What to do with juniper cuttings in fall/winter?

Hello,

I started gardening this year (thanks to covid) so please bear with me if I struggle with some simpler concepts. I am in Toronto, which is zone 5 I believe.

I took some juniper (chinensis) cuttings around June this year and I put them in some soil and covered it tightly with transparent plastic to create a greenhouse effect. I have never watered them so far, but the inside of the plastic shows condensation to this day and also moss growth. Also I leave them out in the open when it rains so it probably absorbs some through the drainage holes. So I'm inclined to think that maybe it's alright to not add extra water.

They have finally started showing some new growth in the leaves after a few months. I took one of them out of the plastic greenhouse and saw it has 2 nice long white roots and potted it with some bonsai soil (bought, I have no idea of the mixture). I tried to take another one out which also showed new leaf growth, but noticed it hadn't rooted at all, so I put it back inside the greenhouse for now. And there are a few others which are also showing leaf growth, but I haven't checked if they have rooted.

What should I do with these during winter? The ones that have rooted and the ones that haven't (but are still showing new leaf growth). Should I leave them inside the plastic greenhouse until spring? Should I pot them and let them get fresh air instead? Do they still need sunlight/watering during the dormant winter period or can I put them indoors (from when to when?).

I found a lot of examples on google, but none that seemed to fit my timeline. Most people seem to plant their cuttings in fall and then have them ready by next spring for new growth. Now that (some of) mine have rooted already in fall, I'm not sure if I should keep them in the greenhouse setup until spring or pot them now just before winter.

Please let me know if I can provide more details. Any advice would be greatly appreciated :)

When I was propagating shrubs at work (including junipers) we left them in the propagators (covered in polythene as your are) until the roots showed underneath the seed trays/plug trays. When they seemed to have sufficient roots showing they were put out into the tunnels (unheated) and left to harden off, watering as and when needed, which was not too often. Well done for getting them to strike, and welcome to the forum as well (y)

Thank you, that's very helpful. When you put them in the tunnels, did they receive any direct sun?

In the tunnels all the plants got whatever weather was thrown at them. We only grew shrubs, climbers and conifers - and a few trees. Remembering of course that tunnel polythene is made for the job (please don`t ask me the technical details)
I wish you continuing success with your plants - and don`t stop gardening when this covid stuff is out of the way ok :D
