Seed collecting:
Collect mature woody fruit that are greyish-brown and not split. These will contain seeds.
Seed cleaning:
Place the woody fruit in a tray and leave to dry until it split 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.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
