Please help my thuja green giants

[one.two.tree]

My poor thuja green giants managed to do fairly well since I received them last spring. Unfortunately the winter was harsh on them and I’m not sure if that was due to lack of water, Colorados constant temp swings, and/or my overall lack of knowledge. Are these things completely dead and beyond the point of no return? If you think they may have a chance, what would you recommend I do to nurse them back to health? I was hoping to get them in the ground by next fall or Spring 2022. Thank you in advance!

Plants in pots are vulnerable to winter weather as the frost easily penetrates right through the rootball.

If you try the same again sink the pots into the ground for the winter.

Seeing the words Colorado and fall suggests the writer is in the USA, the plants have most likely not made it over winter due to the pots freezing and the top then desiccating due to lack of water. These plants are in an advanced state of terminal necrosis, I would suggest you try again but don’t let them freeze maybe also some wind protection.
