trying to find out how iris seeds are graded. Unsure is #4 is larger than #6 or is it smaller.
Rhizomes are graded by the number of growth points or eyes they have. So the #4 would have 4 eyes and the #6 would have six eyes. More eyes will give you more stems, foliage and flowers.
look healthy but I haven't seen one flower. I've had them about a year now.
They are being moved too much. Put them in a full sun location and leave them. They bloom in spring. When moving or planting, do it when they are dormant in late summer to early fall. They may not all bloom every year. Most of them will, though. Also, be sure they are planted with the top of the rhizomes above soil. They like to bask in the sun.

I have tall and short bearded iris plants of various colors, all in one bed. I wish to move them and spread the colors further from each other than clumped all together in one spot. How do I make sure I have the colors right after they have bloomed? Is there some way to mark the plant? I live in extreme south west Minnesota between South Dakota and Iowa. Is your advice of planting them soon after they bloom the best time, or in the fall, which is when most people here say to do the transplanting? Thank you!

As for when to move them- The end of summer into fall will be the best time. This will give them adequate time to establish before winter, while not being too hot to acclimate. Here is an article that will help:

I cut the foliage from my bearded iris too early. Is there anything I can do to assure that the plants bloom next year?
Just carry on with their regular care. Here are growing tips:
ly two - is that sufficient for the season? I live in southeastern PA and have a returning borer issue every year. I have been using Bonide's Captain Jack Deadbug product for awhile, but perhaps not with the best timing or frequency.I also have dug up and thrown out infected plants.
Pesticides contain instruction pamphlets on the bottle. These should be read, thoroughly, and understood before using the product.
Different plants have different requirements, but be aware that tree borers, once inside the tree and established, can be near impossible to get rid of.

Once Iris flowers bloom should you dig out the rhizomes and store away for following year.They are planted in a huge pot on my patio.
No, doing so will likely kill the plant. They need to keep their leaves in order to store energy for the next year. They are, fully, hardy throughout the united states.
Simply remove the bloom stalk, and leave the plant to continue on.

. Should I go ahead and plant them? I see online that the y should be planted in the fall. So how do I store them in the meantime?
You can plant them now. Iris are dormant in late summer to fall and that is the best time to divide and replant.
