Seed collection and propagation
Collect seeds between November and January. Collect mature fruits, those that are fat and turning red with brown seeds inside. Break open the fruits and wash the content in water. Drain the liquid leaving behind the seeds. Place the wet seeds onto paper towels 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 is usually high. Seeds are non-dormant, viable seed should germinate readily without any treatment.
