Japanese knotweed treatment and removal
Consultancy, removal and treatment of Japanese knotweed
To control Japanese knotweed is specific to each property or site, but control, treatment and containment on site is now the preferred option and is tax efficient.
Japanese knotweed treatment needs to start as soon as possible. In the dormant season, the plant may not be visible if the site has been cleared of vegetation, so all development sites should be surveyed at the earliest opportunity and preferably before purchase.
Japanese Knotweed Treatment and Removal Options
Stem injection
This is our standard treatment but may be used in conduction with other methods.
This is the quickest and most cost-effective method of control, 3 years.
Whole area Japanese knotweed removal within the site or to controlled waste site
The quickest option on a development site, but also the most expensive. This option removes the whole area of contamination to a waste disposal site or a more suitable area of the site within site controls.
Important: All information on the infestation, and the work to eliminate it, must be passed to future owners, including site management plans. See our Japanese knotweed removal Services page.
