dead trees
Winter desiccation occurs when the needles of evergreens are exposed to high winds and low temperatures. They dry out quickly because the ground is frozen and the tree is unable to replace the water lost from the foliage through evaporation. We see more damage related to this issue in some years than we do others. It is a common issue in Alberta, especially in trees with shallow roots like Spruce.
