Being completely covered in snow protects your trees from all the weather related issues- severe cold and drying winds- but potentially can damage branches from the snow load. If I lived in the MI snow belt on the west side, and I had a well developed A. palmatum, it would be under cover somewhere. The cold won't damage an A. palmatum if it's in a protected spot with the roots properly mulched.What is preferable, completely covered in snow (have about 30" in my yard right now) or in a garage that I guess will get to about 20°F.
Outside temps will be 3-10°F for about 5 days straight. Have several JMs that I'm mostly concerned with, others are all natives to my area and cold hardy to zone 3 or so, so not really concerned about them staying outside.
