I was reading in a mag about cutting a stem 30cm and putting 1/3 in
the ground and it will grow. Can I do this anytime - might try it
this week.

I think just after leaf-fall is the classic advice; but it should
work reasonably well if the cuttings don't dry out. I always
propagated them by weighing a stem down with a stone and forgetting
about it for a couple of years, though: this is called "layering",
and uncut bushes will eventually do it by themselves even if you
don't want them to.
