Seed collecting:
Lift branches carefully to locate the fruits. Collect berries that are reddish and soft, with a hard seed inside.
Seed cleaning:
Place the berries 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.
Seed viability:
From one collection, the seed viability was high, at 100%.
