Bougainvillea not blooming
Bougainvillea should bloom all summer, but you are overwatering. This plant should not receive much water at all. Also make sure that it is in full sun and is not getting too much nitrogem, which makes the branches grow but not the flowers. And remember that bougainvillea is not hardy in your area. Bring it indoors for winter; keep it in a cool spot. Prune in spring.
