I never used to when I had it, used to wait till Spring and then cut it back pretty hard.

Hmm...thanks, I think I'll check with the Nursery that sent them.

I did the same as Bamboo and waited until spring

Do you cut them back really hard?

Reasonably, but not excessively. They often look a bit bruised and battered at the end of winter, so I'd cut back, say, a 3 foot plant by about half if necessary. I wasn't above giving it a bit of light cutting back in mid summer if it got a bit large, but its not entirely hardy, this one, so that's why I'd wait till Spring. By which time, it looked pretty tatty I can tell you... but where you are,Spritz, it might not suffer quite so much.

Oh well - I'll just have to be patient and trust the Nursery. They are very good 'plantspeople'...:-)
