Seed collection and propagation
Collect seeds between September and December. Collect fruits that have started to dry and turn pale. Check for viable seed inside the fruit before collecting. Spread fruits in a tray and leave to dry for 1-2 weeks. No further cleaning is required if only fruits are collected. The seed can be stored in the fruit or cleaned further. Rub the fruit gently by hand to dislodge the seeds and use a sieve to separate unwanted material. Store seeds in a dry cool place.
