in Japan as it propagates in a different manner. Taking the weed out of its natural habitat in 1850 was a big mistake as instead of spreading seeds like in Japan, it has learned to survive and spread through roots, stems and crowns.

Each of these infestive plants in the UK is supported by an underground system filled with stems, crowns and rhizomes which spread and send shoots to the surface. It doesn’t take much for a whole plant to grow like the weed can form a fully grown plant from a single rhizome as small as 10mm. This is why it is so important to dispose of Japanese Knotweed correctly, as it can so easily contaminate the ground by dumping it.

Where does Japanese Knotweed come from?

This weed does not simply just appear from nowhere. If you have spotted Japanese Knotweed on your premises, you can expect to find it in the surrounding areas. Try asking your neighbours if they have it in their garden, or have a look around your property to see if you can spot where the Japanese Knotweed is coming from. If you can not identify Japanese Knotweed nearby, there is a possibility that contaminated soil was dumped on your land, which could have been transferred via foot or on a car.

Can animals spread Japanese Knotweed?

Certain animals are able to spread Japanese Knotweed through their droppings. These animals include sheep, cattle and goats. It is unlikely that rhizome fragments will be the cause of new growth via droppings, however, their droppings could contain stems or canes. These can indeed survive the pass through the animals digestive system and form new growth when positioned back into the soil.

Where in the UK is contaminated?

It is to the point now where there are only a few places that the Japanese Knotweed hasn’t spread. A government-approved scheme has now been put into place to track the spread of the weed. The most contaminated areas are London, Birmingham, Leicester, Nottingham, Sheffield, Bristol, Cardiff, Swansea, Plymouth, Southampton, Brighton, Blackpool, Manchester, Leeds, York, Peterborough, Northampton, Southampton, Brighton and Newcastle.

How fast does Japanese Knotweed spread?

During the summer, Japanese Knotweed has been known to spread as much as 20cm per day. Although we know that it rapidly spreads above the ground, there has been no research conducted on what happens below the ground, yet we know that Japanese Knotweed can and does spread through its roots.

What does a Japanese Knotweed winter look like?

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Japanese knotweed is much easier to identify during the summer months with its large heart-shaped leaves and white bunched flowers. The real question is though, what does Japanese knotweed in the winter look like? Can you remove Japanese Knotweed throughout the winter?

One thing is for certain, Japanese knotweed does not die during the wintertime, so don’t be deceived by its dead-looking leaves and stalks! Japanese knotweed prefers to shy away in the wintertime, getting away from the cold, dampness, frost and snow. The weed is not as visible as it is tucked away beneath the ground, where its rhizome system holds on to all the energy it needs to survive through harsh weather conditions. The visible part of the plant starts to deteriorate over the autumn months, where the leaves start to fall, leaving bare canes behind.

What does a Japanese Knotweed winter look like?

As previously mentioned, what can be seen above ground is sparse, especially if the infestation is small and the weeds can be easily flattened. In summer, Japanese knotweed can grow up to 20cm per day! On the other hand, Japanese knotweed during winter usually will not progress growing unless the conditions are at a higher temperature than usual. Large spaces that contain Japanese Knotweed may however be more easily spotted. Hordes of Japanese knotweed canes can stand even throughout the wind and rain.

An effective way to spot Japanese Knotweed during winter is by looking up close. You will notice stems shaped in a zigzag pattern, growing towards the sky. These canes will have an appearance similar to bamboo in a darker shade- hollow and light. Depending on what time you catch the weed, you may also notice the remains of white flower clusters. It is important to try not to break the plant or stand on the plant when identifying them as you may unknowingly spread it to different locations.

-If you’re unsure how to identify Japanese Knotweed, get the professionals in at CYB

I’ve identified a Japanese Knotweed winter- what do I do?

Whatever the case, do not cut or chop Japanese Knotweed down. Japanese Knotweed is extremely difficult to dispose of and you can get fined for disposing of it incorrectly. Breaking canes of the knotweed risk breaking off a part of the crown attached to the underground rhizome network. This can trigger new growth, yes, but it can also lead to new areas of knotweed appearing in your property if the fragments are not properly handled.

A knotweed rhizome fragment that weighs as little as 0.7g can produce a new plant, which is why it’s so important to call up specialists like CYB as soon as possible. Specialists can remove the Japanese knotweed using methods that ensure they won’t return. In fact, CYB has a 5-year warranty to make sure that you feel confident in using their service.

Japanese knotweed winter in urban areas

Japanese knotweed in urban areas can appear little or not at all during winter, however, these are the areas that are most at harm from the weed. They can stand as a serious environmental problem, destroying local ecosystems and causing erosion near riverbanks. Winter floods can enhance a Japanese knotweed infestation as fragments of the knotweed can get transported via the water to new locations.

Is Japanese Knotweed Poisonous?

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Japanese knotweed is a perennial plant that has advanced across the UK, infiltrating housing foundations and gardens. This weed is known for its ability to spread with speed and can even grow up to 10cm a day. It can be difficult to control and even more difficult to eradicate from your property, which is where Japanese knotweed removal comes in.

Whilst the plant is notorious throughout the country, there are still some unknown characteristics of Japanese knotweed.

Is it poisonous?

Luckily, despite the threat it poses to property, Japanese knotweed is not a poisonous plant. Some people can confuse Japanese knotweed with giant hogweed, which can cause severe burns when exposed to UV rays. A few cases of mild skin irritation have been reported when coming into contact with Japanese knotweed, but the plant poses no real threat to humans.

In fact, Japanese knotweed is edible. The plant can become sweet or savoury, depending on how it’s prepared, and can be eaten both raw and cooked. Harvesting Japanese knotweed for consumption doesn’t pose any risks to the environment, as there is no chance of the plant being over-harvested.

Japanese knotweed also contains Vitamin C and Vitamin A, and has been used for centuries as herbal medicine to cure many ailments. Whilst Japanese knotweed isn’t safe for your home, it is completely safe to touch and consume for both humans and animals.

What other threats does it pose?

Japanese knotweed has been known to grow through concrete and can weave itself into the structural foundations of your property. The plant can damage the foundation by targeting weak spots and growing through them. Some homeowners who have found Japanese knotweed on their property have been refused mortgages, making it difficult for them to sell their homes and move elsewhere.

Not only this, but Japanese knotweed can also threaten native vegetation. As the plant grows rapidly and up to 7ft in height, it blocks out and shades other species of fauna, making it difficult for them to thrive. Japanese knotweed also releases a chemical substance that impedes the growth of nearby plants.

Can Japanese Knotweed be Eradicated?

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Japanese knotweed spreads easily across the UK through the unintentional or deliberate movement of the plant. Thankfully, Japanese knotweed cannot spread through seed dispersion, which makes the removal of this plant easier to complete.

However, this doesn’t stop Japanese knotweed from growing at exceptional speeds and posing a threat to both properties and native vegetation. This development has lead to field trials, research and studies all being conducted to help further understand and control this plant.

Can it be eradicated?

In 2018, Swansea University conducted the world’s largest field trial on Japanese knotweed, by testing all 19 methods used to control and remove this plant. Over a period of three years, researchers found that it’s impossible to fully eradicate Japanese knotweed from the UK, with the current available methods.

However, critics of this study found that researchers had failed to properly test physical methods of removal, which have been proven to be 100% effective if done correctly. By overlooking this method, it’s difficult to state whether Swansea University was correct in their findings and how accurate their claims were.

Whilst Japanese knotweed may be impossible to eradicate from the UK, sustained control and management of the plant are almost more important. Investing in various methods of removal will improve the lives of those affected by Japanese knotweed, instead of focusing on eradicating it completely.

How to get rid of Japanese knotweed from your property

Finding Japanese knotweed on your property is worrisome but can be removed. Whilst the overall eradication of Japanese knotweed is still questionable, there is no reason why the plant can’t be eradicated from your property.

Once you have correctly identified the plant, you can then follow the steps to remove it. Japanese knotweed removal can be done with DIY if the plant growth is minimal and it hasn’t spread into the foundations of your home.

Cut down the canes and remove them from your garden or lawn, then apply a weed killer onto the remaining Japanese knotweed. Wait at least a week before removing the weeds and ensure all roots are pulled out in the process. If you are struggling with this, or have noticed Japanese knotweed returning to your property, get in touch with a specialist Japanese knotweed removal service.

Plants That Look Like Japanese Knotweed

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

The spread of Japanese Knotweed on your land or property can be very damaging. With the plants rapid spreading habits, the time taken to remove it can increase dramatically and be very expensive.

The United Kingdom has a number of other plants that can be confused with Japanese Knotweed. This article by CYB Environmental will list some of the most similar plants to aid you in identifying a real knotweed infection. We are a RICS regulated company that specialise in the removal of Japanese Knotweed. For enquiries and assessments, be sure to contact us, we can help you decide whether or not you have a knotweed infection. That being said, let’s get into plants that look like Japanese Knotweed.

Plants That Look Like Japanese Knotweed

Himalayan Knotweed (Persicaria Wallichii)

When not in bloom, Himalayan Knotweed can look extremely similar to it’s Japanese counterpart due to the similar stems. Not only to the eye, but also to the touch as the stem on both plants is hollow.

Take a close look at the leaves, are they very narrow and half as wide as they are long? With the stem growing to around 1cm in diameter? If so, the plant you’re inspecting is likely to be Himalayan Knotweed. The flowers have a pink hue, rather than the pure white plants on Japanese Knotweed.

Himalayan Balsam (Impatiens Glandulifera)

Similar to Japanese Knotweed, Himalayan Balsam is a rapidly growing plant. It can quickly cover a large area and grow as tall as 2.5 Metres. It also has a hollow stem.

Begin by inspecting the stem, you will see the leaves grow opposite each other, rather than the alternating pattern of Japanese Knotweed. The leaves are also much longer and thinner too, with a pink midrib.

Plants That Look Like Japanese Knotweed

Broad-leaved Dock (Rumex Obtusifolius)

Part of the same family, so hardly surprising that it looks similar to knotweed, Broadleaved Dock has leaves arranged alternately along the stem as well. Its flowers and stems also form spikes just like knotweed.

Stems are fluted and shorter than knotweed plants, growing up to 1m in height. The stems are not completely hollow and contain a foam-like substance when snapped open.

Chameleon Plant (Houttuynia Cordata)

The leaves of a Chameleon plant are why it often gets confused with Japanese knotweed. Both plants have heart-shaped leaves and produce flowers, with both reaching heights of a metre or above.

The big difference between them is the flowers. Japanese knotweed produces clusters of small creamy-white flowers, whilst chameleon plants have slightly larger flowers with easily distinguishable petals.


Lesser Knotweed (Persicaria campanulata)

It’s not only the same that is similar. Lesser knotweed has an almost identical bamboo style hollow stem, with small flower clusters and rising to around the same height.

However, lesser knotweed can be identified by its pink flowers rather than creamy-white, with thin ovate leaves rather than heart-shaped ones. The leaves are the biggest indicator, so check this feature of the plant before you jump to any conclusions.

Ornamental Bistorts (Persicaria amplexicaulis)

Also known as Red Bistorts, this plant has similar leaves and stems to Japanese knotweed, with its stems hollow and separated into nodes. Ornamental Bistorts can be mistaken for Japanese knotweed when not in bloom.

Once flowers start to grow, this is where the plant differs. Ornamental Bistorts are also planted on purpose and don’t grow at alarming rates. You are unlikely to suddenly find Ornamental Bistorts on your property if you haven’t planted it yourself.


Horsetail (Equisetum)

When it’s young, horsetail can be confused with Japanese knotweed. Its growth speed and quantity match that of Japanese knotweed, and its sudden appearance might cause some concern.

However, Horsetail soon loses its knotweed similarities as it matures, developing green stems and its signature brush-like appearance.

Russian Vine (Fallopia baldschuanica)

Russian Vine can be mistakenly identified as Japanese knotweed due to its small cluster of flowers, and its mass of green leaves. Some leaves on Russian Vine’s could also be mistaken as heart-shaped, which might cause confusion for homeowners.

Given its name, the Russian Vine plant is a climber that relies on structures to support itself, unlike Japanese knotweed.


Bindweed (Convolvulus Arvensis)

With Bindweeds heart shaped leaves, it would take a closer inspection to gage whether or not it is Japanese Knotweed. The leaves of Bindweed are also similar to Knotweed due to the alternate growth patterns along the stem. Bindweed can also cover a large area very quickly if left untamed. One of that most mistaken plant that looks like Japanese Knotweed.

As the name suggests, Bindweed is a climbing plant that has the ability to grow by twisting around other erect plants. That being said, it is unable to support its own weight and lacks the ability to grow straight up, unlike Japanese Knotweed. Large pink or white flowers also appear in early summer for Bindweed, also distinguishing it from Knotweed.

Selling A House With Japanese Knotweed

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Selling A House With Japanese Knotweed

Since being introduced to Britain in the early 19th century, Japanese knotweed has spread far and wide across the country, with very few corners of the land remaining unaffected. It has been labelled as an invasive plant by the government and has become enshrined in Japanese knotweed law. Selling a house with Japanese Knotweed has been made difficult due to the requirements of removing the hardy plant, for both neighbours and new tenants.

Selling a house with Japanese Knotweed can be a stringent process, elongating the time it can take to successfully solidify a sale. Utilising our extremely simplified buying process, our clients receive a great deal, along with a fast solution to selling a house with Japanese Knotweed.

Is Selling A House With Japanese Knotweed Legal?

Selling a house with Japanese Knotweed is entirely legal, however, you may need to take some extra measures to ensure that potential buyers feel comfortable purchasing the house and confident that they will be able to secure a mortgage from their bank. This could involve either completely removing the plant from the property, or paying upfront for an insurance-backed treatment plan.

These extra measures can be detrimental when selling a house with Japanese Knotweed. There is a large stigma surrounding selling a house with Japanese Knotweed within the industry, and it is generally frowned upon. The best route to take is utilising a Japanese Knotweed removal service, like our specialists are CYB. We have years of experience removing the weed and irradiating it from properties for good.

Does Selling A House With Japanese Knotweed Cause Devaluation?

Selling a house with Japanese Knotweed can devalue the property between 5-15%, generally speaking. There have been cases where homes have been almost completely devalued as a result of severe infestations, however, these are rare occurrences.

The extent to which a property is devalued will depend on the severity of the infestation and the proximity of the knotweed to the home. This devaluation will usually be equivalent to the cost of removing the plant and restoring the property to its original value. Selling a house with Japanese Knotweed may leave property owners disheartened, but our buying offers remain high, also leaving us to handle the infestation of Japanese Knotweed.

Out Of control Japanese Knotweed Could Land You With a Criminal Record

Out Of control Japanese Knotweed Could Land You With a Criminal Record.

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

At CYB Environment we know everything there is to know about japanese knotweed, we also know how destructive it can be. We have put together this blog to make you aware of the potential dangers of having Japanese knotweed on your property. But first, what is japanese knotweed?

What is Japanese Knotweed?

Japanese knotweed is an invasive species of plant which has bamboo-like stems and has small white flowers. This plant is part of the ‘Dock’ family and is notoriously difficult to get rid of. It is known as the phoenix in the plant world due to the fact that even fire can’t kill it off. It was originally brought to Britain for its beauty and was named the “most interesting ornamental plant of the year” in 1847. In its native homeland this plant is also kept at bay by the climate and also native insects that feed on this plant, whereas the environment in Britain allows it to grow out of control and become aggressive.

How can a plant give you a criminal record?

Japanese knotweed is a troublesome plant with huge destructive roots, they have been known to cause structural damage to many properties. The Home Office issued guidance on Japanese Knotweed in the Anti-Social Behaviour, Crime and Policing Act of 2014. They say a person who has failed to act upon the growth of Japanese Knotweed to the extent that it affects the quality of life of those around it could find themselves being served with a Community Protection Notice.

Failure to then comply with the notice would result in a criminal offence and a large fine (which can be anything up to £2,500 for an individual and £20,000 for an organisation). In Scotland and Ireland, businesses in the local area are already held responsible for making sure Japanese Knotweed doesn’t spread to the local areas as it threatens biodiversity, the economy and human health. Having Japanese knotweed on your property can affect potential house prices, if you are looking to buy or sell.

How do I know if I have Japanese Knotweed?

Large heart shaped green leaves, arranged in a zig-zag across the stem
Red tinged roots and bamboo-like stems
Dense clumps of overgrown plants
Clusters of white flowers around July time, that attract a lot of bees
Brown dead looking stems after it’s died back in September/November time

Did you know that japanese knotweed can grow up to 20cm a day? These plants will take over your garden/property and ensure that plants in your garden will receive less sunlight. Their roots run deep underground, ensuring that they will pop up all around your property. Japanese Knotweed is strong and almost impossible to get rid of without professional help, as it can grow through concrete and tarmac ruining roads, buildings and destabilising river banks.

How do we get rid of it?

If you believe you have identified a growth of Japanese Knotweed at your home or property then don’t hesitate to get in touch with us.

As a homeowner with Japanese Knotweed, you are responsible for ensuring that the plant does not spread into neighbouring land, whether it be privately or publicly owned.

Report Japanese knotweed to your local council if you have noticed that the plant growing unchecked on council land, or if it has spread onto your own property.

japanese knotweed on railways

Japanese Knotweed On Railways

By | CYB Japanese Knotweed Removal & Management Blog | No Comments

Japanese Knotweed is an invasive non-native plant pest and is considered one of the most problematic plant species in the UK and Ireland. The species was introduced to Britain in mid-19th century as an ornamental plant for large gardens, prized due to its imposing size and sprays of creamy white flowers.

Knotweed’s Sinister Nature

You may have seen these plants at railways while waiting for a train or simply passing a station, without realising the devastating effects that Japanese Knotweed has on the environment and on man-made structures. Please see the information under the title “how to identify Japanese Knotweed“, to be able to identify plants in your in area.

Japanese Knotweed thrives in non-restricted areas and out in the open near railways as the plant is not being disturbed and has ample access to sunlight and water. This allows it to spread rapidly and outgrow other plant species. Japanese knotweed has a vast underground rhizome system that can spread and grow rapidly, blocking drains, cracking tarmac and damaging foundations. Action to deal with knotweed may be necessary due to the risk posed to the safe operational railway.

Notifying Japanese Knotweed

If you believe you have identified a growth of Japanese Knotweed at a railway it is important to report it to National Rail or TFL depending on what region of the country you are residing. If the growth is close the boundary walls of the property, you will want to instruct a PCA accredited company such as CYB Environmental for a free site visit. Please note that here at CYB Environmental we provide reports at a fair price to provide evidence of Japanese Knotweed growths.

You may require a report in the incidence that you have reported a Japanese Knotweed growth at the rear boundary of your property to TFL or National Rail and time has passed with no action being taken. A report would provide evidence of this, with relevant photographs and a map stating the growth area of the Japanese Knotweed. We will also provide advice on how best to deal with the growth in the future.

As a homeowner with Japanese Knotweed, you are responsible for ensuring that the plant does not spread into neighbouring land, whether it be privately or publicly owned.

Report Japanese knotweed to your local council if you have noticed that the plant growing unchecked on council land, or if it has spread onto your own property.

For any queries on the above or if you would like a free identification of a potential Japanese Knotweed plant, please contact us at info@cyb-environmental.com
