Seed collection and propagation
Collect seeds between January and December. Collect fruits that are maturing, fat and hard. Place the fruits in a tray and leave to dry for two weeks. Then rub the fruit gently to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
