Air plants can be propagated in several ways, including: 1. Division: Gently separate the small ‘pups’ that grow around the base of the mother plant and plant them in a new container. 2. Seeds: Collect the seeds from the flowers of the air plant and plant them in a moist potting mix. 3. Tissue culture: This method involves taking a small piece of the plant tissue and growing it in a lab. This is typically done by professionals. 4. Cuttings: Cut a small piece from the parent plant and place it in a moist potting mix. As long as the cutting has a small section of the base attached, it should root and grow into a new plant.
