Rule of thumb:

If you wouldn't leave your dog in a hot place for ten minutes, don't leave
an orchid there for five. Yeah, we've all learned that lesson,
unfortunately!

Works for cold too, cue visions of our move from London, England to
Dundee, Scotland at the start of December. On stopping in the Borders
for the night the orchids came into the guesthouse with us instead of
staying in the car and being left to the frost.

Heat is not such a problem up here.
