All mine are in pots, deciduous and evergreen. If you are not sure which is which at this time the deciduous ones have narrow leaves, and the evergreen ones are much thicker.
The evergreen ones are kept in a cold greenhouse over winter, before the first frosts, and come out again in spring. Precisely when depends on the weather in your area but again don't risk frosts. Keep the compost slightly moist at most.
The deciduous ones are left until the leaves die down, and removed, and then I put a bin liner over the pot to keep the rain out and give a little bit of protection. This comes off in say late Feb/early March, and you don't have to worry overmuch about frosts ( they are hardy!) This seems to work for me in the deep south.
If in doubt and you have room take all of them under cover.
I have never removed any from their pots, leaving them until they get so congested the flower power diminishes, which will take several years. I have some on their final warning. Incidentally mine seed into the gravel they sit on so I have babies to bring on for future plantings. they are very easy to tease up and pot.
