Seed collection and propagation
Collect seeds throughout the year. Collect ripe straw coloured fruits, check that they contain viable seeds. Fruits can be collected directly from the bush or from the ground underneath. Remove twigs and other plant material. Place the fruits in a tray and leave to dry for one to two weeks. No cleaning is required if only the fruits are collected. The seed can be stored in the fruit or can be cleaned further. Rub the fruit 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. Seed viability can be high but seed availability can be low.
