Last autumn I collected and brought in many iris seeds, before winter got cold I took them out and scattered them on the surface of soil in seedling trays sat in the pond. It was a mild winter here and there have been only a couple of night time frosts, 1/4 of ice would be the deepest ice seem this winter.
The seeds have yet to germinate, they are wet as the soil is soaked.
Should I lift the seeds and bung them in the fridge or freezer for a few days? I had hoped nature would do the trick but seamingly not, or is it still too early?
The fridge will probably be 4C 40F, the freezer ... below 0C 32F. I could turn the fridge down a bit more or put the seeds in the cold compartment which will be only slightly below 0C 32F.
