Question

When can I cut the dried up bloom bulbs off my peonies?

Answer 1

When they're done blooming, prune bloom and stem, leaving leaves intact to manufacture next years food.  The bushes stand upright and stay green most of the summer adding a nice backdrop for other blooming plants.

Answer 2

I do it as soon as they are done blooming.
