Beginner Gardening: Something Growing with Irises, 0 by poinget

I separated them. With a lot of jostling, I loosened the dirt and the big clump fell apart. I then noticed the difference between the irises and these NOIDs. Now I know that in the beds I had thought were predominantly iris, actually consist mostly of this unknown plant. You are right. These plants choked out the irises. The iris rhizomes were partially rotted. I cut those sections off and replanted them. I moved the other plants to another area to see what grows.

Pic 1 is the bed now. How does that look? (I uncovered a few new irises that were no more than 2 inches long underneath the leaves piled on top.) I didn't follow the advice to point the fans in the same direction (I learned that last night) as most of those I had replanted months before and I didn't want to move them again just as fall approaches. And should I wait to move the baby irises? (pic 3)

Pic 2: I ended up snapping the rhizome in half and planting both pieces. Was that the right thing to do?

So many questions! I appreciate the thoughtful answers. Thank you!
