Seed collection and propagation

Collect seeds between March and June. Collecting mature fruits, those that are soft, grey, green-grey to green-red 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.
