Seed collecting:
Collect whole plant with maturing capsules, those that are fat, drying off and contain brown seeds.
Seed cleaning:
Place the plants in a tray and leave to dry for one to two weeks. Then rub the plant especially the capsules gently by hand to dislodge the seeds. Use a fine sieve to separate the unwanted material. Be very careful as the seeds are very small. 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.
