After a few weeks, roots will start to appear, and the plant can be repotted or planted into the ground.
Division Propagation
Division propagation involves dividing the mature plant into smaller sections. This method is best carried out during the spring or fall months. Dig out the entire plant and carefully divide the root ball into several parts, making sure that each part has healthy roots and foliage. Each section can then be planted individually in the ground or in a separate container.
