Seed collection and propagation

Collect seeds between April and July. Collect mature fruits, those that are fat and hard. Place the fruits in a tray and leave to dry for 1-2 weeks. No further cleaning is required if only the fruits are collected. If with other materials, 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.
