Seed collection and propagation

Collect seeds between November and January. Pick the fruits that are soft and purple. These will have hard black seeds inside. It is best to clean the fruit when it is fresh. Place fruits in a bucket of water and rub the fruit gently by hand to dislodge the seeds. Then use a sieve to separate 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. Seeds are non-dormant, viable seed should germinate readily.
