Are the corms on this bearded Iris big enough to divide? I have just separated some of a similar size, using a sharp knife. They had very substantial roots, and I've added some bonemeal and cut back the foliage.

Probably the most important part of the division is depth of the fibrous roots underneath the tubers/corms. A test dig at the side will help uncover whether they're substantial enough to go ahead without killing 'em of.
They certainly look good enough on the surface.
Thanks they are like elephants trunks so i'll divide now
