I have been using roundup and weedol even tried the 24 hr fast acting
stuff
but its all useless.

Are you following the dilution and application rates accurately?

yes, in fact I have even tried using a stronger solution.


I have tried smothering the ground with thick carpet but they grow
through.

What kind of time frame?

The carpet has been on the garden two years. It did supress some smaller
weeds and twitch grass but mostly they have just pushed their way through
in the summer. It was a thick carpet too. I really couldnt believe it.

Frankly neither do I.

IME thick carpet does not degrade that fast, and IME nettle shoots do
not have that japanese knotweed ability to penetrate a solid barrier.
