For many aeoniums, the rosette that flowers dies afterward. Cutting off the flower does not reliably reverse that process. On a branching plant, other nonflowering rosettes can survive, so inspect the whole plant before discarding it or cutting every stem back.
Look at each rosette, not only the flower
A rosette is a cluster of leaves at a growing point. On a many-branched aeonium, one rosette can flower while others remain leafy. On a plant with only one rosette, flowering may leave no surviving leafy growth. The outcome depends on the plant’s species and branching habit.
The UC Master Gardener account of Aeonium ‘Kiwi’ explicitly describes the flowering rosette dying and replacement growth surviving. That is different from claiming a perfectly timed snip saves the flowering rosette.
Photograph or label the plant if you do not know its identity. Avoid deciding that it is a non-monocarpic type simply because a flower appears to lean out from the side. Rosette position alone is not a reliable identification method.
Let the display finish, then tidy the spent growth
You can enjoy the flowers while they remain attractive. When the flowering growth is spent, trace its stem and identify nearby healthy rosettes before cutting. Remove the dead portion carefully without taking a living branch with it.
There is no need to rush because pollinators have stopped visiting or petals have changed color. Those observations do not define a rescue deadline. Do not keep cutting farther down a healthy plant in pursuit of promised new shoots.
Some plants retain surviving branches or offsets; others may not replace the lost rosette. Observe what actually remains rather than waiting for a guaranteed cluster of babies from a bare stump.
Keep healthy growth in suitable conditions
Use a freely draining growing medium and a container with drainage. Check moisture and growth before watering. A fixed seven-to-ten-day schedule ignores weather, pot size and seasonal growth changes.
Many aeoniums slow down in hot summer conditions. More water is not automatically the answer to a smaller, tighter rosette or some seasonal leaf loss. The RHS aeonium trial guidance warns against overwatering during hot-weather dormancy. Follow the needs of your identified plant and conditions.
Keep surviving foliage in suitable light and acclimate plants gradually when moving them. Do not move a stressed indoor plant directly into intense sun to force regrowth. Protect tender plants from conditions outside their hardiness.
Propagate a healthy nonflowering branch if available
A leafy, nonflowering shoot is a better candidate for a cutting than an exhausted flower stalk. Use clean tools, allow the cut end to callus and follow species-appropriate rooting guidance in a suitable medium. Keep track of which material is alive and sound.
Do not promise that every cutting will root or that every aeonium can be multiplied from the remaining stump. If the plant has no usable nonflowering growth, replacement may be necessary. That does not mean you missed a secret pruning window.
Distinguish normal decline from a separate problem
The flowering rosette fading while neighboring rosettes remain healthy fits the expected pattern for many aeoniums. Widespread soft, dark or collapsing stems need investigation of roots, moisture and damage. Avoid treating every decline as normal flowering, but also avoid watering repeatedly to revive a rosette that has completed its life cycle.
