Aeoniums can be multiplied by several methods: 1. Stem cuttings: Cut a stem from the mother plant with a sharp, sterilized knife and allow it to dry and callus for a few days. Plant the stem in well-draining soil and water sparingly until new growth appears. 2. Leaf cuttings: Gently remove a leaf from the mother plant and allow it to dry and callus for a few days. Plant the leaf in well-draining soil and water sparingly until new rosettes appear. 3. Division: Remove the entire plant from its pot or ground and carefully separate the offsets from the main stem. Plant the offsets in their own pots or spaces in the ground and water sparingly until they are well established. 4. Seed propagation: Collect seeds from mature Aeoniums and plant them in well-draining soil. Keep the soil moist and warm until seedlings appear, then water sparingly. This method is the least reliable as Aeonium seeds can be difficult to germinate.
