Bf, they're much better off outside as soon as the weather allows. They will easily cope with temps in single figures, even low single figures. Mine go undercover from about November to early March.
They always shed leaves over the winter period, new ones appear in spring. It's part of the plant's natural regeneration process. I don't fertilise over winter when the plants are essentially dormant but I do keep an eye on the soil's moisture levels. Once they're outside and the weather is warming up, I fertilise roughly weekly. Like anything in containers, regular watering flushes out nutrients.
I've never found the need to prune much beyond taking off any dead, weak or crossing branches.
