Japanese Knotweed heatmap
The Japanese Knotweed Heatmap is an interactive online heatmap of Japanese knotweed sightings across the UK. Designed to inform homeowners and homebuyers of the local presence of knotweed and the potential risk to their property, the data is generated from over 50,000 known infestations, with new sightings added daily.
Here are the top 6 reasons why Japanese knotweed should be removed from residential property:
Protect your Assets. Knotweed will make it more difficult to sell an affected property, impacting its value by an average of 10%. Half of would-be buyers will walk away from a property known to be infested with knotweed. Sellers are required by law to disclose the presence of knotweed – if they don’t, they risk an expensive misrepresentation claim in the courts.
A Growing Problem. Knotweed is programmed to grow, its underground rhizome system extending year on year, infecting more ground. It’s a problem that simply won’t go away on its own, so the sooner it’s tackled the better.
Nuisance Neighbours. Knotweed does not respect property boundaries and those who allow it to spread also diminish the value of their neighbour’s property. This can lead to neighbour disputes and costly civil claims under private nuisance legislation.
Damage. Knotweed can and does cause damage to property. Perhaps not as bad as some might make you believe, but don’t under-estimate the damage the plant can wreak.
DIY Disasters. Knotweed and building or landscaping projects don't mix! If you want to add that conservatory, summer house or home office pod to the garden, tackle the Japanese knotweed first.
The Heavy Hand of the Law. And for those who are still not convinced, be aware that an injunction or Community Protection Notice, otherwise known as an ASBO, can enforce people to act to remove knotweed from their property
Whilst it’s not illegal to have knotweed on your property, there are compelling reasons to act. Do the responsible thing and get it removed, protect the value of your home and avoid neighbour disputes.

Jobs for this month
June 21 is the longest day of the year, and the extra light and warmth encourages the garden to put on an exuberant burst of growth. But this extra light and warmth also means weeds will sprout up from seemingly nowhere. Keep on top of them by hoeing regularly in dry conditions.
