Was there ever a policy of UK-only questions?
I thought I was just
supposed to not rabbit on about USDA 'zones' and ask why people would
grow cucumbers in greenhouses instead of outside. :-)

I think the title "UK.rec.gardening" may give a hint as to the focus for
the group.

Here's what the abc post says:

"Uk.rec.gardening is based in the British Isles for the discussion
of gardening within those islands (snip) Contributors from outside the
British Isles are not discouraged but,because this newsgroup is intended
to help gardeners in the British
Isles, it should be remembered that all questions and answers should
relate to a climate similar to that found in the British Isles. We
thank you for your cooperation in this."
