Make sure the pot of bougainvillea is in full sun.
More sun = more blooms. The plant needs at least six hours of direct sun per day to be its floweriest.
Where is the best place to plant a bougainvillea?
Bougainvillea should be planted on higher ground or hillsides, not in water-logged or low areas where water might collect. They will grow best when given enough space to spread out, and should be planted in an area that will allow them a minimum of 5-6 hours of sunlight every day.
How often should you water a potted bougainvillea?
Although bougainvillea is drought tolerant in the ground, potted plants need regular watering. Water your plant about once a week, but let it dry out between waterings. Feed the plant with a liquid fertilizer designed for flowering plants, and apply it about three times during the growing season.
