What should I do about a viburnum tinus spolit by slugs?

I just planted one of these, I thought they were suppose to be pretty resistant to most things. Mine apparently got too wet from a lot of rain we've had and is not looking so good. The nursery staff told me to remove any mulch from around the shrub to help it dry. I don't know how thick yours is at the bottom but if you prune it maybe thin out the bottom some so the base can get some air. I've read pruning is done right after blooming has finished, if you wait too late it will only have blooms on top next year. Keep me updated.

Dig it out and find something nicer. I had one that was eaten by vine weevil every year, it just wasnt worth the effort

Prune it hard after flowering and it will recover. Do the leaves look like the plant has been shot at. small holes with brown edges/lacey effect? if yes it is a pest that i cant remember what it is called. collect all the dropped leaves and burn to remove the overwintering infection. I have decided i have to do it to mine too. Never found slug damage though.

welcome to GoY.

Thank you so much for your replies. Yes - it does look like it has been shot at with brown edges round the lacey holes. It is beginning to to flower but looks rubbish and am so fed up with it have taken the plunge and given it a great big prune - including round the base as suggested. At least it is less of any eyesore now. Will wait and see if it does recover on its own before taking any further action. Will keep the question updated for those who may be interested.

Just in case it's of any help to you, I was shocked to find loads of snails by my shed. They had hidden themselves under an old bag of compost!!! Another place was the long leaves of red hot poker. Have a look round your garden to see where they are living, it might save future plants?
