Deadheading does indeed promote bushier growth; it also encourages blooming. You don’t need to restrict yourself to the center bud. Examine the plant and get rid of any flowers on the wane and edit a few unopened buds–this may seem counterintuitive, but it works! Regular deadheading ensures a longer blooming season. (Be sure you pluck spent flowers before they have time to go to seed.)
