Tall bearded iris (Iris 'Immortality') should be pruned annually in late summer/early fall. Cut back the flower stalks to about 8 inches (20 cm) above the soil. This will encourage healthy new growth. Trim away any leaves or dead flowers which have died back. If you want to maintain a tidy appearance, you can also prune out any foliage that looks scraggly. In some climates, a second, light pruning can be done in early spring to remove any dead foliage or flowers.
