Great looking mums Jennifer, I posted some photos to the what's blooming thread before I saw this, but will post some closeups here. I try to pinch mine back by at least a third 2 to 3 times in Spring. Somewhere I read that they should not be pinched later than Father's Day, but I would think that would vary by where you live. Most of my current ones have returned for a few years now and been divided. It seems like it's the years with a warm spell followed by a hard frost that kill most of mine. This year grew some divided ones in pots and sat them out in front to add fall color. Think I'll do more like that next year.
