How to deadhead great mullein

Worth doing?
Yes — more blooms
When
Every few days to weekly through the flowering season — the more regularly, the better the repeat.
Cut
Follow the spent bloom down to the first set of healthy leaves or a visible side bud, and cut just above it. Cutting only the petals off leaves the developing seedpod behind, which defeats the point.

The mistake to avoid

Snipping just the faded petals and leaving the swollen green seedpod below. The plant still thinks it has set seed, so great mullein slows down anyway.
