I don't think this would work with the irises because I am pretty certain those roots go down and under the blocks, but to get root bound plants out of containers, I just knock the pot all the way around, up the sides of the container and the bottom of the container with my trowel, then tip the plant out. If I am afraid I might break the container, I use one of those rubber type hammers ... I don't know what they are called ... to knock the plant loose from the container. The plants just slide right out.
For me, this works a whole lot easier for all sizes of containers than trying to dig the plant out of the container.

Here's a photo of my iris mistake:
Sure looked pretty, but messed up the bottom of the rose. It used to have to most gorgeous foliage all the way to the ground. I was able to remove the irises, but virtully had to start over with the rose to get it to the foliage back all the way to the ground. When a rose is covered with foliage and bloom all the way to ghe ground, I think it is an awesome sight.
