It's best stored after dessication in order to remove a lot of it's moisture. You can buy or build a dessication chamber which range from complex machines to a simple large jar with silica gel.

After dessication it's best stored sealed in a near-air-tight container and inside another container. Small petri dishes (with covers) sealed with parafilm are excellent for this...then into a piece of tupperware (or similar).

After that it's into the fridge or freezer.

1-2 years of good storage this way.

If you want something a bit more low-tech and you're planning on a shorter storage time then you can collect tassels or knock a bunch of pollen off a tassel into a paper bag. You need to store this in consistently dry place without much moisture/humidity and give it time to dry. Once dried out it's generally good for a few weeks to a couple months without losing too much effectiveness. This method is a bit less consistent, but it's generally a good one if you have a quick turnaround for the pollen use and you can get the tassels/pollen dry + keep it dry.

Awesome! Thank you so much for the detailed answer. I will try my hand at the low-tech solution and report back with how it goes. I think here in AZ drying it will be the easiest part. :)
Thanks again for your help nc-crn!
