We lived in the city centre in a Victorian terrace ... our neighbour (renting) planted on Himalayan Balsam.. two years later, despite six foot fences and walls we had several in our garden ... and then more and more appeared, and in the next house and the next.
We kept pulling them up whenever we saw them.
The neighbour moved on ... the landlord sprayed and put a membrane and shingle down.
Now, 10 years since the neighbour moved on, most houses in the street have Himalayan Balsam in their gardens ... don't say you've not been warned
