Moving Iris in the green

Has anyone successfully moved iris that have just finished flowering and still have their green leaves? I am impatient and want to move some miniature iris before they have died down.
The big bearded irises benefit from having the foliage cut right back, by about half, to make it easier for them to establish. If you move them at this time of year, there isn't usually any, but the other thing to look out for is wind rock. They're tricky to keep in place when moved, so it can often help to put in a couple of little twigs/canes etc to keep them steady. All depends on weather conditions and where they're going too.
The little irises don't normally cause any probs at all GD, but they don't keep flowering year after year like other bulbs. They diminish after a few years.
A lot of nonsense is talked about moving peonies, but they can be easily moved if you're careful. Don't bury the crown too deep - no more than about an inch below soil level, and shallower if you have heavier soil or lots of rain. Nice free draining soil, and as sunny a site as you can get. Big a rootball as possible, and have the hole ready before you start, so that they have minimal disturbance. I wouldn't do it just now though.
I live in west central Scotland - not where that photo is...
