Spruce cones should be harvested as soon as they fall, or the seeds will drop out and may be lost. After collecting the cones, allow them to air dry fro a few weeks. Seeds do not need a pre-germination chill, but it might speed the germination process to mix them with moistened growing medium, sealing in a plastic bag, and refrigerating for about a week. After pre-chill, sow seeds on the surface of moistened seed starting mix and keep trays or pots at room temperture. Seedlings should appear in 30-90 days. If you start seeds now, you can transplant out into the garden when the weather warms in the spring. Or, you can start the seeds outdoors in pots, planting now and allowing the cooler winter weather to chill the seeds prior to sprouting in ghe spring.
