To germinate store seed at 40F for 2 months THEN>>>
Lightly cover soil temp 65-70F & takes 14-60 days to germinate

The trees self sow for me by just allowing the seeds to lay outside in the soil over the winter. Next spring, zillions of seedlings all over the place. Let me know if you would like seedlings next spring and I can send you as many as you want. I have already gone through since early spring and pulled this year's seedlings up although there are probably a few still lurking somewhere.

This is the only discussion on zelkova.

I have to know how do you germinate these I am finding it very hard.

I put them in refrigerator and after that froze them for 3 days.

Then tried putting them in sunlight or in warm room, still nothing. They look healthy but not sprouting.
