Chelsea flower show.

If you put them in a pot at least you can guarantee that the rhizomes can be allowed to see the sun without being overshadowed by other plants. I have one space which I try to keep, for iris only, because of the problem of letting the rhizome get the sun on them. If I plant them amongst other perennials they do stop flowering.

Thats interesting, I originally planted then in open ground to baked by the sun but other plants have gently surrounded them and I thought they were being protected by them. Maybe just a little too much then. I will have to re- consider where to plant then this autumn. Thank you.

I lost almost all of my iris until a friend told me why. You can move them as soon as flowering is over. Cut the foliage in a spear head shape leaving approx 6"of leaf. Dig up the rhizomes cut off excess roots and rotten looking bits of root. Replant immediately in your pot to let them get growing as soon as possible. The top of the rhizome should be clear of the soil.
The link below is a good one as Kelways are among the top growers of both Iris and Peonies http://www.kelways.co.uk/useful_information/beardless_iris_care/10/
