See the 'Growing a Bougainvillea Standard' section, about 2/5 down the page, and the sections just above that, in the link attached below. Unfortunately, as is explained in the article, the graphics are missing. You can also google 'bougainvillea standard' for lots more information.

Here is a link that might be useful: Bougainvillea Information by Gordon Braswell

brandon7- thanks for that link. What a fountain of info. I've overwintered one up here for several year and picked up several pointers from that article.
