Should irises be deadheaded?
Deadheading, or removing the old flowers, keeps the plants attractive and allows the leaves to collect energy for healthy root formation instead of setting seeds. Some irises may bloom twice a year if you deadhead properly. Break off the individual flowers on each flowering stem after they finish blooming.
How do I get my iris to bloom again?
Remove rhizomes from the soil carefully with a garden fork and divide them with a sharp, clean knife so each new section has one to three leaf fans and healthy roots. Replant immediately.

How long can iris bulbs be out of the ground?
The leaves may be trimmed back to about 8 inches, and any long roots clipped to aid in the replanting. Avoid leaving the plants out of the ground for more than a week. Iris do not like competition from other iris or other plants, so keep weeds out.
