Japanese knotweed is one of the most invasive weeds throughout the globe. It is so invasive that many banks and building societies will refuse to lend on a property that is affected with knotweed. In the UK it is an offence to plant Japanese knotweed on another person’s property, the law even says you can receive a hefty fine or a prison sentence for doing so

Japanese knotweed has no natural enemies outside of its native Japan; where its growth is controlled by fungi and beetles which feed exclusively on knotweed. This lack of natural enemies allows it to grow exponentially  in forgien lands and a single plant can reach heights of 3-4 metres, which is taller than an adult man.

The root system of Japanese knotweed can also cause damage to building foundations and drainage systems, making it a real problem for property owners.

Perhaps the worst thing about Japanese knotweed is its toughness. Only particular herbicide treatments will truly kill off Japanese knotweed and simply cutting it or uprooting it is unlikely to prevent knotweed from returning; a Japanese knotweed rhizome the size of a fingernail can trigger and entire regrowth.

If you suspect you have a Japanese knotweed problem on your property then it is probably best to seek professional advice. Also, if a property neighbouring yours has Japanese knotweed it is a wise idea to talk to the owners about their Japanese knotweed problem before it spreads.
