It takes a fairly good period of drying out (two weeks should do it) after digging up for the old corm to shrivel up and give way. I haven't grown glads for a while, but after digging them, I'd clean all the dirt off, cut the foliage down to about a 6-10" fan and just leave them in a bucket till they were dry. When totally dry, the old corm came away from the new one with just a twist of the wrist. Too green and they stick tight.

Whether or not they bloomed, your glads should have produced a new corm and probably a lot of little cormlets.
