Wealdens Japanese Knotweed

What is Japanese Knotweed (Fallopia japonica)? 

European adventurer Philipp von Siebold transported Japanese knotweed from a Japanese volcano to Holland. By 1850 a specimen from this plant was added to the Royal Botanic Gardens, Kew. It was favoured by gardeners because it looked like bamboo and grew everywhere. The rest as they say is history.

It’s growing near our property, what can I do?

  • If Japanese Knotweed spreads from one property to another the applicable law is that of private nuisance.  A private nuisance is an act or omission which is an interference with, disturbance of or annoyance to a person in the exercise or enjoyment of his ownership or occupation of land. Now this may sound rather draconian but essentially the owner of the adjacent land must carry out remedial measures to prevent the plant spreading. To do nothing can result in others taking formal action.
  • If you think you are safe from risk because the JK is growing next door but hasn’t appeared in your garden then think again. The Royal Institute of Chartered Surveyors provides guidance to building surveyors for JK. They publish guidance that specifies where knotweed is within 7 metres of a habitable space in your property, either being located within the boundaries of your property or in a neighbouring property; it presents the highest category of risk (Level 4).
  • A Level 2 risk is also applicable where knotweed is located to neighbouring property or land and is within 7m of your property boundary. 
  • If JK is growing in your neighbour’s property we can install root barrier system that can restrict the spread of growth into your property. A treatment regime will ensure that any infringement onto your property is dealt with.
  • We do recommend that in the first instance you ask your neighbour to control the spread of the invasive weed onto your property. This is best done by letter requesting the actions you require to be taken and by when. We can provide this service on your behalf.
  • The neighbour should also treat the plant in your property as well, that’s because it originated from their property (our survey will provide evidence).

 

Further information

  • Any plant that is 'non-native' means that it is not originally from that area, so it has been brought in - or 'introduced'- either deliberately or accidentally. An invasive species is one that can cause economic, environmental and/or human, animal or plant health problems.
  • While it may seem like a mouthful to refer to group of plants as 'invasive non-native species', there is a reason for doing so. Not all non-native species are invasive and, equally, native species can also become invasive.
  • For example, the common stinging nettle is a native plant that has become invasive in some areas thanks to nutrient pollution from modern agricultural and industrial practices. Likewise there are many garden plants introduced from abroad that pose no threat to the wider environment. The problem with plants that are both non-native and invasive is that, as well as being naturally tenacious, they have the advantage of surprise: our own native flora has not evolved alongside them and so is even more ill-adapted to compete.

Non-native species are also sometimes referred to as aliens!
