We bought a few of these plants at a garden centre before the summer.
They've looked fantastic all summer and I was wondering whether we
should dig them up and keep them indoors for the winter or whether
they'll survive in the SW (Avon)?

They have never survived for me outdoors in Belgium, but were fine in an
unheated glasshouse. They don't like frosts or wet feet when dormant.

You can try a bit of one outdoors. Against a wall or with minor
protection from the elements it might just be OK in a mild winter. I
wouldn't take the chance with one I was fond of...

I have overwintered daturas in N Yorks so it depends a lot on the weather.

If I should dig them up, do I need to do anything special to them. I
was intending on wrapping them up in newspaper and keeping them
slightly moist.

I try to keep them cool and dry in loose peat but frost free. They only
need water again when they start back into active growth.
