I believe Japanese Knotweed is a notifiable weed

No, it is not notifiable. You do not have to notify anyone if you have it.
Nor is it covered by the Weeds Act 1959. It is however covered by Section
14 of the Countryside and Wildlife Act 1981, which prohibits you from
planting it in the wild or causing it to grow there.

It's also covered by the EPA 1990 duty of care regs 1991.
To this extent it's a controlled and notifiable waste.
Same rules as Hogweed I think.
