    I have 30+ bags of seeds that I stratified, first at about 20° for about 40 days for the japonicum, shirasawanum, etc, and in the fridge from Jan. 6th for the others.

    4 days ago, I checked the bags and saw nothing sprouting. I decided to put them all outside, where temperatures went down to -3.7° C and up to 14° C in the afternoon, thinking low temeratures at night (they should be slightly above 0° C in the coming 2 weeks) and warmer temps in the afternoon would reproduce the natural process of seeds going out of dormancy.

    I just went out to check the bags and found these two are waking up:

    Pretty good germination already here, one was so early (A. monspessulanum) that I got to the bag late, and the poor things have damped off. Waiting for some secondaries from that batch, hope to get a few. Do have granatense, pauciflorum, pentaphyllum, sinense all up otherwise. Some Dasyanthus too. Got a cold frame this year, hope it will help with these earlies!

    All these, except the one in the top-left corner which is 2 or 3 years-old, are from a 'Palmatum dissectum atropurpureum' :

    Wow, those are nice! Now you just have to not kill them. I am very talented at killing dissectum seedlings.

    Here are some of my 2021 seedlings, taken mid Sept. The individual pics are Acers: metcalfii, pictum var ambiguum, pauciflorum, granatense, micranthum, sinense, diabolicum, and pentaphyllum.

    I don't want to put you down, but I have nothing to learn from you on that matter, Sir.

    <LOL>

    Actually, I even "tempted the devil" as we say in French, "j'ai tenté le diable" : I repotted them about 3 weeks ago. I added some fertilizer with a high proportion of K, which I think is good for the roots.

    Je croise les doigts (fingers crossed) : apparently they didn't suffer from this untimely repot. No leaf has fallen. Some of them were already burned on the sides, but they look just like they were before, even the very tiny one with green leaves with a red margin (3rd from the left in the top row).

    I have just collected a couple of seeds from 'Hana matoi' : I promissed I will send some to a friend, but I'm impatient to see how the ones I'll sow look - if they germinate.

    LOL.

    I don't have any issues with repotting now, though I do find fertilizing a good way to kill _even more_ dissectum babies. Wait, this is getting too macabre. (staggers off, muttering).

    Well, so far, so good. and mind you, I didn't add so much fertilizer, just the right pinch of it.

    Anyway, as you mentioned before, it's hard to keep dissectum from seed over the second year, so what do I have to lose ? Perhaps the "unusual way" is the best ? I'll keep you updated ;°)

    But I bet you at least 8 out of 12 will survive !

    On verra bien, mais j'ai confiance. ;-)

    Last pic from this year's seedlings. Getting ready for dormancy, some of the A. pictum v. ambiguum are showing pretty color. A little yellow red on the metcalfii (left) and yellow as expected on the granatense (right).

    I went to collect seeds at the local japanese garden in the weekend.

    50% of them I put into bags in the fridge at about 0-2 °C. I'll probably sow them somewhere around Feb.
    50% others I sowed in the greenhouse.

    Any tips are welcome.

    One of our successful members wrote up an article for the MS FAQ. Although the faq is sadly incomplete, the article is very helpful.
