Evergreen foliage is killed during late winter. The sun
thaws the foliage, which then refreezes rapidly when the
sun is blocked or at sunset and the foliage temperature
rapidly drops. Thawed foliage may lose water that can't
be replaced by roots in frozen soil, so the plant dries
out. The symptoms are browned foliage in the spring,
especially on the south or southwest side of a planting or
plant.
Prevent the problem by shading susceptible plants. Use
burlap screens, discarded Christmas trees or any other
simple shade source. Because injury usually occurs in
late winter, you need not apply the protection until after
Christmas.
