Japanese Knotweed Burnham-on-Sea
Treatment & Control Methods from West Country Knotweed Removal
Japanese Knotweed is a perennial weed that will grow and spread quickly if not controlled. It is a weed known to suppress the plant life growing around it just from its crown and rhizomes (root system) that spread extensively underground. Knotweed shoots die out above ground in the winter months and re-emerge above ground again in the late spring or early summer season so often people will think they have removed it, however, it is still growing and spreading underground. Any well-established shoots can grow in excess of 9ft high and often colonize the soil within a few years.
There are numerous articles that say you can kill the roots with chemicals, however, you now need an NPCT Qualified person to work with any chemicals as a result of new legislation which covers the management and removal of Knotweed.
There are some common myths that say it is possible to remove Knotweed yourself, however, it really is an extremely difficult and complicated procedure and frequently not successful unless you work with a Knotweed expert. In the peak of its growing season, 60% of the Knotweed plant’s roots are below ground so removal is extremely challenging and it spreads wildly from one tiny fragment of crown or rhizome. Removing Knotweed without having considerable knowledge carries a very good chance of dispersing the plant to other parts of the soil which were previously unaffected, restarting the process all over again.

How is Japanese Knotweed Removed & Controlled?
There are several methods of removing Knotweed and a Knotweed Specialist like West Country Knotweed Removal can give you advice about the best and most effective approach.
Stem-Injection for Japanese Knotweed Burnham-on-Sea
A low-impact approach to removal and there is minimal chance of disturbing or killing the plants and flowers growing around it. The stem-injection method is used for smaller-sized areas of Knotweed where it has established itself among plants and vegetation that you want to maintain. The method can be used when close to a watercourse as there is minimal chance of the herbicide running into the watercourse. It can be used in dry or inclement weather conditions and the soil cannot be disturbed following a treatment. The stems of the Knotweed have to be reasonably established to allow for the injections to be made.
Foliar Spray Application for Japanese Knotweed Burnham-on-Sea
Is often employed and is probably the most favourable control method along with stem injection. The process is used to treat the Knotweed over several growing seasons. The area of Knotweed is frequently sprayed 2-3 times in the first year and once again in the subsequent years. The chemical used is an Environment Agency-approved herbicide and needs dry weather as well as the soil to remain undisturbed in subsequent years for the method to be effective.
Weed Wiping Method for Japanese Knotweed Burnham-on-Sea
Wipes the leaves of the weed with a sponge soaked with the necessary herbicide. It is a low-impact treatment method and doesn’t kill or harm the plants growing around it. Its use does depend on the size of the area of knotweed and this is not a method used for large areas of growth. The method can be used if the Knotweed is close to a watercourse.
Bund/Stockpiling Method for Japanese Knotweed Burnham-on-Sea
Is a combined treatment using both stem-injection or foliar application, followed by the underground material being dug up and moved to a different location on site. The emergence of any new shoots of Knotweed is then subjected to further herbicide application. This approach can be used on sites where the removal of the Knotweed needs to be quick foto enable construction work to start. The process is done over one season and it doesn’t impact any waterways.
Cell Burial/Root Barrier Method for Japanese Knotweed Burnham-on-Sea
Is a treatment applied when there is sufficient space on-site to create a cell burial or root barrier system which reduces the significant cost of transporting the waste to landfill. Cell burial buries the Knotweed waste to a minimum depth, or if encapsulated inside a geo-membrane it can be closer to the surface of the ground. Root barriers can be installed both vertically and horizontally when there is a risk of cross-boundary contamination. Again, it is a method frequently used for development sites when work needs to commence quickly.
Excavation & Removal Off-Site for Japanese Knotweed Burnham-on-Sea
Is a legitimate and quick control option that has its advantages for development sites if performed correctly and to the required standards. The treatment creates significant logistical problems along with a high cost to transport the waste material safely without the risk of it spreading to a licensed landfill. There is a duty of care required under the Environmental Protection Act (EPA) 1990 when it comes to this removal method. In summary, Excavation & Removal must only be used as an absolute final option and only if you have the required knotweed qualifications and accreditations.
Japanese Knotweed is often referred to as ‘poisonous’ by developers and homeowners because of its highly invasive growth, ability to spread from a tiny particle left and how difficult it is to remove fully. Knotweed isn’t poisonous to humans or animals however it can easily spread from one tiny particle so extreme care should always be taken when touching it or if you are trying to remove it yourself which we wouldn’t recommend.
Japanese Knotweed Myths & Some Facts
- It will grow through solid concrete
- It will destabilise foundations
- It will cause structural damage
- Property affected by Japanese Knotweed is not mortgageable
Essentially, if the previous groundwork or construction has been carried out to an acceptable standard then Knotweed will not grow through solid concrete, it doesn’t destabilise solid foundations and it is highly unlikely to cause architectural damage.
In certain situations, if the foundations or concrete are old, badly constructed and have pre-existing cracks or fractures then Knotweed will take advantage of any weak spots in its search for light and water and can rapidly establish itself. When this happens it can exacerbate any cracks or fractures and potentially result in further damage to structures.
