Indoors or outdoors?

[macavity]

Do you find your succulents survive Winter outdoors in a greenhouse, or do you bring them in? Until now, my plants have always stayed inside all year round but this year I finally bought a greenhouse (rigid plastic on metal frame, quite small) in the hope of actually seeing something flower. I can see sub-zero temperatures hovering on the horizon and don't know if I ought to bring them in, or if they will survive where they are!
For anybody who doesn't already know me, I'm a student living on the outskirts of SE London in a tiny flat with cats who could play pot-throwing in the Olympics, so any way of keeping the plants outside would be very helpful as long as it doesn't cost a fortune. All (sensible) suggestions welcome!

It depends entirely on what you grow and the aspect of your greenhouse, I would say - so more info, please.

Some cacti and succulents will fold up as soon as the frost touches them, others are bomb proof. I have around 1500m2 of garden in southeast Essex, approx. half of which is landscaped as an arid garden with maybe 2 dozen species of cacti growing outside year round and Heaven knows how many succulents. Some of them get a cover for winter, many don't.

As you haven't really left yourself much time to do the research I'd bring them in. If space is a problem consider out-of-the-way places like on tops of wardrobes and under the bed. So long as it's coolish and the plants are dry most cacti will be fine. Leafier other succulents might prefer a bit of brightness.

My plants are a very random mix from lots of different places, so it's difficult to list them all! Mostly succulents from southern Africa/Madagascar (euphorbias, pachypodium, lithops, a few crassula & various other individuals, including one prized hoodia gordonii), along with some cacti from assorted places. It would probably be easier to take some photos if this will help anybody? I have brought them all indoors for now but it would be very helpful if someone can let me know if any particular genus is likely to be alright outdoors.

That's easy. None of those.....
