Japanese knotweed removal & treatment

It’s important to select the right method from a reliable specialist to have the best chance of success. Getting it right first time saves the consequential costs of abortive work and delays to construction programmes.

If you intend carrying out landscaping or construction work within a knotweed affected area, a physical removal method is best. Relying solely on herbicide treatment where ground will be disturbed is not recommended due to risk of re-growth and further spread.
