What Is Japanese Knotweed Brislington?

Japanese Knotweed is a perennial weed that grows and advances speedily if not managed. The weed suppresses all the other plants and flowers growing close to it from the crown and rhizomes (root system) that spread extensively underground. The shoots die off above ground in the winter and re-emerge above ground once more in late springtime, and early summer season. Any effectively- established shoots can grow over 9ft high and can colonize the soil within a few years. There are many articles that say it is possible to eliminate the roots with chemicals, however, you will need an NPTC qualified person to make use of any chemicals resulting from new legislation which covers the management, and removal of Knotweed and the use of herbicides.

There are myths that say you can remove Knotweed yourself, however, it is an extremely difficult and intricate procedure and frequently, not successful unless you employ an expert in knotweed.

In the peak of the growing season, 60% of the Knotweed plant is its roots underground so removal is very difficult also it spreads wildly from one tiny fragment of crown or rhizome. Removing Knotweed material without significant knowledge carries a very high probability of scattering the plant to other regions of the soil which were previously unaffected.

How do I get rid of Knotweed?

There are different methods of removing and controlling Knotweed and a Knotweed Expert can advise you on the best and most efficient procedure for your property and the area you live in. We offer Knotweed services for residential business and development sites and our services are bespoke to your needs and where the knotweed is present.

Stem-Injection is usually a low impact approach to removal and there is little chance of disturbing or killing the plants growing close to it. The stem injection technique is normally used for smaller sized areas of Knotweed where it has established itself among plants and vegetation that you might want to maintain. It’s also a method usually used when Knotweed is near a watercourse as the herbicides used won’t run into the water and become an environmental issue. The stem injection process may be used in dry or inclement weather conditions and the soil can’t be disturbed following the treatment.

Foliar Spray Application is often employed and is among the most favourable control methods along with stem injection. The method can be used to treat the Knotweed over a number of growing seasons. Determined by how big the area of Knotweed is it is frequently sprayed 2- 3 times in the first year and once in the subsequent years. The chemical used is an Environment Agency approved herbicide and requires dry weather conditions and the soil to remain undisturbed in the following years to be effective.

Weed Wiping Method is when the leaves of the plant are wiped with a sponge that is soaked with the necessary herbicide. It’s a low impact treatment method and doesn’t kill or disturb the plants surrounding it, nonetheless, its use depends upon the size of the area of knotweed and is mainly used on smaller growth areas before it has grown and spread out of control.

Bund / Stockpiling Method is a blended treatment that uses stem-injection or foliar application, followed by excavating the underground material and removing the soil and materials to a different location in which the emergence of ‘new shoots’ can be subjected to further herbicide application. This technique can be used on sites where you need the removal of the knotweed to be quick and not done over several seasons so is consequently especially beneficial to building plots and development sites as work can continue straight away.

Cell Burial / Root Barrier Method is a treatment employed when there is sufficient space on-site to create a cell burial or to utilise a root barrier system to avoid the considerable costs of transporting the soil and waste to landfill. Cell burial buries the Knotweed waste to a minimum depth, or if encapsulated within 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 danger of cross-boundary contamination. Again, an approach generally used on development sites when development work has to commence promptly.

Excavation & Removal Off-Site is a legitimate and fast control alternative that has its advantages for development sites if done correctly, nonetheless, a great deal of Knotweeds Specialists are not advocates of it simply because it raises significant logistical obstacles. The challenge being it comes with a higher than normal chance of the Knotweed spreading along with the cost of securely transporting the material to a designated landfill site. There is also a substantial duty of care requirements under the Environmental Protection Act (EPA) 1990 when using this method and only Knotweed Specialist should consider using this approach. In summary Excavation & Removal must only be used as an absolute last measure.

Is Knotweed Poisonous to Dogs, Cats and People?

In simple terms, Japanese Knotweed is not toxic and harmful to dogs, cats, humans or any other animals like some other highly invasive plants. It’s not harmful to touch, nonetheless, use extreme care when in close proximity to it to avoid unintentionally allowing it to spread.

Japanese Knotweed could possibly be termed as ‘poisonous’ by developers and homeowners because of its highly invasive growth, capacity to spread from a tiny particle left and just how difficult it is to remove completely.

Some Knotweed Common Myths (several of which are taken advantage of by some contractors for financial gain)

“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 is not going to grow ‘through solid concrete, it does not destabilise solid foundations and it is highly, highly unlikely to ‘cause’ architectural damage. In truth, these claims are misleading, to say the least.

Nonetheless, in a few instances, if foundations or concrete are old, badly built and have pre-existing cracks or fractures within, then Knotweed will certainly exploit any weak point in its search for light and water and will swiftly establish itself, whilst exacerbating the original fracture and possibly causing the structure to disintegrate.
