What is Japanese Knotweed?

Japanese Knotweed is a perennial weed that grows and propagates quickly if it is not controlled.

The weed suppresses all the other plants and flowers growing around it from its crown and rhizomes (root system) that spread extensively below ground.

The shoots die off above ground in the winter and re-emerge above ground again in late spring, early summer months.

Any effectively- established shoots can grow in excess of 9ft high and can colonize the soil within a few years.

There are plenty of articles that say you are able to eliminate the roots with chemicals, however, you will need an NPTC qualified person to use any chemicals as a result of new legislation which covers the control, and removal of Knotweed.

There are several misconceptions that say it is possible to remove Knotweed yourself, however, it is an extremely difficult and intricate procedure. Doing it yourself or not using an expert often makes it spread and establish itself in other areas resulting in a bigger problem.

In the height of the growing season, 60% of the Knotweed plants roots are underground so removal is incredibly difficult.

It spreads wildly from one tiny fragment of crown or rhizome.

How do you control Knotweed Stoke Bishop?

There are many different methods of removing Knotweed and South-West Knotweed Removal Services can advise you of the best and most efficient approach.

Knotweed Stoke Bishop Stem-Injection is a low impact approach to removal which offers little probability of disturbing or damaging the plants growing close to it. Stem injection is normally used for smaller sized areas of Knotweed where it has established itself amongst plants and vegetation that you might want to maintain. The stems have to be established to be thick enough for them to be injected so it can’t be used for a new area of Knotweed. It is a technique normally used when the Knotweed is close to a watercourse as there is no risk of the chemicals running into it. The stem injection approach can be used in dry or inclement weather conditions and the soil can’t be disturbed following the treatment. This method normally needs to be repeated over several growing seasons.

Knotweed Stoke Bishop Foliar Spray Application is often used and is probably the most favourable control method alongside stem injection. The process is used to treat the Knotweed over a number of growing seasons. Dependent on how big the area of Knotweed is it is 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. The soil needs to remain undisturbed in the following years to be an effective solution. This method cannot be used if there are watercourses close by.

Knotweed Stoke Bishop Weed Wiping Method is when the leaves of the plant are wiped with a sponge soaked with the required herbicide. it is a low impact treatment that does not kill or disturb the plants surrounding it, nevertheless, its use depends on how big the area of knotweed as a larger area will take a long time for the leaves to be wiped by a specialist. The method can be used if the growth is near a watercourse.

Knotweed Stoke Bishop Bund/Stockpiling Method is a treatment combining stem- injection or foliar application, followed by the Knotweed being dug up and taken to a different location on site where the emergence of ‘new shoots’ can be subjected to further herbicide application. This method can be used on sites where you need the removal of the knotweed to be quick and not done over several seasons so is therefore really beneficial to building plots and development sites as work can continue immediately. The site has to be large enough to accommodate the dug up Knotweed in another area as there are legal responsibilities and large costs associated with it being moved to another location off-site.

Knotweed Stoke Bishop Cell Burial/ Root Barrier Method is a treatment used when there is sufficient space on a site to create a cell burial area or a root barrier system to avoid the substantial cost of transporting the soil and waste to a licensed landfill. Cell burial involves the dug up Knotweed waste being buried to a minimum depth, or 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 danger of cross-boundary contamination. Again, it is a method used and often suited for development sites when construction work needs to start promptly.

Knotweed Stoke Bishop Excavation & Removal Off-Site is a legitimate and quick control option that has its advantages for development sites if done correctly and by a Knotweed specialist. There are many Knotweeds Authorities who are not advocates of this as a method as it raises substantial logistical difficulties. The challenge being it comes with a higher than normal risk of the Knotweed spreading to other locations and there is a significant cost associated with securely transporting the material to a designated and licensed landfill site. There is also a significant duty of care required under the Environmental Protection Act( EPA) 1990 when moving Knotweed material. In conclusion, Knotweed Ammanford  Excavation & Removal should only be used as an absolute last resort.


Is Knotweed Poisonous?

Japanese Knotweed isn’t toxic and poisonous to humans or animals like some other extremely invasive plants. It isn’t harmful to touch, nonetheless, you should always use extreme care when close to it to prevent it from unintentionally spreading.

Japanese Knotweed is often referred to as ‘poisonous’ by developers and homeowners due to its extremely invasive growth, its capacity to spread from a tiny particle left and how difficult it is to eliminate entirely.


Knotweed Misconceptions

(a few 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 performed to a satisfactory standard then Knotweed won’t grow through solid concrete, it won’t destabilise solid foundations and it is highly unlikely to ‘cause’ structural damage. In fact, these claims are inaccurate, to say the least, and in many cases, totally false.

Nonetheless, in certain situations, if foundations or concrete are old, badly constructed and have pre-existing cracks or fractures, then Knotweed will unquestionably exploit any weakness in its quest for light and water and can rapidly establish itself, whilst exacerbating the initial crack and perhaps cause the structure to disintegrate. This is where the misconceptions often come from.

Be aware Japanee Knotweed doesn’t always grow in rural areas and there are lots of towns and cities where it is prevalent.
