Not now, no, I'm afraid they should be left to overwinter, then pruned back as growth begins next year.

Could you move them to a sunnier spot?

Yes I will do. I really want to dig up all my borders and have a really good re-organisation but am a little intimidated to do it! (on my own) so instead I am trying to do doing little bits at a time. Also will give laburnum tree a trim on the lower branches to let some more sun in. Have ordered some epimediums to plant underneath, they will hopefully like their semi shaded spot.
