|My bouganvillas are planted in flower beds. what could be some reasons they are not blooming? they re growing profusely very healthy very green, just no flowers. very disappointing. :(
Bougainvilleas bloom best when they are not in too vigorous of a growing condition. Potbound container plants and in ground plants living in marginally poor conditions seem to be among the best blooming specimens. Cut back on fertilizer and water enough to keep it going but not luxuriously growing. Give the plants only enough water each morning to prevent them from completely drying out. Don't worry if the leaves drop your bougainvilleas will still be okay. Continue this procedure for two weeks, then begin watering daily, and fertilize lightly with a product with a 3 1 2 ration such as 17 7 10 or 15 5 10. The plant should settle down and start blooming in time.
Some people take the drastic measure of root pruning to get their plants to bloom. This is done by forcing a shovel into the soil in 4 locations a foot or two away from the base of the plant, thereby cutting some of the roots. I would only do this as a last resort, such as if it wasn't back in bloom by next spring.
Thanks for the question. Please stop in again soon!
