Ok gang, I have been doing some research on this.
Previously, I mentioned some observations I had with bloomouts and others mentioned they also noticed one of the same things; There were hardly any roots if at all.
The other day I received the book of many iris answers: THE WORLD OF IRISES.
In chapter 21 on page 314, Ben Hagar wrote about Culture and Propagation of irises.
He mentions under Root Growth Cycles that the rhizome has two root growth cycles. The first is when the rhizome begins to send up a bloom stalk. Around the same time, it begins sending out new roots, and the old roots decay away. Up until that time the plant has been using the nutrients that were stored in the rhizome.
At that moment it dawned on me that the bloomout rhizomes I have observed seemed to have missed their cycle of root growth for some reason. The old roots decayed away alright, but the new roots never started growing. With very few or no roots to supply the plant with nutrients to send up a bloom stalk and increase, the plant must continue to supply nutrients stored in the rhizome until it about exhausts itself and inevitably "blooms out".
That is the theory my mind conjectured anyway. What do you think?
Furthermore, if that is true, then Anner's suggestion to put some root hormones on the rhizome would make sense.
I wonder however, what would cause the rhizome to miss its root-growth cycle?
