I soak iris seeds in plastic sandwich bags with frequent water changes for
about 3 weeks. Then I drain the bags and refrigerate for 6
weeks. It has worked fine for Japanese, Siberians, Pseudacorus, Setosa,
Laevigata, and Chrysographes.

In the British Iris Society's booklet on growing irises from seeds, it says
that seeds should not be submerged when soaking, just placed in a very shallow
layer of water with their tops exposed to the air. It says submersion will
kill the seeds.
I've not seen advice like this anywhere else, and it
doesn't seem consistent with some other methods I've read about, like
suspending a mesh bag of seeds in the tank of a toilet or leaving seeds in
flowing water for extended periods to leach out germination
inhibitors.
I soaked seeds for the first time this year, submerged in
small jars for five days with daily water changes.
Any thoughts on
this? If you soak seeds, what is your procedure?
Thanks,
