A friend grew about 20 last year, cut them down in the Autumn (2008), mulched and left. This year only one came up and here garden soil is relatively moist but drains well.
I can ask more questions like 'Where are they- pots or borders?' 'Are they the taller cutting ones?', but you won't be able to respond to me!

O..? Honestly the avatar said 'Guest' with the tree with a question mark in it. Which is why i repsonded how i did! Honestly, honestly, honest.
Bit strange...

How odd... oh well!

I dont tend to cut mine down til the spring. and they come back every year.
The ones in pots could be put outside in the lea of a wall but dont forget to water them. then spring split them and repot/replant in the ground with some compost dug in too. They may not flower that year but will come good next yr. it is well worth the wait.

My grandad always lifted his in late Autumn and had in them in pots in the cold greenhouse until Spring. Mind you, the winters have changed alot since he was alive and gardeners did many things differently. They seemed to have more time.
