Hi there. I have a large (8 foot) Viburnum in my garden that is out of control. It's huge and it has been seriously damaged by frost during this year's storms. Can anyone advise as to what's best to do? I'm wary of cutting it back as the leaves seem to be at the end of rather large stalks, but can't really leave it as is. If I cut it back will it defoliate and recover? TIA for any advice. MA.
