Re: Growing olive tree in container
To successfully flower olives that must be overwintered inside, keep the plant in a cold but not freezing room with plenty of indirect light. The night time winter temperatures should be consistently between 30-45 F. Logees, a seller of container citrus and other edibles, has just published a book called Growing Tasty Tropical Plants in Any Home, Anywhere. You might find some better specific information there. I have not read the book but did see that my Library system has it, so you should be able to get a hold of it from your library too.
