Water: Purple cestrum thrives in subtropical regions with consistent moisture and prefers regular hydration, needing weekly watering for lush growth. As an evergreen, it requires steady water supply year-round, particularly outdoors, where environmental factors may affect its water needs.

Pruning: Prune purple cestrum in early to late winter by removing dead wood and shaping overgrown branches to encourage blooms and maintain form. Regular pruning fosters healthier growth, prevents disease, and revitalizes old shrubs, ensuring purple cestrum remains vigorous and manageable.

Propagation: Purple cestrum can be propagated by cuttings from healthy stems. Use a well-draining soil mix and maintain adequate moisture. Provide indirect light and moderate temperatures for optimal growth. Wait for roots to establish before transferring to a new location.

Repotting: Repot purple cestrum every 2-3 years in spring for optimal growth. Choose larger pots for proper drainage. After repotting, provide ample indirect light and maintain consistent moisture to support the health and flowering of purple cestrum.
