Close up of Japanese Knotweed

The presence of the Japanese Knotweed was not highlighted in house surveys undertaken by the owners of the affected properties, even though the plant was thought to be reaching 8 foot. Unfortunately for the buyers, they were unaware of the adverse effects Japanese Knotweed could cause on their properties and it was only when one homeowner Googled the plant that the severity of the situation became clear.

When the Anti-Social Behaviour, Crime and Policing Act 2014 came into effect, it was only then the local council were able to take action against the property management firm. The firm had various opportunities to take steps to remediate the invasive weed and unfortunately did not take adequate steps to prevent the legal action to be taken against them.

With cases such as Waistell v Network Rail making headlines recently, it has set a precedent for other homeowners who are affected by the troublesome weed that there are cautions in place to ensure encroachment does not occur.

What should you do if you find Japanese Knotweed growing on your property?

New Shoots of Japanese Knotweed

If you are looking to buy or sell a property, you will most likely have heard of Japanese Knotweed. Although it is not illegal to allow Japanese Knotweed growing on your property but it is illegal to allow it to spread – what is your responsibility when it comes to invasive weeds?

Japanese Knotweed is extremely invasive and can cause structural damage if it is left untreated – due to this, most mortgage lenders will not release funds against the property if there is any indication of a growth nearby. If you are looking to sell your property, it may prove useful to ensure you have a management plan in place before putting the property on the market.


DIY methods to remove Japanese Knotweed are not recommended as most mortgage lenders will not accept methods which have not been conducted by a qualified contractor. You may end up paying a lot more than what you need to! Qualified contractors are also able to offer guarantees on their work, which means if the Japanese Knotweed does come back, the property will be protected.

What the Waistell vs Network Rail case means for you…

We have all heard about the landmark Japanese Knotweed case of Mr Waistell v Network Rail, but what exactly was the precedent which was set following the hearing?

Japanese Knotweed was typically used by Network Rail to stabilise railway embankments in the past, and due to this, most railways in Britain are dotted with stands of the invasive weed. Unfortunately for Mr Waistell, his property backed onto one such area. Although there was no Japanese Knotweed growing on Mr Waistell’s property, it was in such close proximity, so as that his solicitors were able to argue that it was interfering with “quiet enjoyment of the property”. This shows us that if there is a premise for Japanese Knotweed to spread onto your property, you have some legal standing.

If you do find yourself in a situation where there is Japanese Knotweed growing within close proximity, we would always advise initially getting in touch with a Japanese Knotweed remediation company as they will be able to come out and conduct a survey for you to get a more detailed insight into the situation at hand.Following the survey, the company should be able to provide you with a management plan to eradicate the Japanese Knotweed. Depending on the extent of the Japanese Knotweed, you may not be prepared to pay for these costs, and this is when getting in touch with a legal professional will come in handy.

Neighbours with Knotweed – a guide to avoid disputes

Your home is your castle.Eradicating Japanese Knotweed in Cheshire

And if you are particularly house proud, you will know that the outside of your home is just as important as the interior. So what should you do when you notice Japanese Knotweed growing in the property next door?

Ideally, you will get in touch with the neighbour initially to see if there is an eradication plan in place. Once you know the status of the offending plant, you should be able to then decide your next steps on how to proceed.

If there is a management plan in place, there’s no need to worry as the neighbours are adequately dealing with the problem. If not, there a few options you can explore:

  1. Arrange for a Japanese Knotweed professional to come out and assess the situation: by doing this you are able to determine as to whether or not the Japanese Knotweed will affect your property directly. They will then be able to advise of any recommendations they may have with regards to your property.
  2. Get in touch with the Environmental Agency: if the Japanese Knotweed has spread over into your garden, your neighbour is liable to pay for the costs of remediation. This is because although it is not illegal to have Japanese Knotweed growing on your property but it is illegal to allow it to spread, and by doing so, your neighbour may be faced with a fine of up to £2,500.00 plus the remediation costs!
  3. Take out your own management plan: with your neighbours permission, it may prove easier to take out a management plan yourself for the remedial work on their property – this would be the best situation if you are looking to sell your property, as many mortgage lenders will refuse to allow funds against a property which has Japanese Knotweed growing within 7m of the boundary. This is obviously a last resort and you may need to decide whether or not the sale of the property is worth the treatment cost.

It is characteristic by its hollow, purple stems and heart-shaped leaves. If you would like to know what Japanese Knotweed looks like in the Winter, carry on reading!

Japanese knotweed displays certain characteristics in the winter to make it more recognisable to the public.  As we move into winter, the leaves of Japanese Knotweed will fall from the plant and the canes will die off. The canes turn brown and have a dark orange centre. The canes stay standing throughout the winter months and can occasionally be seen amongst new stands in the summer.

Japanese Knotweed Image

Summer is finally here, and the sun has started to shine – bliss! You will have noticed that your gardens are flourishing due to the warm weather – but how do you know if you have Japanese Knotweed growing on your property?

Summer is probably one of the easiest times to spot Knotweed. In the early spring you would have seen red or purple shoots appearing through the ground, which would have turned into bamboo-like canes. By now, Japanese Knotweed will be fully grown and therefore easier to spot. The mature stems are hollow and have a distinctive purple speckle, with the leaves growing in a zig-zag pattern.

As we move into late summer, clusters of creamy white flowers will start to appear on the plant. These flowers are nectar rich, so you may identify the presence of Knotweed by noticing more insects in your garden.

If you think you have Japanese Knotweed on your property and need professional advice on identifying Japanese Knotweed, please contact us.
