Hi pudandperce, In answere to the last part of your question, I take it that they are newly rooted cuttings, if so I would keep them protected over winter if thats posible ie a cool green house, conservatory or cold frame, tender plants such as these will adjust better if they are planted out after any fear of frost has passed, the latter half of May should be okay in most areas. This way it will have progresivly warmer weather ahead of it rather than getting colder with the onset of winter.
Pruning should be done in spring, basicly cutting out any weak growth or dead or damaged and retaining strong healthy growth. A sunny south facing position is best trained on horizontal wires. it will benifit from a mulch around the roots in spring and again in late autumn.
Good Luck Tbird+
