I would wait until late winter myself.

FWIW, I tried a lot of ebay seeds with very limited luck a few years back. Then this last year my Ogon had some cones. No seeds germinated for me.

I did have good luck with so e seeds from FW Schumacher. They listed germination rates and were close to right even with my limited skills. I am not sure if they are in business still or if they ship to Europe.

its a neat project. Good luck.

I had very good germination rates with the metasequoia seeds from treeseeds.com. They always give you a lot more seeds than you order as well. When I ordered 100 norway spruce seeds I received over 200!

I'm in Z8 Texas and planted Bald Cypress seed in late September and they did not survive the winter. As these trees are similar I would also predict failure of your seedlings to harden off sufficiently to survive winter. Best to wait.

So the redwood seedling can survive winter only if their stem is wooden or can they survive even smaller? Because my giant sequoia seedling are no more taller than 4inch and their stem is ~ 0.07inch wide.

And i will order a pack of dawn redwood seeds later this year and cold stratify them until february.
I may sound as a beginner "because I'm one :)" but I'm interested in this kind of hobby and getting info from you guys, it helps a lot.

I would think for the easiest time you should keep them on a normal cycle. I'm sure you could do something like start them now and bring them inside the garage every night until they go dormant in December then let them out of dormancy a few weeks late if you can.

Just seems like trouble though and like you'll have a lower success rate.

Here is what I mean by just getting a woody stem...this is one of mine yesterday. Not all the way woody, but starting.

Here is my biggest giant sequoia seedling. It's my first attempt thou and I may not give it the best environment to grow and that's why it's so small. It sprouted in early/middle may and it looks healthy so far. I guess this seedling doesn't have any chance to survive the winter? I will for sure try again next year.

I wouldn't throw them out by any means. Just pay attention to the frosts if things look tender. May isn't August so its not real far off schedule.

So after 2 months all 8 giant sequoia seedlings survived and they started to harden "getting woody". The picture attached here is the same seedling as my last post I made here 2 months ago.

I'm glad I didn't threw them away :)

Can anyone tell me if these seedlings are Dawn Redwood? I found them growing under my 60 ft Dawn Redwood.

I dono ,,,but Nancy , why don't you start a new post ?
