I placed some bearded iris seeds in moistened commercially produced starting/potting mix at the end of January and placed them in the refrigerator. Per some instructions I had found on YouTube, I allowed them to sit in the fridge for about 6 weeks. I then took them out of the fridge and I've placed them in a sunny, but coolish window. The temperature in the window is typically around 50-70°F degrees with an average of around 65°F. I do try to keep them watered based on how moist their soil feels.
So far, I haven't gotten any sprouts at all. In a few areas, I have tried to dig up a seed or two and I have not seen any signs of sprouting.
How long should I wait for signs of sprouting and are there any things I can do to encourage sprouting?
