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."

I think the point is that there are many groups around where gardening
is discussed, and many of the posters in those groups do not appreciate
the varied climatic conditions encountered in a maritime climate. Indeed
I have half a dozen climate zones in my own garden!
