when would be the best time to divide dwarf iris bulbs ( eg George and Katherines gold. ) They have finished flowering and I want to spread them out a bit. Thanks

I agree, late summer/fall is the ideal time.

These Iris are the very early spring flowering ones Bathgate and die down by the end of April/May usually. In the Autumn they have started putting new roots out.

Thanks. I will do them as the leaves die back as I need to know where the gaps are in this border. They have been in the ground for a number of years and never fail to flower in February.

leave them until the leaves die back as this will allow the bulb to fatten up. then empty the pot or lift the clump and divide then. if in a pot give them a light feed.
if you do them now you will damage the roots and they may not get enough food reserves to flower next year
