Seed collecting:
Collect maturing pods, those turning pale brown with hard seeds inside. Be gentle with the pods as they split open easily.
Seed cleaning:
Place the pods in a tray and cover with paper to prevent seeds from popping out and leave to dry for a week. Then rub the dried pods gently by hand to dislodge the seeds. 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.
