Pruning aeoniums after they flower Q: Can you tell me how to prune aeoniums once they bloom?
Cut back the bloom stalk as far as you can go and/or to where it meets the stem of the plant. It’s important to understand that aeonium rosettes are monocarpic, meaning when they bloom they die. With shrub-forming aeoniums such as Aeonium haworthii, this is no great loss because the plant consists of numerous rosettes. With single-trunk aeoniums such as ‘Cyclops’, this may mean the loss of an entire plant. When aeoniums bloom, the rosette elongates into a multibranched flower spike that can be quite showy. Eventually, this will need to be deadheaded. New little rosettes may circle the cut stem, but you can’t count on this happening. Aeonium flowers make wonderful cut flowers. They’ll last quite a while in a vase, even without water.
