Ok...I've got a question for all you pollen daubers! I have read many times that you can store pollen from early blooming varieties to cross with later blooms and you can even ship pollen to trade with other people. So my question is how do you store it? What kind of containers will keep from rubbing off the pollen? Do you refrigerate it? How long will the pollen stay viable? And do you have any other tips you can share?
