Passiflora quadrangularis seeds should be pretreated with a light scarification from sandpaper or file which significantly reduces germination time as the seed coat is hard. After scarification, soak the seeds in warm water for 24 to 48 hours prior to planting. Plant the seeds ½ to 1 inch deep in a well draining potting mix. Plant the seeds at least ½ inch apart from each other to prevent overcrowding. Keep in high moisture and humidity but make sure the soil does not stay soaking wet. Ideal germination temperature is between 60°F to 85°F. Germination typically takes 10-21 days with pretreated seeds. Seeds without pretreatment may take months to germinate. Even with optimal conditions, germination may be slow and sporadic.
