Re: CULT: when to move bearded iris?

Suzanne--you'll probably get a lot of answers, but here goes anyway--the
only part of the iris that need cutting back after blooming is the spent
bloom stalk--just cut it all the way down to the rhizome.  The plant needs
all the leaves it has to keep producing food for itself as it gets ready for
summer dormancy, so don't cut those.  You can remove dead leaves anytime,
