Japanese Knotweed is a perennial weed that grows and spreads fairly quickly if not managed. The weed suppresses all the other plant life growing around it from its crown and rhizomes (root system ) that spread extensively below ground. The shoots die off above ground in the winter months and re-emerge above ground again in late spring, early summer. Any effectively- established shoots can grow in excess of 9ft high and may colonise the soil within a few years. There are several articles that say you can kill the roots with chemicals, however, you’ll need an NPTC qualified person to use any chemicals resulting from new legislation which covers the management, and removal of Knotweed. There are many misconceptions that say it is possible to remove Knotweed by hand, however, this is an extremely difficult and intricate process and frequently, not successful unless you work with a knotweed expert. In the peak of the growing season, 60% of the Knotweed plant is its roots underground so removal is extremely challenging also it spreads wildly from one tiny fragment of crown or rhizome. Removing Knotweed material without substantial knowledge has a very good risk of spreading the plant to other parts of the soil which were previously unaffected.

How to eliminate Knotweed?

Stem-Injection is often a low impact method of removal and there is little likelihood of disturbing or killing the plants and flowers growing around 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 would like to maintain. Additionally, it is a method often utilised when Knotweed is in close proximity to a watercourse. The stem injection process can be used in dry or inclement weather conditions and the soil can’t be disturbed following a treatment.

Foliar Spray Application is frequently employed and is one of the most favourable control methods along with stem injection. The technique is used to treat the Knotweed over numerous growing seasons. Dependent upon 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 needs dry weather as well as the soil to remain undisturbed in subsequent years to be effective.

Weed Wiping Method is the leaves of the plant being wiped with a sponge which is soaked with the required herbicide. This is a low impact treatment method and does not kill or disturb the foliage encircling it, nonetheless, its use depends on the size of the area of knotweed.

Bund/Stockpiling Method is a blended treatment using stem-injection or foliar application, followed by digging up the underground material and removing the soil and material to a different location where the emergence of ‘new shoots’ can be subjected to further herbicide application. This method is employed on sites where you need the removal of the knotweed to be quick and not done over several seasons so is consequently is especially good for building plots and development sites as work can carry on at once.

Cell Burial/Root Barrier Method is a treatment employed if you have enough space on site to create a cell burial or making use of a root barrier to avoid the considerable expenses of transporting the soil and waste to landfill. Cell burial buries the Knotweed waste to a minimum depth, or if encapsulated within a geomembrane 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, a method frequently suited for development sites when building work needs to commence quickly.

Excavation & Removal Off-Site is a legitimate and quick control option which has its advantages for development sites if performed correctly, however, a great deal of Knotweeds Authorities are not advocates of it simply because it raises significant logistical difficulties. The challenges being there is an extremely high chance of the Knotweed spreading along with the cost to securely transport the material to a designated landfill site. There’s also a considerable duty of care requirements under the Environmental Protection Act (EPA ) 1990. In conclusion, knotweed removal and excavation must only be used as an absolute final option.

Is Knotweed Harmful to Dogs, Cats and People?

Essentially, Japanese Knotweed is not toxic and harmful to dogs, cats, humans or any other animals like some other highly invasive plants. It is not harmful to touch, nevertheless, always employ extreme care when near it to avoid unintentionally allowing it to spread.

Japanese Knotweed would probably be known as ‘poisonous’ by developers and homeowners due to its extremely invasive growth, the capability to spread from a tiny particle left and just how difficult it is to remove fully.

Some Knotweed Common Myths (some of which are exploited 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 a satisfactory standard then Knotweed will not grow ‘through solid concrete’, it won’t destabilise solid foundations and it is highly, highly unlikely to ‘cause’ architectural damage. In fact, these claims are deceptive, to say the least, and perhaps, completely false.

However, in certain situations, if your foundations or concrete are old, badly built and have pre-existing cracks or fractures within, then Knotweed will certainly make use of any weakness in its pursuit of light and water and definitely will rapidly establish itself, whilst exacerbating the initial fracture and potentially cause the structure to disintegrate.
