Quote from: CG100 on December 29, 2023, 04:40:07 AMIt (the fridge, or freezer) doesn't really replicate any natural process and given that we don't really understand how germination is delayed in any detail, I would agree.
I think I'm going to place them outside for the next couple of months as opposed to putting them in the fridge. I remember reading an article about germinating Pediocactus seeds and the author was emphatic that it was necessary to have them outside exposed to the elements during winter with daily freezing and thawing and light to get them to germinate. I suspect the same is true for Carline thistle. I'll probably place them in the garage only if the temps are going way down below freezing, just because it seems reasonable to do so.
It's an adventure. If I can get them to germinate then I'll see if I can get them to grow here. That will be another adventure!
