[NAFEX] Are Grow Tubes okay to use where it gets cold?

I can't refer to tubes and grapes, but I did have a lot of grape vine loss 
from voles this last winter....
I did do an experiment with a type of grow tube on 2' to 4' high grafted 
apples and pears in the nursery bed this last winter.
I did not have time to get all screen wrapped ( mouse protection) so used a  
tube around a couple dozen and filled them quickly with soil , all this was 
done just before freezeup. (after dormancy) I had one rot inside the tube, 
so perhaps it died for unknown reasons, or the bark could not stand soil 
contact.  I was a bit late geting the soil off of some. The reason for the 
soil was to avoid the temperature extremes both of our winters - and of any 
tube exposed to sun in late witer. And to protect from any mice that get in 
if the snow gets up to grow tube height ( it did).
My conclusion is to continue the experiment on a limited basis next year, 
and perhaps try peat moss instead.
Del, where the Trailman crab (earliest apple) is showing pink tip on 
blossoms and other apple's buds are still just swelling.....
