Growing Japanese Maple Tree From Seed

[Gerald W. Roe]

You need to make sure you leave the seeds on the trees until they
mature in the fall, even though they may appear in the spring.
October is about the right time here in western Oregon. Then the
seeds need to be stratified, i.e. given a few months of cold. We
just plant them in potting mix, cover them with sand, and leave
them outside until spring. Our flats are thick with maples in 
mid-spring.
