When to Transplant Iris. The best time when to transplant iris is in the summer, after the iris have finished blooming, up until fall. Steps for Dividing Iris Plants. To divide your iris, start by lifting the clump of iris plants out of the ground with a spade or fork.
How Often to Divide Irises. Lift and divide Irises when flowers appear overcrowded, which is about every three to four years. You can watch for signs, such as a decrease in bloom quality and amount of blooms. If you do not divide crowded plants, it restricts air flow, making them more prone to foliar disease.
