Thanks for your ideas, Shirlee. I've almost given up on storing and using frozen pollen ... no luck over two summers of trying it. I think my troubles arise at the drying stage, and impatience (or lack of attention) in waiting on it to dry. No matter what I've tried all the crosses I did with frozen pollen resulted in no pod or pods that quickly turned black. So, maybe I will try out the refrigerator idea ... it sounds a lot easier to collect pollen and pop it right into the fridge, and maybe easier not to miss that crucial window of time when it dries and fluffs up? What would you say was the window of time from start to finish on having the pollen in the fridge?
