I have a small new rhododendron which is in a pot . I’ve got the correct soil, fertiliser etc but, the leaves have gone brown and all have fallen off. I think I’ve watered it correctly and have taken care of it but it seems to be struggling.
Can you add a couple of photos to help us out?

I lost a small rhodie to frost this year. Exactly the same symptoms as yours.
-Frost alone won't kill them, unless it was below about minus fifteen or twenty for a spell of time. They're supremely tough shrubs. It could happen if it was a young plant that had been grown undercover and then suddenly put out in freezing weather, and/or if there were other factors. It can be a combination of things, so more info is needed
It's more likely that it's already weakened for other reasons, the most common being that it's been dried out and can't support the foliage. In a pot, that's even more likely.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
