Japanese Maples from seed

Co. Limerick, Ireland

Hi, has anyone any advice about how to germinate these? I have tried a few times but none have ever grown. I have tried them in the fridge several times and I currently have some Tromenburg seeds in the cold frame for the winter. I am getting the seeds from reputable online suppliers as I don't know anyone who can give me fresh seeds. Has anyone had any success from bought seed? Any advice will be gratefully received...

I've not purchased any seeds, but they germinate under the tree, just laying on the ground, so they can't be that difficult.

Maybe you could moisten a paper towel, put it around the inside of a glass, with the seeds in BETWEEN the glass and the moist paper towel, and cover with saran wrap - you can watch them and see if the germinate. When they do germinate, take them out and pot them up.

I came across this link.

Are you putting them in the refrigerator in something damp for long enough.

I can't confirm it, but I suspect that the seeds remain viable for very long.

Thank you for your help, I have heard that they germinate much easier from fresh seed. We have Sycamore trees in the garden and I find seedlings coming up everywhere each year but I just had no luck with the Japanese Acers. I think maybe I haven't left them in the cold for long enough, I was only giving them 6 weeks as advised on the packet instructions, I will leave these for longer and see if it works. Thanks Doug9345!
KayJones, I like your idea with the paper towel and glass, that will work very well for a few of the seeds I have, very helpful!

I've also read that JM seeds need double stratification (to simulate 2 winters not just one) for best results. So at a minimum you ought to leave them in the fridge longer than you would for your typical seeds.

...I have one!! I left the seeds out over the winter and when I checked the tray today I had a seedling! I think I just hadn't left them in the cold for long enough before! Delighted!
