Seed collection and propagation
Collect seeds between September and March. Collect maturing fruits, those that are large and turning green-yellow and with hard seeds inside. Place the fruit in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required to remove all the flesh. Then spread the wet seeds on some paper towel and leave to dry. 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. From one collection, the seed viability was high, rat 100%. Seeds are non-dormant, viable seed should germinate readily.
