On this same line, I've always been curious how long the pollen stored in freezer would be good?
For my pollen dabbing, I'm a lazy gardener with too much work. I use a 7-day pill box container to harvest the pollen. I fill a cotten swab with as much pollen as possible and use that for pollenating. I cut the cotten swab in half or shorter so that it fits in the pill box.
