Abiotic Problems - Weather and Exposure Stresses

Weather extremes and exposure to these extremes cause a lot of stress and damage to evergreens in the upper Midwest. In particular, winter drying of foliage, freeze drying of foliage in later winter/early spring/early autumn, winter cold temperature damage to foliage and stem tissues, and snow/ice breaking damage are common abiotic agents of damage.
