Japanese knotweed

Got something to say or just want fewer pesky ads? Join us... 😊



My daughter just bought a house only to find she has Japanese knotweed in the garden. She didn't know what it was when she looked round prior to buying, any more than I would have known.

But it wasn't mentioned in the report by the Bank valuer even though there is quite a lot of it and it is close to the house.

In the standard completion questionnaire the sellers were asked if there was any Japanese knotweed and said no. When asked about this after completion by my daughters solicitor when she realised it was in the garden the sellers said they had no idea what it was. This may or may not have been true of course, but hard to prove one way or the other.

Anybody else had Japanese knotweed problems? Any (helpful) suggestions or advice would be much appreciated.

I really hope this doesn't price to be a costly mistake as Japanese knotweed is very difficult to remove.

It's a long slog with glyphosphate. Use it double strength. Some people say cut the knotweed down and pour the glyphosphate down the hollow stems. I have got rid of it several times but you need to keep at it regularly

I don't think not knowing what it is would hold up as a defence, if you sign a legal document stating no to a question it has to be your responsibility to ensure that the question answered is true. As for the plant, it's a right ******* to get rid of and could take a number of seasons to ensure its eradication, there are specialised companies who deal with this plant and they have to return quite a lot to treat it etc. Do not leave it act immediately as structural damage can be caused as it grows very rapidly and foundations are no problem to it. Very bad news and I have nothing but sympathy for your Daughter.

It may be worth speaking to your local council

Don't tell your insurer, they will run a mile.

Problem is seller may say it has since occurred, take photo's as evidence now and get a independent report and have it treated ASAP

A mate of mine owned a company that eradicated Japanese knotweed, and I used to get endless chat about the thing. As others have indicated, council, court and professional eradicators will all be required. Sorry.

And how do we prove they knew it was Japanese Knotweed? If it had been my house I wouldn't have known, unless someone told me

Because they ticked "no" - they should have ticked "don't know" unless they knew how to identify it. Just give Paul Beckett a call on the number above and he will explain all.

If it were your house, you would have found out sooner or later. The thing is a thug (and I say this having grown well over 50 species of bamboo) and would have caused you a problem.

Doesn't help the OP but my niece was well into the process of buying a house in Worthing and then surveyor's report spotted JK.
She withdrew immediately.
