I injected the pollen in the opening at the bottom of the fig after worming the tip of a plastic 12cc syringe and part of a large hypodermic needle up in it. I used another smaller hypodermic needle stuck through the side of the fig to relieve the air pressure. After injecting the pollen in, I put some duct tape over the opening. The figs changed color and began to swell within a week. A week later they ripened. The other figs on the tree show no signs of ripening although they were the same size as the ones I tried to pollinate. A few seeds from these figs sank, but not nearly as many as some of my other attempts earlier in the year.
