yes you can. if there are any suitable bits you will be able to use them as cuttings.

Thanks SBG I'll do that. In the past, I've just stuck sideshoots in pots containing other plants and that seems to work. Can I cut the main stem back as well? It's too cold to do much at the moment but I'm planning in the hope of better weather.

you can but you may lose the parent plant, but if you get lots of babies .......
