Planting Stored Iris Rizomes

Question

I just received iris rhizomes that we’re divided out of my late grandmother’s garden in Arizona. I live in Washington and the weather forecast predicts freezing weather this week. I’m planning on storing them over the winter. When is the best time to plant these stored rhizomes?

Answer 1

You can let them dry out then store them in newspaper to keep them separated. Wait till spring to plant them after all chances of frost have passed.
