Hi folks

I totally neglected my butterfly bush last year. Now I have beautiful
blooms, and I look forward to a gazillion Monarchs soon (I am right on
their east coast migration path) but I also have a bunch of dead
stalks from last year. Can I prune them off now? Should I wait till
Fall? Advice needed, thanks all!

Sure, cut off all the dead and even some of the live new growth if you
want to shape the plant - Buddleias usually respond favorably to pruning
most any time of year. Also deadhead the spent blooms to encourage more.
