Dear Kris,

in our continental climate, we usually take advantage of winter chill to
stimulate germination of seeds of  Ginko biloba (and many other hardy
plants). The task is usually undertaken  in late December or Jannuary.
Would them germinate right now? I couldn't say. I'm not a specialist but
imho you should perhaps consider the possibility of somehow artificially
chill the seeds into a refrigerator or something like that before
proceeding. Or even better, if you're not in a hurry and you live in a
country where it freeze in winter, postpone the task to next winter. We had
a thread recently in another list where people had similar problems with
germinating of stone peaches in country with low "chill winter units" (not
sure about the term but I hope you've got the idea) so I could foward to you
the main facts if you wish.
Anyway we use to stick seeds into 8cm square pots, the seeds must be sown
really superfically, as I've told you, seeds need to feel the frost to
germinate successfully. As the plant is an "easy germinator" a mix let's say
of one part sand and one part of loose soil or compost or anything like that
wiil be ok. The only cause of  failure (as far as it concern Italian
nurseries) is that we sometimes forget that mice are very fond of tender
sprouts from Ginko seeds, so be carefull if rodents are a problem in your
area.

Hope this help
