Answer: Two key ingredients for pansies are cool soil and darkness, says Kurt Schekel, ornamental plant specialist at Washington State University in Pullman. Pansies germinate best at 60_F soil temperature, covered with a thin layer of soil to keep the lightout, he says. Start them in a cool indoor location in a sterile potting mix and they should germinate within 20 days. Prechilling the seeds in a moistened soilless medium in the refrigerator for two days also helps germination.
