Japanese Knotweed
Discussion

Not sure if it differs in England but we looked at a house in Scotland with Knotweed in the garden - one large clump about 4m from the house.
What makes knotweed hellish is it can perpetrate pretty much anything such as concrete tarmac etc it just looks for weaknesses.
...just to offer another view, a Chartered Surveyor I spoke to, who has decades of experience in residential property, said that his firm has never seen a building be structurally damaged by knotweed.What makes knotweed hellish is it can perpetrate pretty much anything such as concrete tarmac etc it just looks for weaknesses.
We know it does/can happen, but like many of these things it has been vastly blown out of proportion.
Yes, it can be a tricky fecker to get rid of, but it can be eradicated fairly simply if the correct procedures are followed.

Just wish the banks would see it that way!We know it does/can happen, but like many of these things it has been vastly blown out of proportion.

I researched diy treatment and its really not that bad nor expensive to do properly. However most lenders want a certificate of removal. This would be useful if you could go the diy route -

And all of that is well and good, but it could be seeding from a source upstream, or an adjacent garden, etc.
I know I'm being pedantic here, but it pays to be clear with terminology. In this country, Japanese Knotweed virtually never produces viable seeds, so that isn't how it grows.I'm pretty sure you meant that it's spreading by vegetative fragments carried by water or from another garden.

There's a local contractor here that deals with Knotweed removal, and I'm sure he does a very good job (and he would eradicate it at least as well as the big firms can) however as he can't produce a 25 year guarantee, his services are of limited value.

Correct, as long as you isolate it it won’t spread to different locations. I think it’s hilarious how people/mortgage companies cry about what is just a plant. With time, persistence and a little know how, it can be permanently killed with £25 worth of glyphosate.

Kills it stone dead.
It doesn't. It will kill it off temporarily, but it will come back in smaller quantities over a few years.Kills it stone dead.
Repeated spraying is definitely needed.
