Bougainvilleas bloom *after* a dry spell. If they are watered on a regular basis then they will not bloom very often or very much. If you're keeping them consistently moist then you need to try letting them dry out some between waterings.
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others. ~~ Sharon Brown
