Germinating Paperbark Maple Seeds (Acer griseum)

I have seeds from a Paperbark Maple (Acer griseum) and want to know the best way to germinate them. Should I refrigerate them? Plant them on the soil surface?

Stratification and Sowing

If you're in a region with cold winters, sow the seeds outdoors now. Plant them at a depth equal to their length in good potting soil, keep the container watered (don't let it dry out completely), and leave it outside for the winter. Natural cold stratification should break dormancy, with germination occurring in spring. If that fails, or if you're in a mild climate, place the pot in the refrigerator for 60-90 days (moist, sealed in a plastic bag), then move to 70°F. This mimics winter-to-spring transition. Paperbark maple seeds have double dormancy and can be slow—patience is key.
