Seed collection and propagation
Collect seeds between December and February. Collect maturing fruits that are fat and turning black, by running your hands along the fruit-spikes. Place the fruit in a tray and leave to dry for 1 to 2 weeks. No further cleaning is required if only fruits were collected. If collected with other material, use a sieve to separate the 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.
