After the flowers have turned brown and leaves have fallen. Trim before new growth appears.

I live in Ireland and I wait until the Spring when all frosts are gone. Then I cut out dead stems. I like to keep the bushes small with big heads so I cut above new growth lower down the bushes. So far I have had success doing this.
