Probably easie
st to take in autumn, popull off a small shoot with a bud and a couple of leaves. Dip in hormone rooting compound, put in a pot of 50:50 sand/potting compost and stick the pot in a bag on a bright but not sunny windowsill... north-facing is good....., or else in a propagator, keep an eye on the moisture level, wants to be damp but not wet....
