The Q&A Archives: Old Irises

Question: A friend thinned out her irises last year and gave me some of the rhizomes. I didn't plant them last year and still have them - can I still plant them this fall or are they ruined? I really hope there is some way to save them if I can.

Answer: If the rhizomes are still in good shape, not moldy or mushy, you could plant them this spring. Many bare root iris are stored commercially and shipped for planting in spring, so it is an accepted practice to plant them then. It is better to plant them in the spring than to keep waiting, the longer they are out of the ground the more chance of them not surviving.
