Seed collecting:
Collect mature fruits either by breaking off individual spikes or by removing plants that are drying off with fruits that are purple to straw-colour and seed segments coming apart easily.
Seed cleaning:
Place the fruit spikes in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruit spikes with a rubber bung to dislodge the seeds. Use a sieve to separate any 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.
