In the deep midwinter, evergreens offer a vibrant flash of color in the otherwise bare and leafless yard. But in spite of their renowned hardiness, they too can suffer from the consequences of plunging temperatures.
Winter burn can leave the green foliage looking scorched and brown. And though burn implies heat, it is caused by the opposite – extreme cold – which means the trees, plants and bushes can’t draw up moisture from frozen soil. Winter snow can hide the worst of it under a picturesque white blanket. But as the thaw sets in, half of the evergreen can appear dead or dying.
