Maple seeds usually require stratification prior to planting and the germination basically depends on the specific variety grown. Unfortunately, seed germination is hit and miss--while some may sprout within a few months, others may remain dormant for years.
Stratification process: soak seeds in lukewarm water for 48 hours to soften seed coat. Mix seeds with damp sphagnum moss or peat and place in a plastic zip-loc bag for 4-6 weeks at room temperature. Then place in the refrigerator for 60 to 90 days to mimic a natural winter season. After the 90 days, sow in trays or pots.
