Cosmos is usually planted in the ground rather than in pots, and it is an annual herbaceous plant in most regions. Some flower enthusiasts have asked whether it is necessary to prune cosmos after flowering. If it is planted in the ground, there is no need to worry about it, because cosmos will produce seeds after flowering, which will then naturally scatter and germinate new cosmos the following year.
However, if it is a potted cosmos and you do not want to keep seeds or only keep a small number of seeds, in this case, we can cut off the spent flowers after flowering to avoid the nutrients consumed by seed production as much as possible, focusing the nutrients on letting it continue to bloom. If you want to keep a few seeds, you can retain some of the spent flowers to produce seeds, and cut off the others.
If you do not want to keep any seeds at all, you can simply cut them off after the flowers fade.
Although it is not necessary to prune cosmos after flowering, since the nutrients in potted cosmos are not very abundant and cosmos will continue to branch out and bloom, it makes sense to avoid excessive nutrient consumption.
