When discovering Japanese knotweed on your property it’s important to make yourself aware of the legal considerations. The presence of this invasive plant can potentially affect property values and hinder development plans, making it essential to act fast.

Under the Wildlife and Countryside Act 1981, it is an offence to cause or allow Japanese Knotweed to spread into the wild. The Environmental Protection Act 1990 categorises Japanese knotweed as ‘controlled waste’ meaning it must be disposed of correctly at licensed landfill sites. 

Non-compliance with these regulations can lead to fines or legal consequences. It is essential to familiarise yourself with the legal obligations and consult with Japanese Knotweed Removal Specialists such as ourselves to ensure compliance and proper management of Knotweed on your property.

Treat Japanese Knotweed

If you discover Japanese Knotweed on your property, treatment options are available to address the issue. Two common Japanese knotweed control methods are herbicide treatment and stem injection. 

Herbicide treatment involves applying specialised herbicides to the foliage of the plants, which are then absorbed and transported to the root system. This inhibits the growth of the plant and eventually leads to its management. 

Stem injection, on the other hand, directly injects herbicides into the stems of individual Japanese Knotweed plants. This targeted approach delivers the herbicide directly to the root system, preventing regrowth. These treatment methods are effective solutions, especially for smaller infestations, and can help you successfully tackle the presence of Japanese Knotweed on your property.

Long Term Management

Succesfulying controlling Japanese Knotweed requires a long-term management plan. Once the initial Japanese Knotweed Removal is complete, it’s important to regularly monitor the plant to prevent re-infestation. 

Japanese Knotweed has resilient rhizomes that can lay dormant in the soil for several years, making reinfestation a possibility if not addressed properly. By having our Knotweed Removal Specialists regularly inspect the site with our Insurance Backed Guarantee Policy, we can detect any signs of regrowth at an early stage, allowing for swift intervention.

Property Considerations

If you discover Japanese Knotweed on your property, it’s essential to assess the potential impact it may have. We would recommend informing your insurance company about its presence as it can affect your property’s value and insurability.

If Japanese Knotweed has not been previously identified on the property, it is possible to obtain indemnity insurance as a precautionary measure. This type of insurance offers protection against potential future infestations of the plant. 

It can cover the expenses associated with engaging a Japanese Knotweed Removal Specialist to conduct a thorough survey of the property and provide necessary treatment if Japanese Knotweed is discovered. 

Preventative Measures

Implementing preventative measures is crucial in controlling Japanese Knotweed and minimising its spread. One important step is to raise awareness about the plant and its identification among homeowners and landowners. By learning to identify and reporting Japanese knotweed to local authorities and knotweed removal specialists, you can contribute to early detection and prevention efforts. 

Considering an insurance-backed guarantee is highly beneficial when removing Japanese Knotweed from your property. Our insurance-backed guarantee policy at Knotweed Specialists UK provides coverage for the cost of ongoing treatments required to remove Japanese Knotweed, offering financial protection and peace of mind in case of long-term management requirements.
