The average germination time for Stemmadenia littoralis seeds is 2 weeks.
Soak the clean seeds in hot tap water until they begin to swell. Change the water two to three times per day. Do this until the seeds begin to swell.
Once the seeds begin to swell, plant them in a seed starting mixture making sure to cover the top of the seed with vermiculite or place them in damp paper towels to complete the germination process then move them to a small pot once you see the root start to come out of the seed.
