Unfortunately, banks WILL refuse mortgages and loans against a property with Japanese Knotweed, preventing property sales, UNLESS a PCA approved Japanese Knotweed Specialist has been instructed to conduct a management plan. Lenders need to know that a reputable & specialist Japanese Knotweed company has been instructed in order to protect their investment

Other problems include:

  • Economic loss, primarily associated with control costs in the construction sector
  • A fragment of Rhizome (the size of half of your fingernail) can contaminate surrounding soil… on the bottom of a shoe, a lawn mower etc. This will result in MORE NEW GROWTH.
  • Aesthetic damage to gardens and landscaping
  • Damage to hard surfaces such as patios and driveways
  • Damage to built structures such as walls, conservatories and out buildings

Japanese Knotweed has distinct characteristics which help to distinguish it from other plants. The optimal time to detect Japanese Knotweed is throughout mid Summer – Autumn. If you have a plant and are not sure it is Japanese Knotweed, here are some characteristics to look out for:

  • Is it lush green in colour?
  • Are the leaves heart shaped?
  • Is the stem ‘bamboo like’ in appearance?
  • Do the leaves shoot from the stem nodes alternatively? In a zig-zag pattern?
  • Does it grow rapidly? (Japanese Knotweed grows incredibly quickly- it’s been reported it can grow 2cm a day!! The stems can reach heights of approx. 3m and the Rhizomes can spread approx. 4m in every direction).
  • For a more in depth guide read more here or click the button below:

In the Pre-Contract Enquiry form (TA6) there is a specific question asking the seller ‘if the property is affected by Japanese knotweed?’. If the seller fails to disclose Japanese Knotweed or knowingly falsifies the non-presence of Japanese Knotweed to the buyer, a claim against the seller could be brought before the courts for ‘Misrepresentation’.

Under the Consumer Protection Regulations, agents acting on behalf of the seller have a duty to disclose any “material facts”. Guidance to the regulations now includes Japanese Knotweed as a material fact.

Unfortunately yes it does. If it has been treated with any kind of pesticide, there is a high possibility the rhizome will go into dormancy, making it more difficult to detect the scale of the Japanese knotweed infestation & to give the infestation the appropriate amount of treatment in subsequent visits.

If there have been attempts at digging or removing the Japanese Knotweed, it will be very difficult to recognize the original extent and spread of the plant.

Rhizome dormancy can be induced by incorrect herbicide application. Where dormancy exists the knotweed may look dead above ground (or may not even be visible) but the rhizome system in the ground remains alive ready to send up new shoots when the dormancy is broken.

A 5 year, in-situ, herbicide management plan is essentially a ‘control’ method which puts Japanese Knotweed into dormancy. As the rhizomes are not being removed from the soil, if the soil were to be disturbed, the Japanese Knotweed would become viable and start to grow again. Disturbing the ground could also fragment the rhizome system, leading to spread and regrowth of the Japanese Knotweed.

As above, if the Japanese knotweed is in dormancy we would strongly suggest you not to do this – if you are looking to redevelop/landscape or disturb the ground, complete removal (excavation) of the Japanese Knotweed is advised.

Knotweed Services will endeavour to keep disruption to a minimum, but inevitably some loss of enjoyment that the property and garden provides will be experienced. The amount and duration of disruption can depend on the treatment method adopted.

  • To minimise spread, if you cannot control access, fencing and warning signs should be used to prohibit unauthorized access into the affected area.
  • During application of herbicide, please keep persons and pets out of the area. The herbicides used are not harmful to mammals if used correctly, however unnecessary exposure should be avoided.
  • Do not allow the above ground knotweed vegetation to be trampled on, cut down or damaged. Damage to the above ground part of the plant makes the treatment using herbicide less effective. In certain circumstances it can also lead to further spread.
  • You should also notify all relevant parties with access to the infestation that the cutting down/pulling out of any Japanese Knotweed is not permitted during a treatment programme as to do so would severely hinder the control of the Japanese Knotweed, or worst case scenario cause new infestations to occur.
  • A 1m boundary should be left around the infestation to avoid contaminating surrounding soil.
  • It is imperative that no Japanese Knotweed is permitted to be disturbed, broken / pulled during an in situ control programme as this will delay control timescales and potentially increase control costs in the end.
