Cambridgeshire, United Kingdom
I'm currently struggling to break up a large clump of irises that I believe have been growing in the same place for about 25 years and the clump is virtually a solid lump of virtual concrete. My aim is to separate individual plants and replant about 3" apart to form a new clump having dug the area over and incorporated plenty of compost. . A point of interest is that the flowers are the usual colour and quite small but rather than the rhizome which my other irises have, these plants have what appear to be small bulbs at their base and presumably need to be planted normally.
Does the small flower size and the root type give any clue to their identity?
The main thing I wanted to check with you is whether it would be a good idea to cut the leaves down to a feww inches to relieve the load on the roots while they establish themselves?
