Seed collection and propagation
Collect seeds between August and December. Collecting mature fruits, those that are soft, green, light-green to cream-white or black and have a hard woody seed inside. Place the fruits in a bucket of water and rub with your hands to remove the soft flesh. Remove any seeds that are floating. These will be empty seeds. Drain the water and keep only the hard seeds at the bottom. Place the seeds on 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.
