You can soak the seeds in tepid water for an hour up to 12 hours keeping them out of direct sunlight. Sometimes you will see which ones have imbibed because the seed will noticeably enlarge. Pot the imbibed ones no deeper than 1/4 - 1/2 inch. You can nick the seeds coat that have not imbibed using a fine file or nail file and then continue to soak in water for another hour. You can then pot them and say a prayer.
