Iris - Knowledgebase Question

Lawrenceville, Ge
Question by jackandmarie

We transplanted about twenty five iris plants from a previous home about 9 years ago to our new home and they have never bloomed.

My husband planted them in partial shade. Should we dig them up and replant them in full sun and what time of the year should we do this?

We live about 25 miles outside Atlanta, GA in Lawrenceville, Ga.

Thanks for any help.

If your irises are not blooming, they are either not getting enough sunshine, or they are overcrowded. Typically they will bloom in about 4 hours of sunshine. If they are getting less than that, move them to a sunnier spot. If they are already getting at least 4 hours of sunshine, simply dig and thin them out so each rhizome has lots of room, and then replant in the same bed. You can do this now, in spring, or in late summer after they have finished blooming.
