Question
I have several boganvillias around the yard and they all seem quite healthy and lush, but none of them have any flowering - I mean none at all.  What's up with that?

Answer
Bougs are at their best during the cooler seasons  beginning in October; during the hotter time of the year they color out sporadically. Bougs actually color best when stressed, and that means during the dryer time of the year. You didn't mention where you lived, but if you are getting abundant rain, then that is the main reason for no color. Nick
