Dusty Miller Plants
My Dusty Millers are very big on each end. They do very well where I have them but they seem to be overgrown and lots of yellow flowers or blooms. Should I trim them back and discard all the blooms? I do transplant sometime and they do very well. Some the smaller ones also have a lot of blooms.

If the plant is leggy or simply needs rejuvenation from last year's growth, trim it down to new growth (but no more than a third of the plant). Most actual pruning of this plant takes place following its blooming, of which you can cut it back by a third.
