Propagation seed - cover the seeds with hot water and let soak overnight or until they swell. Pick out those that didn't swell and repeat this process with them. Sow swollen seeds immediately in seeding mix, covering with two to three times their thickness. Do not overwater or allow to dry out and provide good drainage. They should germinate within a few days with this pretreatment.
