How do I propagate maple trees?
Plant SeedsPropagate maple trees from seed by planting them in moist, well-drained soils and storing them in an area with temperatures slightly above freezing. Plant the seeds 1/4 inch deep in the winter season, when outdoor conditions are cold enough to promote germination. Over the next 35 to 90 days the seed will start to germinate and produce a maple tree seedling. The University of Wisconsin estimates maple seeds have a 95 percent germination rate.Grow SeedlingsStore seedlings in an area where they receive 65 percent shade, as too much light can stunt the growth of the seedling. Planted outdoors, 50 percent of the seedlings will still be living after the first year, according to the University of Wisconsin.
