How to Care for Bougainvilleas

Plant bougainvilleas in full sun and well-draining soil to encourage flowering. Water bougainvilleas deeply but infrequently, allowing the soil to dry out between waterings. Fertilize bougainvilleas with a high-phosphorus fertilizer to promote blooming. Prune bougainvilleas after flowering to maintain their shape and size. Keep an eye out for pests like caterpillars and aphids, and treat them promptly.
