I moved from California to Virginia just a few years ago and am still learning what each tree can tolerate. Winter before last I buried it in mulch as well as all my other trees and didn't lose a single tree.
Then I had kind of a moment like "Why do we need a cat when there's no mice?"
So last winter I just put all the trees out of the wind on the ground. And I lost a ton of them.
Lesson learned!
