Due to all the excess rain we have had in Oklahoma City my irises are now rotting off at the ground. All the green leaves are turning brown and rotting off. Will this kill the tubers for next years blossoms. What can I do so that I don't lose my heirloom irises?

If they are sitting in constantly moist ground, you might need to move them to an area that has better drainage. These are bearded iris, right? I got the following from http://home.cinci.rr.com/hiddenacres/:

Culture of Bearded Iris
Bearded iris are among the easiest perennial plants to grow. They can be successfully grown in most of the continental United States, with the exception of Florida. They need approximately six hours of direct sun and to be planted in well-drained soil. Irises benefit from moisture, but do not like "wet feet". They will benefit from a light feeding with a low-nitrogen organic fertilizer about six weeks before bloom. Little is needed beyond these requirements and normal good garden practices, such as keeping weeds to a minimum.
Your new rhizomes should be planted between 18 and 24 inches apart. They may be planted closer together, but this will require more frequent division. The proper planting depth varies somewhat depending on climate and soil type. Dig a hole deep enough to accommodate the rhizome and roots. Form a mound of soil in the bottom of the hole and spread the roots out over the mound. Cover with soil until just the top of the rhizome is exposed and firm the soil around the rhizome. Areas with lighter or sandier soils and hot climates may plant the rhizome slightly deeper.
Irises need dividing every three or four years, or as clumps become crowded. Most newly planted iris should bloom the first spring after planting. The best bloom will be the second and third years. After this, the irises will have multiplied to the point of overcrowding. Simply dig out the clump and cut into sections similar to the original piece you received. Replant the rhizomes and begin the process again. The accepted time to divide bearded irises is six weeks after bloom ends.

I added the text in green!

My concern is that because of all the excess rain - their feet were standing in water - no way around it - and now they are rotting - is there any way to save them now?

Can you dig them up and store them until it dries out?

Because of my disability, I am not able to dig them up - but we are starting to dry out and I am hoping that this will be the end of the humongous rains for a while - and I won't lose all of them.

I divided my iris some time ago & the ones I transplanted are rotting also. The old bed seems to be ok. Strange, b/c I felt the new bed had better drainage. At least I still have the ones in the old bed.
