Begin starting adenium seeds by preparing a container with a well-draining growing medium, like a perlite or sand and soil mix. Place the seed in the growing medium, just covering them with the growing medium.
Water from below daily and from above once every three days until the seedlings appear. Place the growing tray or container on a heating pad and keep the temperature of the growing medium at between 80 and 85 F. (27039 C.).
Your desert rose plant seeds should germinate in one week if the seeds are fresh. If they are not fresh, it may take longer (if at all). Once the seedlings appear, water only from below. In about a month, the seedlings will be large enough to transplant to a permanent container.
