They were just small plants with not much root anyhow. I will not be planting anymore in the fall, I don't think that is a good idea. I learned with iris to plant them in the early summer immediately after flowering. Most vendors sell iris in the fall and I hate that. It's too late to plant and they can't establish and heave and lay on the wet winter ground and either dry up or rot. My last yard had lots of looser compost soil and my dl did not heave. So I am inclined to think the heavy soil contributed.
