Giant sequoia seeds and cones - any advice on gemination?

[fcharlton]

So I picked these cones up from a branch that had fallen from a mature giant redwood. Anyone had any luck getting seeds to germinate? One or two seeds seem to have come out already as the cone opens up indoors. Should I pop them in the freezer first? Or is it a lost cause trying to breed from UK specimens in the first place?

I know one of the lads tried this years ago from a redwood we pruned, horrible bleedin job btw. Didn't work for him. He did also try putting them in the fridge or freezer I can't remember which.

Just let the cones dry naturally, and as they open you will get hundreds of seeds from each.
My neighbour has a young tree in her garden, grown from seed but not sure what the germination process was.
I’d guess like ash, fresh seeds will be easier to get to sprout. Dried/older seeds will take much longer.
Almost certain they will require several weeks of cold stratification, and then some very tender nurturing if you do get any to sprout!

It's a along time ago, but baked some of these to speed up seed collection as serotinous

put them in a paper bag in warm dark area the seeds will drop out in a few weeks time there is a lot about it if you google it
