Winter Protection-Is this okay?

[Kahless]

I live in Minnesota and the temperatures get down to -30 F. I have only cold hardy deciduous and a few junipers (bush honeysuckle, acer rubrum, potentilla, hornbeam, and a trident maple) in this cold frame.
I live in a condo and only have access to a south side. I have them surrounded by chicken wire covered in tarp on all sides to block wind. The trees are surrounded by mulch and covered in a lot of snow since it has been snowing a lot. Hopefully this is okay.
I recently put a tarp over the top also, since the sides did not come up high enough to block all sun and wind. It is vented. Hopefully it is okay to have this on top.
Is this set up okay? Will this be adequate protection from deep freezes and drying out? Is it okay that some of them are almost completely covered by snow? Thanks

I think it would be easier to take them inside ,wouldn't it ?

That's a very bad idea for cold hardy species

That's probably the best you can do for species native to your area. The snow covering is extremely helpful for less hardy species like the trident- without it, I don't think it would survive your winter in that spot.

Are there grommets in the corners of the tarps and tethered or synched, to bolster against winds?

I have it tied and clamped in a few places
