growing Japanese (and other) Maples from seed
I just ordered some seeds from Sheffield's Seeds for:
The three "Japanese" types are "fresh" seed, from fall, 2013, as opposed to dry older seed, per Sheffield's, and per the website only need 12 hours soaking then 120 days stratification.
The Acer nigrums are from 2012, & I worry about their viability, but Sheffield's says germination should be over 90%. For these they recommend a 24 hour soak, then 90 days stratification...
Can anyone comment on this? For the first three, is 120 days right? That's four months stratification - seems long.
For the A. nigrum - am I likely to get decent germination rates from these 1 year old seeds?
