Iris bulbs?

[lady topaz]

Hi,

Just about to dig up a load of bulbs now that the flags have gone over. They have spread too wide and I want to consolidate them again.

I have been told to just replant in a group. I have also been told to dry bulbs off and replant next year. Is there a definitive method please?

There are 2 groups of irises, those with bulbs that die down each year after flowering and and those with rhizomes that stay in leaf.
Flag irises are usually the latter. See here for dividing. http://www.gardenersworld.com/how-to/projects/prop...
If you mean bulbous irises, then once they have died down, you can store the bulbs and replant in autumn.
