If plants are growing at the same time, you can chop a branch of the male that has lots of pollen pods that are opening, and put it in a wine paper bag. The long narrow ones. And put the bag over the girl branch you wanna pollinate. And tape it shut. Come over and shake the bag when you are in the garden to make sure they mix. Some say leave the bag on for 24 hours. I leave mine on for three days. Make sure rain ISNT in the forecast.
When you take the bag off, mist the branch with water, so the pollen left on the branch is killed. I learned this one the hard way. If you don't, the wind takes that pollen and gives it to other plants.
This year I am trying a pollen collector technique I just found. I saw a method using a tray under the plant to catch pollen, and a clear bag with holes on top of the bag, to keep it from pollinating anyone else. Shake the plant to help the pollen drop, and it collects on the tray under your plant. I have a couple desicant packs from shoes I will put in the pollen jar, to keep em dry. We'll see how this way goes.
I hope any of this helps.
