Hi Sandra. You can eparate Cereus peruvianus seeds from their pulps the same way you do tomato seeds. Place the seeds in a water bath and let them sit for a week or two. The water will get smelly so I usually cover the bowl with plastic wrap. What happens is that the pulp begins to break down and to ferment. When you see the foam, you can rinse the seeds several times in clear water and the pulp material will separate from the seeds and float away. If it doesn't separate easily, you can gently rub the seeds between your hands to help it along. The seeds being heavier than the fermented pulp will remain in the bottom of your bowl. After separating, dry the seeds thorougly on a towel and store in an airtight container in the refrigerator. They should remain viable for about a year this way. Cheryl

Hi Cheryl,

Thank you very much for your input. I shall try your method next time and see how it works. The pulp collected should make my worms happy (vermicompost). :)

Have a great day!

Sandra
