I have an unruly bush. Some of the stems are quite long. Do I trim now or after they bloom ?

You should trim right after blooming. They bloom on old growth. So if you trim in late winter or early spring they won’t bloom as well as the buds are trimmed off.
Thanks, I guess that trimming job will wait.
See if this helps you.

As a general rule, trimming or pruning is performed after blooms fade.
Hello -general rules suggest to prone after flowering in most cases and never take more than 1/3 of the plant.
My neighbor just proved thiers recently it was growing into the roadside. You might suffer some lack of blossoms doing it now but if it’s a healthy large existing plant probably could tolorate some mild pruning now.
