Thanks, Sue & Zuzu & Cherry. Suddenly a lot of good useful info! The article from AC society provides the basics of growing Camellia in pot: container size, soil mix, and fert. Zuzu's point on 'shade' need for Camellia surprisingly answered my next question. Al's discussion on pot soil in scientific view surprised me (a scientist) with the 'PWT' scenario: a layer of pine bark at pot bottom is a no, no to do, which is contrary to the suggestion from the ACS article! This is a real interesting education to me b4 starting Camellia project. So far no info on 'water Camellia' yet (though container/soil drainage requirement has been much addressed/emphasized). Hope and expect more good info and advice will keep coming... Thanks
Correction: Zuzu has given advice on watering. Thanks
