Seeds 2022

You are doing the best thing by planting them. You could even bag up a small plant pot with some of the seeds and soil and put back in fridge if you want to stratify for longer.

Your paper towels could have been too wet if rotting occurs. They need oxygen as well as moisture. I use damp (not soaking) peat or seedling potting mix for strat.

 

How can i prevent dampening off or stop it?

 

A well drained airy soil mix works for me

 

And copper, copper, copper. Sorry to hear about the mold. I agree the PT would have been too wet.

I do the same as Maf.

Re: A. obtusifolium, mine has never made seed, or even flowered. But I do have a seedling from @alex66 s garden, (germinated by Phil) which I think is maybe a hybrid, but I'm not sure. It has really big, and somewhat more pointed leaves. It's a really nice looking seedling, still in a pot. But both the seedling and the large established maple in the ground are deciduous here, though I'm sure it would be evergreen in your climate.

 

How do i apply copper? Like in what form?

 

Pulverized, as a mist. I use a squeeze bottle for small applications, or a big sprayer with a lance for larger trees.

What you want to spray is "Bordeaux Mix", which you can google, or some form of soluble copper sulfate. I believe many Americans swear by a product called Phyton27, although I understand it's expensive.

 

i removed the rest of the seeds from the paper towel and replaced the medium with potting soil. nothing to remove mold, but im guessing soil or sand is much better than paper towel. they will be stratified in potting soil from the garden now, is that a better choice?

 

Seeds new location

 

Some more pics of the sugar maple seeds (they are the brown seeds you see in the photo . Cant wait for them to sprout, hoping i didnt put too much soil that will rot these seeds, especially that they are removed from the pericarp.

 

The medium looks good so they should be fine.

I hope the sugar maple seeds will sprout

 

A. pensylvanicum seeds from the MS seed exchange are sprouting. Fridge stratification started 1/13.

 

thats unusual. dont they take more than 3 months? what method di you use?

 

Hey D, did they give the source of the seed? Usually it gets included.

I guess I'll be checking seeds in the fridge today! One advantage of not using peat/sand, I guess it makes it really easy do spot the radicel.

 

Hey E, Netherton Arboretum, England. I hope you find a pleasant surprise once you check.

From my experience nothing is set in stone when it comes to seed germination. Most give the most common estimated time.

 

So any seeds germinated?

 

Nope, not a thing! Just as well, it's really too early here.

D, it will be interesting to see how those come out. A. pensylvanicum loves to hybridize. I have friends who sent me some collected in central Maine, but I don/t think the seed was ripe; we'll try again at some point.

 

I get excited when the word 'hybridize' get thrown in the mix.

 

LOL Maple geeks, for sure!

 

Bigleaf maple seeds that were sown a week ago are now germinating. Pretty cool. A bird tore up one of the seeds though :(

 

Some more photos of the bigleaf maple seeds

 

I got a few packets of seeds from French members. I planted them all outside (the seeds!). The first one to germinate is from a dozen seeds labelled 'Okushimo' :

 

I think 'Shishigashira' may have the smallest seeds.

 

Noice. Did you participate in the main MS seed distribution as usual Alain?

 

I didn't. I was not sure it was even possible considering the new customs rules. Anyway, I thought I had enough trees that I can't place where they would naturally grow. I sent, and got seeds from French members, but they were mainly "palm/oenum".
