Acer Palmatum from seed?

[atlarsenal]

What are my best chances for success on these Japanese Maple seed? My guess is they are probably not mature enough but they were there and I was there and I wasn’t going to be back so I plucked them. I have grown red maples from seed off of the ground, pop them in dirt and they come up, easy peezie.

Looking for advice on how to treat these for success. Thanks Guys.

I'd say chances are essentially nil.
Out of curiosity, have you cut a seed in half (hold the samara and cut thru the thick part)? Since maples make samaras even absent pollination, the seed may be hallow/empty and, hence, not viable even if it were ripe.
