How can I make a bougainvillea tree thrive and flourish in my garden?

To help a bougainvillea tree thrive in your garden, plant it in well-draining soil, provide plenty of sunlight, water it regularly but allow the soil to dry out between waterings, and fertilize it with a balanced fertilizer. Prune the tree to promote growth and remove dead or damaged branches. Protect it from frost and pests to ensure its health and flourishing growth.
