When to transplant Dutch Iris—You can transplant the bulbs while they are dormant, which is typically in the fall.
How to divide Dutch Iris—In the fall, once the foliage has died back, and the bulbs are considered dormant, dig up the Dutch iris bulbs. Inspect the bulbs, separate the viable bulbs and replant them in a new location. Discard any damaged bulbs.
What to do with Dutch Iris after they bloom—After Dutch irises bloom, allow the foliage to die back naturally. This allows the bulb to get the nutrients from the foliage to bloom again the following year.
