I'd give them a feed and slowly get them used to being outside. Put them out on warmer days but bring them in on a night or put them into an unheated porch/conservatory. after about 2-3 weeks you can plant them out provided it is not frosty.

Don't put them outside suddenly - have you got a cool windowsill - anywhere light but frost free, to acclimatise them slowly to going outside? Then perhaps move them to a cold frame or similar or as you are in a mild spot perhaps the foot of a south facing wall (but they would appreciate a bit of shade there when the sun gets stronger.) Whether they would benefit from repotting depends on how congested the roots are. Unless they are pot bound I would leave them for now. I wouldn't feed them until they are growing again but others may advise you differently. Just keep your eye on them and give a weak feed it they start to look as though they need one.

Oops Seaburngirl - your reply wasn't there when I posted mine.

no worries we are basically saying the same thing :o)

Thanks Stera and Sbg, Ok, I'll put them on the warmer side of my south facing conservatory and look after them until spring has sprung---not long now i hope!
