Asexual Propagation
Artemisia afra Jacq. ex Willd. var. friesiorum Chiov. can also be propagated through softwood cuttings and root division methods.
Softwood Cuttings: Softwood cuttings are taken from young, succulent shoots of the plant during the early summer season.

After a few weeks, the cuttings will develop roots, and they can be transplanted into pots or directly into the field.
Root Division: Root division method involves dividing the matured plant's roots into several smaller sections and planting them in separate pots or directly into the field. This method is suitable for plants that are more than two years old. The divisions should have at least one stem and well-developed roots. The divisions should be planted at the same depth as they were in the previous pot or field.
