In this how-to video, you will learn how to divide and re-plant irises in your garden. First, dig out the iris. Clean out the old, dead leaves and take the dirt off. Trim the leaves off as well. Break off the pieces, as these can become a new plant to grow. Several pieces can be broken off, allowing you to grow even more irises. Discard the part that is left over. You can save the pieces for a little while, but it is better to plant them soon. Irises do not require a rich soil to grow, so keep this in mind. Do not plant them too deep. By viewing this video, you will be able to divide and re-plant irises properly.
