Cultivation and Care

Successful Bougainvillea cultivation requires attention to specific growing conditions.

Optimal Growing Conditions

Sunlight: Bougainvillea thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal blooming.

Soil: Well-draining soil is essential to prevent root rot. Sandy or loamy soil with a slightly acidic pH is ideal.

Watering: Once established, Bougainvillea is drought-tolerant. Water deeply and allow the soil to dry out slightly between waterings.

Temperature: Bougainvillea prefers warm climates and is frost-sensitive.

Pruning and Training

Pruning: Regular pruning encourages branching and flowering. Pruning is best done after a blooming cycle.

Training: Bougainvillea can be trained to climb trellises, fences, or walls, or shaped into shrubs or standards.

Fertilization

Fertilize Bougainvillea during the growing season with a balanced fertilizer to promote healthy growth and abundant blooms.

Avoid over-fertilizing, as it can lead to excessive foliage growth at the expense of flowers.
