The Q&A Archives: How do you keep them blooming

Question: Bouganvilleas - When fo they begin to bloom. My plants are out of the greenhouse now. They are rich in green leaves but have no flowers.

Answer: Cher,

I apologize for this delayed reply to your gardening question and hope it is still helpful to you. Bougainvilleas bloom on and off through the season but primary bloom is in late winter and spring. Plants that were set back by winter may take a little longer to start blooming. In the tropics bougainvilleas bloom almost continuously. There the day and night cycles are more even. Here in Texas our long summer days seem to discourage them from forming the blooms we so want to see. They bloom better for us in spring, fall and even winter if they are in a warm greenhouse. Their bloom cycle lasts a little over a month. After this the blooms or bracts fall off and the plant cycles through a period of a 6-8 weeks during which it grows leaves and shoots but not blooms. Then it will often enter another bloom period.

Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
