First, prepare a pot of sterile organic potting soil. Dampen it to a depth of several inches, but do not make it soggy. Place an oleander seed on top of the moist soil and sprinkle a thin layer of soil over the top. Then sprinkle a thin layer of sphagnum moss. Cover the pot with a sheet of plastic film to maintain humidity. Place the pot in the light during the day and maintain its temperature at between 21 and 25 degrees C. Maintain the dampness of the potting soil, but do not overwater.
They typically takes at least 30 days for germination and may take as long as 90 days. Once the seed begins to germinate, make sure it gets bright light throughout the day.
