fishbone

I will think about how I'm going to keep it outdoors and still be able to enjoy it regularly. Maybe put it up on a window sill or something like that.
Now, I'd really like to get this thing to overwintering. I've read around about junipers and I think I know what I need to do, please correct me where I am wrong:
-I need to give it about 8 weeks of dormancy; should I just leave it for the entire winter?
-I need to insulate the pot in a styrofoam container with mulch; this thing is small, 6in long, 4.5in wide, 2in deep. Can you recommend, based on this, how much mulch?
-need to give it indirect sunlight and protect it from harsh winds

Would keeping it on a window sill/edge work, as long as it's not in the path of strong winds? It'd get a lot of direct sunlight that way though, mainly after 1PM until sunset.
Location, please tell me what is best. Unheated garage by a window or outdoors, maybe under my deck, where it would get snow on it etc but not any wind? I checked and my garage is abour 2-3 degrees above outdoors temp. Basically right now it's 34 outside and 36 in my garage.

Is there going to be any issues with just taking the juniper outside just like that, from 70-degree weather to sub-40?

Any other particular photo I should take to get a good ID? Or do all Juniper variations pretty much require almost identical conditions? If needed, I can also provide a picture of the place in the garage I had in mind and the one under the deck.

I've read that Junipers can stay green for weeks or months after they have essentially died. This worries me because to me this is like a plant that doesn't "talk back". How would I be able to identify signs that the plant isn't liking one particular thing or another?
