How I do it-dividing irises:

Above is an over crowded clump of irises that obviously needs dividing.

First, I dig out the clump and remove as much of the dirt as I can, without causing too much damage. (Notice the umbrella stand.)


Next, using a clean, sharp knife, I separate the growing rhizomes from the spent rhizome.

This picture shows the growing rhizomes and the spent rhizome, the plant that bloomed this spring that has long since lost it’s leaves.


Last, I replant 2 of the divided rhizomes and put the remainder in a cool dry place until sale. I replant Two because they fill out faster.
