Hi

I'd like to get some Japanese Knotweed as an ornamental plant for the
garden.

I know people have run into difficulties if they let it get out of
control, so to forestall any problems I'd plan to grow it in a large pot,
or possibly a raised bed.

Besides making sure it doesn't set seed and pruning regularly to keep it
in check, are there any other gotchas to bear in mind?

Cheers

Clive
