Cut the fig in half and squeeze the flesh out into a bowl. It really doesn't matter if you get every scrap of flesh since there are numerous seeds inside the fruit.
Pour water into the bowl and let the fruit soak for 24 hours. Stir it up occasionally so the flesh can become exposed to the water and melt off easier.
Agitate the water and fruit pulp one more time and then pour it through a sieve. Use a very fine mesh sieve to catch the tiny seeds. Place the sieve over a bowl and press the remaining flesh out through the holes with the back of a spoon.
Rinse the seeds in the sieve several times until all traces of the fig pulp are gone. Place the seeds in a bowl of water. Save the ones that sink and discard the ones that float as they are infertile. Let the seeds air dry in the sieve and then plant them immediately.
Fill a pot with half potting soil and half peat moss. Spread the seed on top of the soil and mist well. Place the pot in a warm place with bright light and ensure that the top 2 inches are wet until germination. Germination normally takes anywhere from 15 to 90 days.
