Light: Plant bougainvillea in a location with lots of sunlight. Full sun exposure is essential for bougainvillea plants, and they will not bloom in shade.
Soil: Bougainvillea also prefers a rich, slightly acidic soil with a pH between 5.5 and 6.0.
Water: Water bougainvillea enough to keep the soil moist but not soaking wet. Finding a happy medium in watering is essential.
Prune bougainvillea after it stops blooming.
