And I'm no help on camellias at all.....I am only an inheritor of the two that were on the property when we bought it and one small one that was given to me...The only thing I would add is that if I were putting one into a container, I would make it as large as possible and I would put nothing but potting soil into it.....it if needs to be in a container, it needs as much soil as possible in there for its roots and nothing like any 'filler' in the bottom, there are varying ideas on the idea of things such as packing peanuts, etc. in the bottoms of containers. I think it may be in "Tapla's" writings on potting soil mixes for containers where he gives the technical reasons for not using fillers at the bottoms. I need to look that up....
