Yes, I think I'll do that Jenny. Thanks to all of you for your advice.

Someone questioned whether the hebe had outgrown the container...? If
it has, is there a way to prune roots (I think my mum used to do that
sometimes) so it could go back in. Or do you think the time has come to
set it free in the garden?

Finally, does this pruning approach work on lavender as well?
