an Iris question

Usually the reason bearded iris do not bloom is:
1.   Not enough sun, they need 6 hours of full sun a day)
 2.  Overcrowding, they haven't been divided in several years and have grown 
rhizomes all over each other 
 3.  Being planted to deep in the soil.  The top of the rhizome should be 
exposed to air and they need plenty of air circulation.  They do not like other 
plants crowding them or covering the rhizomes, it is not a good idea to have 
any pretty ground covers growing over them.   Do not mulch them.
It doesn't sound like it could be the first 2 reasons but these three are the 
only ones I can think of now.
Maybe Chad (another iris grower) can think of more and will respond.
