RHS info here: http://www.rhs.org.uk/advice/profiles0604/japanese_knotweed.asp A few other sites around tend to the building industry advice. Basically, spray to the manufacturers instructions, bury shoots 5m, do not add to compost or use flails to cut as the bits of the plant will sprout again all over the place.

It also a controlled substance for disposal so don't chuck bits of it over the fence or you can be prosecuted. The young shoots can be eaten - rather you than me though, and it would take a long time to get rid of it that way alone.

A very difficult weed to get rid of, the best method i have found is to cut the hollow stems in the spring or early summer and spray the freshly cut stems with a suitable herbicide ie roud up, at the given instructions, then dig as much root out as you can in the autumn. Dont be surprised if you have to repete the proccess a couple of times..

Best of Luck.

Thanks both of you. I wasn't aware that it was under legislative control.

It can be very damaging too.
Here's a few techniques for eradication covered by the environment agencies 'code'
cutting
buriel
excavation and landfill
weedkiller application
Japanese knotweed comes under so much legislation, it's worth doing some research before tackling the problem
