Germination: Soak the Psychotria viridis seeds for about 15 minutes in a mild bleach solution (2 Tbs bleach in a cup (8 oz) of water). This will help keep them from molding during their long germination period. Rinse and soak the seeds in clear water for 12 hrs. Plant seeds in potting soil about 1/4 inch deep (8 mm). Put the whole pot in a ziplock bag for mini-greenhouse effect. Keep the temp around 70-80 degrees F. (22-28 degrees C.) Keep out of direct sun. Be patient! It can take as little as 6 and as many as 16 weeks for germination!
