I read to trim weigela after blooming. Does that mean after blooms no longer exist

Question

Bush is no longer in the process of “blooming” but still has some existing blooms

Answer 1

This will mean after the blooms fall off, or start to fall off. You don't have to deadhead them all at once. You can cut them as they start to degrade, one or a few at a time.

Alternatively, you can wait to cut them after they stop blooming completely, if you wish, as long as you can deal with some unsightly blooms.
