Gardeners' Notes:

Neutral Cambium On Mar 20, 2007, Cambium from Lamar, AR (Zone 7b) wrote:

Bougainvilleas are famous for their clusters of papery bracts which are infused with shades of intense colors. The flower is nondescript. This bush blooms year around in warm climates, about every 5-6 weeks with resting periods in between which is a good signal to trim to promote flowering. It does best in very bright full sun with frequent fertilization but requires little water to flower.

Here in Florida I've seen this large bush become a nuisance by literally take over any other plants if not kept within bounds by trimming which also promotes new growth & flowering. I have seen these bushes shaped like shrubbery which is not a pretty thing. To do it justice, the majestic Bougainvillea should be trimmed at least once a year then be allowed to wander naturally & cascade over a fence or wall.

By my experience it is a difficult houseplant but I have seen it as a spectacular bonsai. If overwatered, Bougainvillea will not flower & may lose leaves or wilt or even die from root decay.
