Japanese Knotweed is a notorious invasive plant that can cause significant damage to properties and biodiversity in the UK. If you spot Japanese knotweed in your neighbour’s garden, it can be stressful and cause concern. However, it’s essential to address the situation efficiently and responsibly to prevent its further spread and protect your property. In this article, we’ll discuss what you can do if you find Japanese knotweed in your neighbour’s garden.

Be sure you have identified it correctly.  

Before taking any action, make sure you correctly identify the plant as Japanese Knotweed. It has distinctive features, such as red-speckled stems, shield-shaped leaves, and clusters of small white or cream flowers in late summer. It typically grows in dense, tall thickets. It’s important to be sure before approaching your neighbour and causing any unnecessary panic! 

Communicate with your neighbour.

Open communication is essential in such situations. Politely and calmly approach your neighbour and inform them that you believe they may have Japanese Knotweed in their garden. They might not be aware of its invasive nature or the potential issues it can cause. A friendly conversation can go a long way in resolving the problem amicably. 

Share any helpful information. 

Offer to share information and resources about Japanese Knotweed and its impact on property values and the environment. Your neighbour may be more willing to address the issue if they understand the risks associated with this invasive plant. Offer to provide them with resources and articles that explain its impact. 

Suggest they seek professional help. 

Japanese knotweed is notoriously challenging to eradicate, and often requires professional help. Suggest that your neighbour consult with an invasive plant removal specialist, like Environet, who can assess the situation and develop a treatment plan. Professionals have the knowledge and resources to handle the problem effectively. 

Help them to understand the legal implications. 

Across the UK, Japanese knotweed is considered as controlled waste. It is illegal to allow it to spread into the wild and could leave your neighbour open to civil litigation if gets into adjoining properties. Share this information with your neighbour, emphasising the importance of addressing the issue promptly. 

Keep an eye on your own property. 

Keep a close eye on your own property to ensure that the neighbouring Japanese knotweed does not encroach onto your land. If it does, follow the same steps outlined above and seek professional help if necessary. It’s important to note that if the knotweed lies within 3m of your boundary, you will have a duty to declare it to a buyer when you come to sell your home.  

Be patient and understanding with your neighbour. 

Dealing with Japanese knotweed can be a long and arduous process. Be patient with your neighbour as they work to manage or eliminate the problem. Be sure to offer your support and understanding throughout the process. 

Be sure to document the issue.

It’s a good idea to document the presence of Japanese knotweed on your neighbour’s property with photographs and written descriptions. This documentation may be useful for legal purposes or insurance claims if the plant causes damage to your property. 

Seek legal advice. 

If all else fails, your neighbour is uncooperative, and the Japanese Knotweed poses a significant threat, consider seeking legal advice. In some cases, legal action may be necessary to protect your interests and the value of your property. 

In short, spotting Japanese knotweed in your neighbour’s garden can be worrying, but it’s crucial to address the situation responsibly and amicably. Open communication, education, and professional guidance are key to resolving the issue while maintaining a positive relationship with your neighbour. By taking these steps, you can help prevent the further spread of Japanese knotweed, and minimise its overall impact.
