SYMPTOMS OF DAMAGE DUE TO ADVERSE WEATHER CONDITIONS

Often lack of water is a common cause of injury to plants. In this photo, the yew is suffering from a disorder caused WINTER INJURY. Damage of this sort typically occurs in the early spring when air temperatures rise, but soil temperatures remain cold, often due to a layer of snow. As the air temperature rises, the foliage of the shrub becomes active and begins to use water. Unfortunately, the root system of the shrub, which is experiencing colder temperatures, does not become active. Thus there is no way to replace the water that is being used by the foliage, which becomes desiccated and dies.
