SYMPTOMS OF DAMAGE DUE TO ADVERSE WEATHER CONDITIONS

Extremes of weather can also lead to plant injury. Common weather-related injuries include COLD INJURY shown in this photo on spruce. As the new branch tips (candles) began to expand, the tree experienced a period of cold that was severe enough to kill the growing tips. To correctly diagnose this kind of injury, you must remember to ask a grower when during the season symptoms first appeared and whether any unusual weather occurred just before the onset of symptoms.
