Do you need to cut the dead flower off of King Protea as the new one is growing beside it?

Question

The dead flowers are still there but see new ones coming beside them; is it necessary to do this?

Answer 1

Yes, cut the flowers off of King Protea including some of the stem, but avoiding the new flower buds. Do not prune stems that don't have flowers because they will be next year's blooms.
