Here in East Texas, bearded irises (Iris x germanica) are a favorite pass-along plant to share with friends because they are easy to propagate by division.

In order to keep irises healthy and happy, it is usually recommended that they be divided every three to five years. This encourages the plant to produce an abundance of blooms. September is the best time to dig, divide and replant the iris rhizomes. However, later fall is also a good time. Just follow these four easy steps:

Step 1: Working carefully around the clump with a fork or spade, dig it up and shake off as much dirt as possible and cut the foliage back to about one-half its length.

Step 2: Pull the rhizomes apart or cut them apart with a sharp knife. Be sure each division has some healthy leaves attached. The smaller rhizomes on the outside of the clump are the most desirable to replant.

Step 3: To help with later identification, write the name on the leaves with a Sharpie pen.

Step 4: Pass along some of the iris rhizomes to friends, and plant others in shallow troughs in full sun and well drained soil. Do not cover the rhizomes completely with soil. Remember to water after planting every other day for at least 10 days because we are still in the heat of the summer.

Now, wait until spring when the irises reward you by producing showy flowers in many beautiful colors.
