Though it hasn't been a problem for me personally, I thought it might be interesting to see which members that have had experiences with bloom out. The question is if it possibly is climate related and if it is a larger problem in warmer areas? So it would be helpful if we had lots of participants.
So what is bloom out? I found this description in an AIS blog:
"The rhizome increases in size and twists slightly as if it is pushed out of the ground. This could be the result of the roots drying out. Some of the "lightbulbs" bloom. The bloom stalk comes up in the middle of the fan and dies back quickly. The rhizome eventually dries up and dies also."

I'm curious if anyone has noticed that "The rhizome increases in size and twists slightly as if it is pushed out of the ground."?
Possible solutions:
Covering the rhizome with soil or an upside down pot. Question is, does this work and how often is it effective? In some soils and climates this could make the rhizome rot, so obviously one would need to have that in mind before trying.
Cutting the bloom stem. Does this have any effect? Is it better to cut the bloom stem early or perhaps even to cut the fan before any signs of bloom, to conserve energy for new increases?
Possible preventive measures:
In warm climates, is there a chance that deeper planting prevents bloom out? The idea here is less stress, less heat and therefore less bloom and more increases.
So let's see if we can get a discussion going. I realize this isn't a topic with a huge appeal to everyone, but at the very least we perhaps can gather a little info in one place to make it easier to find.
