Seed collection and propagation
Collect seeds between January and December. Collect mature woody fruits that are greyish-brown and not split. These will contain seeds. Place the woody fruit in a tray and leave to dry until it splits open. Fruits can be placed in the oven at low temperatures to achieve the same result. Place the dried fruit in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and 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 without pre-treatment.
