Answer: Geranium seeds benefit from a pre-chill prior to germinatoin. If you sow seeds in flats in the autumn, you can sink the flats into the ground next to a north-facing wall, cover with plexiglass, and leave them there all winter. Then in the spring take the flats indoors and keep them at 70F - 75F until the seeds sprout. If you start seeds indoors in the spring, give them a pre-chill treatment in the refrigerator. Just sow in trays on the surface of moistened seed starting mix and barely cover with additional mix. Seal each tray in a plastic bag, and place in the refrigerator for 2-3 weeks. Then remove the plastic and sink the trays into the ground in a shady location outdoors. Keep the soil moist. Germination will take from 3-90 days so don't give up on your seedlings!
