Reblooming Iris Notes
Reblooming Bearded Irises grow faster than regular irises, so unlike the standard bearded iris, you'll need to divide them more often. To prevent overcrowding, divide re-blooming iris every 2 to 3 years, take only the outside rhizomes of the plant. Leave the healthy older portions of the plant intact. Replant the small rhizomes 12 to 18 inches apart.
Rebooming Bearded Irises are not always guaranteed to bloom. It often depends on geographic location, soil, and climate conditions. Reblooming Bearded Irises can also vary from year to year. They are heavy feeders, requiring a little more water and fertilizer because they need an extra boost to flower again. Re-bloomers require a little more care than the standard bearded iris but are worth the effort.
