What Are Alternative Times to Divide Iris?

Question

We have severely overgrown/crowded iris and they were not divided this late summer/fall. Is it possible to divide them early spring? How much will this affect blooming in the current year? Will they recover from early transplant and bloom well the following year, etc. ?

Answer 1

This is really dependent on where you live. In a warmer climate, those with mild winters, they are normally transplanted in fall. However, it's generally better to wait until spring in most areas, so yours should do fine.
