Collect the pollen over time and place it into a clean vial like a film canister. I really like using a paper plate held under a group of flowers, and then gently thumping the stem. After collecting the pollen, the paper plate can be creased, held over a vial, and the sides and edges thumped until all the pollen is vibrated into the vial.
For a pollen carrier, heat about 2 or 3 teaspoons of flour in an oven to 180F for about 20 mins or in a small pot set on low heat, let it cool *thoroughly*, and mix with the pollen to dilute it. I use a ratio of about 1/4 tsp pollen to 3 tsp flour and have very successful pollination rates. Store in small containers like contact lens cases excluding as much air as possible and store in the fridge for long term storage. Remember, it only takes one male to fertilize one female ovule, and there are millions of pollen cells in a 1/4 tsp of pollen so be sure and dilute it.
Take out only enough of the pollen mixture (1/4 tsp.) to use for one session and use your finger, or a small artist brush (my preferred method) to pollinate a few of the lower branches which have fresh, white pistils. Do not contaminate the main pollen source with a resinous, sticky artist's brush! Clean the brush's bristles with Isopropyl alcohol after each session and let the bristles dry thoroughly before using it again. I hit the chosen receptor branches 3 times on a weekly basis to insure a good supply of seeds.
*Label* the pollinated branches, and harvest your seeds in 3 to 6 weeks. I just cure the seeded branches with the rest of the crop, and tear apart the seeded buds with my fingers. You'll find the seeds close to the stem. Store the seeds in the fridge or freezer, labeled of course, with a little dessicant like heat treated rice for long term storage.
