Transplanting Iris: When to Transplant Dwarf Iris
Dwarf iris will naturalize and gradually spread, blooming year after year. If they stop producing blooms, it’s probably because they have become overcrowded. Lift the bulbs in summer after the foliage has withered and pulls away easily. Separate them, discarding any damaged ones and store in a cool dry place before replanting them in the fall. Choose a sunny location with well-drained soil.

While many gardeners treat Dutch iris as annual plants and buy fresh bulbs every fall, they will often naturalize and bloom again the following spring. If Dutch iris become overcrowded, the best time for transplanting iris bulbs is in the early fall after the foliage has died back completely. Choose a sunny spot to replant the bulbs and if the soil is likely to become waterlogged, it is advisable to add a layer of compost to improve drainage.

The best time to transplant bearded iris is from July through September. Cut the sword-like foliage back to 2” -3 “, then dig up the rhizomes and cut off the new growths that branch off from the main root.
