Water: Orange clock vine, native to East Africa, thrives in tropical-like conditions with consistent moisture. It prefers soil that is evenly moist yet well-drained, needing watering twice a week. Higher humidity levels benefit its growth, and proper watering enhances its vibrant flowers during the active season.

Pruning: Orange clock vine, recognized for its vibrant orange flowers, benefits from early spring pruning to stimulate growth and shape. Cut back overgrown or dead stems to the base after the last frost for optimal flowering. Regular care prevents pests and diseases, enhancing its lush appearance.

Propagation: Orange clock vine is propagated through cuttings from healthy, non-flowering stems, typically 4-6 inches long. Strip lower leaves, use rooting hormone, and plant in well-draining soil. Maintain moisture and warmth, using a plastic cover for humidity; acclimate gradually after rooting and new growth appears.
