Seed collection and propagation
Collect seeds between November and January. Collect ripening fruits that are turning yellow and containing a hard black seed. Place fruits in a bucket of water and leave to soak overnight, then rub the fruit to remove the flesh. Rub and change the water a few times until all the fresh is removed. Leave the cleaned seed to dry and then store with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily.
