Although citrus and olive both can be grown in containers and overwintered indoors in northern climates, olives are much less likely to be productive in indoor containers than are citrus trees. I have excellent results growing citrus in my attached greenhouse; a sunroom or conservatory is also a good option. However, if you lack those possibilities, supplemental lighting can help. Any kind of supplemental lighting can help, but the greater intensity that you can provide, the better. HID (high intensity discharge) lights would be a good choice. Another factor to keep in mind is that the low humidity in most homes over winter and lack of pollinators could contribute to blossom drop. It might be worthwhile to try hand pollination with a camel-hair brush.
