I have a camellia that is just budding but it is hidden can I move it now and put it in a large pot
I'd leave it till after flowering. It would put too much stress on the plant now.
When it's finished flowering, lift carefully and pot with ericaceous compost, then it should do okay next year.
My thoughts are the same as Dave Morgan.
Thanks very much we will have to walk down the path and then enjoy the flowers
