When Is The Best Time To Transplant Iris

roots?

The best time to transplant your iris is when the soil temperatures are in the 70’s and 80’s, which is spring and fall. The reason for this is that if you wait until summer or winter when it gets too cold, then the rhizomes will be dormant and not growing at all. You can plant them anytime of year as long as their roots have been cut back so they won’t get any bigger than a pencil eraser!
