Since its likely introduction to Manchester as an ornamental plant in the early 1900s, Japanese knotweed is now indisputably the UK’s most aggressive, destructive and invasive plant according to the Environment Agency. Japanese knotweed can cause damage to property if left untreated and is very difficult to control once established. It is listed under section 14, schedule 9 of the Wildlife and Countryside Act 1981.
Whilst it doesn’t produce viable seeds in the UK, its spread throughout Manchester and Lancashire is mainly a result of human dispersal of the plants' highly reproductive rhizome; the underground stems. The rhizome is resilient, able to grow from small fragments in most conditions and difficult to treat or fully remove. Japanese knotweed is certainly not to be ignored and we are here to help.

The presence of underground Japanese knotweed rhizome on or within 3m of a property will be deemed as affecting the property (Law Society’s TA6 property sellers declaration form).
Additionally, allowing knotweed to spread from a property is deemed as an actionable private nuisance and can lead to legal action.
If you are selling or buying a property in Manchester and suspect the property could be affected by knotweed, we recommend you use our knotweed survey service.
We offer free* Japanese knotweed surveys, that includes categorising risk to property caused by knotweed in accordance to the RICS (Royal Institution of Chartered Surveyors) knotweed risk assessment framework.
After surveying your property or site, we provide you with a Knotweed Management Plan (KMP) document that includes our survey and recommendations and costs for treatment. This could involve herbicide treatment, or complete removal via excavation, both backed by guarantees.
Japanese Knotweed Treatment Manchester
Our Herbicide KMP programmes provide professionally managed and executed chemical treatment via knapsack spraying, stem injection and leaf-wiping. Over a sustained period of time, our treatments will successfully control and prevent the spread of knotweed.
When buying a property most mortgage lenders will insist on proof that there is a Herbicide KMP in place.
Herbicide treatment, however, does not remove the rhizome from the soil of the property. Therefore, where long term herbicide control is undesirable or where there is a plan to disturb the rhizome contaminated ground, the alternative treatment method is excavation.
Japanese Knotweed Removal Manchester
Excavation can provide complete Japanese knotweed removal. Our full excavation programme involves removing all the plants’ underground rhizome. Works should be carried out by experts such as ourselves, as a fingernail-sized fragment of rhizome remaining in the soil can regrow.
Excavation of Japanese knotweed will cost into the thousands of pounds due to the labour, machine, waste removal and reinstatement costs. However, it can completely remove the problem allowing free use and/or development of the property. We provide cost-efficient excavation through our experience in achieving complete removal while minimising waste volumes.
