I would suggest that you go looking for a caterpillar. Vine weevils eat notches out of the edge of the leaves, rather than in the centre.

Thank you SO much. I had vine weevils in a tree I bought from a nursery a few years ago. Thought I’d got rid of them. Apparently not!
Thanks again.

I thnk there will be other things nibbling than just vine weevils. have a closer look under the leaves for caterpillars too.

I thought that was what I had suggested. The damage does not look like Vine weevils to me.

yes I agreed with you as Janet implied she still had vine weevils :o)

also is this not something like Aucuba rather than rhododendron?

I wondered about the id too!

Thank you for all comments. I thought this was rhododendron because the chap who gave it to me said so!!
I have looked under leaves - nothing - shaken them during darkness (over upturned umbrella - how I caught weevils last time) - nothing! Have given it a soaking of anti weevil solution, in case BUT we do have lots of snails etc (live alongside a field so) possibly they could be culprits, though no trails!
Pity because the plant is SO healthy otherwise.
