To properly perform iris replanting, start by digging up the iris rhizomes in late summer or early fall. Trim the leaves and roots, then replant the rhizomes in well-draining soil with plenty of sunlight. Make sure to space them out and plant them at the right depth. Water them regularly and fertilize them in the spring to promote healthy growth.
