Move it away from roof snow fall? I have, or more properly had a row of blueberries under a 2nd story deck. My wife shoveled the snow off the deck and it all fell on the blueberries. They got shattered and died.

The moral: don't place valued plants where heavy snow will fall on them.

I plantd 5 holly plants under some spruce that the bottom branches are thining,they are totaly exposed to the wind
and get quite dry in summer.How much are yours growing per year.
