Japanese Knotweed Control: A Guide

Japanese Knotweed Control

One of the most hated weeds in the UK is Japanese Knotweed as it can be a real problem. This is why Bark and Branch offer a Japanese knotweed control service – in order to help house-holders prevent it from causing damage to their gardens, paths and even their home!

What is Japanese Knotweed?

Japanese Knotweed was introduced to the UK from Japan in the 19th Century, as an ornamental plant. The leaves and stems were felt to be very attractive, as where the creamy white flowers it tends to produce in late-summer and early autumn. Unlike other plants that we tend to tackle as part of our weed control services, it does not produce seeds but instead spreads and propagates itself from very tiny pieces of its underground stems (known as rhizomes).

How to Identify Japanese Knotweed

Fortunately, Japanese Knotweed is easy to identify through its distinctive heart shaped leaves and hollow green stems which feature purple speckles. The stems of the weed tend to appear in early spring and by early summer they will be mature. The plants tend to grow in clumps, which will tend to turn brown in Winter, although they will remain standing if not treated.

Why is Japanese Knotweed Considered a Problem?

Knotweed has very strong roots which are strong enough to push up through concrete and similar hard services, as well as even being able to damage buildings. This means that it can affect homeowners when it comes to buying or selling their house, as many lenders will not offer mortgages to properties which are affected by it, meaning property prices can dramatically fall.

Japanese Knotweed Legislation

The issue of Japanese Knotweed has become such a problem that there are even laws that cover it, including The Anti-Social Behaviour, Crime and Policing Act 2014 which states that individuals and companies must remove knotweed and take action to stop it spreading.

Disposal of knotweed is also a bit of an issue as well, as it is classified as controlled waste under the Environmental Protection Act of 1990.

It can take several years to successfully get rid of Japanese Knotweed as even the tiniest piece of root can regrow very quickly. This is why it is better to get a professional in, who will also be able to dispose of it safely as well.
