I've got this clematis growing up the fence. I left it at the end of the year because
I didn't know what I was supposed to do with it. Now the fence needs fixing (after
the gales a week ago) and I've managed to disentangle the clematis but it might get
trodden on when the fence gets fixed. Is it ok to cut it right back? Should I dig it
up and move it? Or what?

Many thanks

Liz
