Siberian Iris Overwintering

Question

I live in Alberta, approx Zone 3 growing conditions, and wondered if Siberian iris plants should be trimmed back for overwintering. I know the other types of iris are often trimmed back to approx 3 inch in height, but wondered if same applied to Siberian iris. Thanks!

Answer 1

Yes, Siberian iris foliage should be trimmed back for the winter, but only after the foliage has turned brown. Then trim back to about 2 inches in height.
