Japanese Knotweed is now regarded as the single most problematic invasive species in the UK. Knotweed control is a priority for many land managers and home owners
The vigorous root system and strong growth can, in certain circumstances, damage concrete foundations, buildings, flood defences, roads, paving, retaining walls and archaeological sites. It can also reduce the capacity of channels in flood defences to carry water.
It is frequently found in Cornwall, partly due to the mild Cornish climate. It is often found in waste land, often as a result of fly tipping, in gardens, along footpaths, rivers and railways. It forms thick, dense colonies that completely crowd out any other herbaceous species.
The plant is also resilient to cutting, vigorously resprouting from the roots. The most effective method of control is by herbicide application at the flowering stage in late summer or autumn.
It can take several visits to completely eradicate it so we provide a programme of action appropriate to the circumstance.
If you have a problem with knotweed and want the knotweed on your land controlled and removed we offer a service to suit your needs. We will carry out an initial assessment of the site and advise on the best treatment method and likely time frames. After an initial site survey, we will produce a management plan with the recommended treatment programme, which if required can be passed to your mortgage provider. We will then carry out the agreed treatment. If the knotweed is not on your land we will work with you to gain the required consent from the landower to ensure a positive outcome for both parties.
