Pollen MUST be dry before storage. The steps below ensure the pollen will stay dry, as well as helping it go further. Difficult to spread pollen itself evenly. heh
Take 50x the amount of pollen you have in flour and cook the flour in a frying pan for 15-20 minutes. This will cook the flour while also driving off any excess moisture.
Let it cool.
Mix the flour with the pollen as evenly as possible.
I take 1/4teaspoon at a time, put it in a tinfoil bindle with some rice and freeze it in a thermos for thermal protection. Keep making bindles until you're done. 1/4 teaspoon of the mix will pollinate an amazing amount of flowers.
