Propagation Propagate by seed. Soak undamaged seed in hot for 30 minutes at 40-52°C (104-125°F). Cut a thin slice from the pointed end of the seed. Sow individually in moist sandy compost with the cut end slightly above the soil surface and keep at 20-25°C (68-77°F). Cultivars are propagated by grafting
