And make REAL sure you get all the "original" iris out of the ground ! The actual "roots" are alright to leave....but even a pea sized chunk of rhizome CAN, and likely WILL grow....then, you end up with a "mixed clump" ! I always watch the area very carefully for a month, or 6 weeks after replanting....and quite often see a little "grass -blade" sixed iris leaf coming up.....from one of those "pea-sized' chunks that I missed !
