Dividing Iris As everyone who raises iris knows, sooner or later you have to divide your iris.   Here are a few pictures of that process This is a clump, ready to dig Here is that same clump, lifted from the ground and washed so you can see how the rhizomes connect together. This is that same clump, split apart.  There are 7 rhizomes to replant and 2 spent bloomstalks to throw away.   This is a picture of one of the rhizomes, still wet from being washed.  See the "babies" along the side?  This one is ready to have it roots and foliage trimmed so it can be replanted.
