Cultural Requirements

Sunlight

Bougainvillea glabra thrives in full sunlight and requires at least 6 hours of direct sunlight per day to bloom profusely.

Temperature

It prefers warm climates and is not frost-tolerant. Bougainvillea glabra grows best in USDA hardiness zones 9-11.

Soil

Well-draining soil is essential to prevent root rot. Sandy or loamy soil with good drainage is ideal.

Watering

Once established, Bougainvillea is drought-tolerant and prefers to dry out between waterings. Overwatering can lead to root rot and poor blooming.

Pruning

Regular pruning helps maintain the plant's shape and promotes flowering. Prune after each bloom cycle to encourage new growth and flowering.

Propagation

Bougainvillea glabra can be propagated from cuttings. Take 6-8 inch stem cuttings from mature, healthy plants, remove the lower leaves, and dip the cut end in rooting hormone before planting in a well-draining potting mix.

Keep the cuttings in a warm, humid environment and water sparingly until roots develop.
