How to Choose the Right Japanese Knotweed Removal Method?

The choice is between herbicide treatment and the physical removal of Japanese knotweed. Total eradication ensures that the weed is either completely removed from the property, or completely killed, whereas treatment may only control it's spread.

Why is Japanese Knotweed Removal Important?

Japanese knotweed (Fallopia japonica) is a non native invasive plant that appears in spring and can grow by up to 10cm a day, producing white flowers around September or October time. Japanese knotweed removal is therefore vital to stop the spread of this aggressive plant. Whilst it is lush green in colour with a stem that can appear to look like bamboo, Japanese knotweed must not be confused with other herbaceous plants. Japanese knotweed is a serious problem for developers and their professional advisors, for contractors, home owners and landlords. Environet can help with Japanese knotweed removal.

Identifying Japanese Knotweed Before Removal

Japanese knotweed is usually easy to spot, unless someone has attempted to conceal it. In summer it has lush green leaves that are usually flat and often shovel or heart shaped in appearance. It grows from its rhizome system in the ground from early spring with new shoots appearing as early as March. These quickly develop into tall stems or canes which can look similar to bamboo. In the UK it spreads from the crown and the underground rhizome system rather than through seeds. The weed can grow up to a metre a month and easily grows below concrete and tarmac, causing damage to property, buildings, roads, driveways and drains. The plant produces beautiful white flowers around September and October. Find out more about Japanese knotweed identification.

What Does The Law Say About Japanese Knotweed Removal?

Japanese knotweed and the soil it infests is classified as a controlled waste if it is being taken off site. This means it is subject to all waste legislation under the Environmental Protection Act 1990. It is a criminal offence to consign or dispose of Japanese knotweed in a way that contravenes the regulations. Any material containing Japanese knotweed must be taken by a waste carrier registered by the Environment Agency to a registered landfill site authorised to accept Japanese knotweed. Under the "duty of care" be aware that it is the responsibility of the person consigning the waste to accurately classify the waste, they should clearly state it contains Japanese knotweed, and ensure it is taken by a registered waste carrier. Waste transfer notes should be obtained to provide an audit trail between consignor, waste carrier and landfill site. 

The Wildlife and Countryside Act 1981 makes it a criminal offence to plant or otherwise cause Japanese knotweed to grow in the "wild". 

A more widespread legal tool is civil action under private nuisance where claims can be brought against a landowner who allows his/her knotweed to spread into adjoining land. We call this Japanese knotweed encroachment.

Insurance Market to Cover Japanese Knotweed

It's taken many years for the insurance market to wake up to the problem of Japanese knotweed. A few years ago you couldn't get any cover for Japanese knotweed, the risk remaining fair and square with the property owner, to pay for the costs of treatment, for any claims made against them from aggrieved neighbours being the victims of encroachment, and for repairs to damage caused to property.
