Identifying Japanese knotweed

During the summer months the plant 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 look similar to bamboo. In the UK it spreads from the crown and underground rhizome system rather than through seeds. During the summer months the weed can grow up to a metre a month then as the autumn approaches the plant produces beautiful white flowers. Find out more about Japanese knotweed identification.


Why removing Japanese knotweed is so important

Japanese knotweed or Fallopia Japonica is a non-native invasive plant easily growing below concrete and tarmac, causing severe damage to property, buildings, roads, driveways and drains. The plant causes serious problems for developers, professional advisors, contractors, home owners and landlords. Mortgage lenders often refuse to lend where their surveyor identifies the presence of Japanese knotweed on the property and sometimes where knotweed is present on adjoining land. This is due to the risk involved as the plant can cause significant damage and devalue a property. With a management plan in place, secured with an insurance backed guarentee, banks will lend. Check out our FAQ's for further information.

Laws surrounding Japanese knotweed removal

Japanese knotweed and the soil it infests is classified as a controlled waste if it is being taken off the site so 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 these regulations so all contaminated material must be removed by a waste carrier registered by the Environment Agency to a registered landfill site. Under the ‘duty of care’ it is the responsibility of the person consigning the waste to accurately classify the waste, clearly state it contains Japanese knotweed and ensure it is taken away by a registered waste carrier. Waste transfer notes must 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 knotweed to spread into adjoining land. We call this Japanese knotweed encroachment.
