You accually want to save the pollen..You would remove the plant and cover with a trashbag and kinda rustle it around from the bottom of the plant stalk briskly,a couple shakes is enough.Collect the pollen and keep it dry..Once it gets wet is null and void. Store in cool dry place.Maybe the crisper drawer in the fridge. When you get ready to use it.Just brush one branch,with a little artist brush. You could cross several plants with this technique.On the same plant..Just mark the branches with colored bread ties.
